Ashraf Ssebaggala: I have a 2004 Nissan Altima and of late the temperature was going up and
when I checked the radiator, the water level was down. I added water as I
tried to observe for a few days if it was leaking. I found no water on the
parking sport whatsoever. I have topped up the radiator level like 3 times
now but last Friday when I took it for a regular oil change, the guy at the
shop opened to put the oil and he said there was water mixing with the oil
(there is a scene of like melting ice cream even on the engine cap, and I
can also see it with the oil deep). He said this is a head gasket that had
blown. I wanna use the K& W seal as you have suggested but what do I do to
the water and oil in the engine? It is too expensive on my side to open the
engine up for a new gasket.
In fact, when I press the accelerator pedal in the morning as I am starting
the car, I can see some water coming out of the exhaust pipe. Please help.
Thank you so much!!!!A
Adolph Oliver Bush: Good video. Looking at fixing a small head gasket leak on my 95 miata,
which from the factory has a bad route for coolant, leading to head
warpage. it has 182k on it, runs great, but clearly losing radiator fluid
slowly. If I don't install the coolant reroute kit on this engine, am I
wasting my time doing the Engine Block Sealer?
john murphy: I got a gm 4.3l had a bad lower intake manifold which let all the coolant
leak out . And overheat . I fixed The intake .. now I got a bad head gasket
. Which I tested and it def. Is bad . Should i just take the time and buy
the gasket kit and do it that way . Or does this stuff really work and I
can save my self the headache . ??
Thien Phan: I currently have a 2000 Honda Prelude (4cyl) . It is currently diagnosed
with a "very small head gasket leak" according to the mechanic. Symptoms -
cold start up, it has a rough idle. Spark plugs had water in it. And
Compression test was off on cyl #3 & 4. The car is currently not
overheating at all. There is a new radiator, upper hose, and water pump,
and the electric fans are working. Should I still use this product because
I'm afraid it might gunk up the new parts I recently installed, causing an
overheat problem. Also how many ounces would be needed for a 4 cyl
Marcus Lobo: Hey, I found this video late and ended up using block sealer without
draining the coolant. Will that cause the block sealer to not work?
crackermoves: Hello how are you? I have a little coolant mixing with oil (not a lot)..
The green coolant dribbles out with oil change and separates from the oil
running into the drain pan and runs off separately as water, Not much thank
goodness & Not frothy chocolate goo like in extreme cases, the engine runs
perfect but will steel seal help??. I don't think I have a blown head
gasket, it never over heats, all cylinders are compression tested 142-150
and spark plugs are dry.. Could it be the upper Intake gaskets instead??
Chevy Astro Vortec 4.3 v-6 Thanks much buddy ..
Wm Wallace: I've used it and it worked great. I had to use 2 applications . . but the
2nd treatment did permantly seal my head gasket. I drove the truck from IL
to CA and all over CA . . two years later it was still fine :)
dshmechanic: Maybe I'm wrong, but I was always under the impression that Magna-Fluxing
will only detect cracks/faults on iron (magnetic) cylinder heads and
blocks, not those made from aluminum. Was I told wrong, or is what I was
told true? Also, in my opinion, the easiest, most accurate, and
inexpensive test for head gasket/cracked block issues has got to be the
combustion leak detector method. The test kit can be bought at Autozone,
and it is a professional grade re-useable tool that a mechanic or
DIY'er can use a lifetime. It comes in a red blow molded carrying case, and
if you do buy it at Autozone, it is labeled "Block Tester". Just bought
mine last week at my local franchise and it was $25. The 8 oz. bottle of
blue dye was $8.99. It's super easy to use, and best part is it is
foolproof...if you're not colorblind, lol.
curtis glass: You do have to drive it 500 miles before L in the engine coolant settle
Stephen Ness: I have a 2005 Chevy Tahoe with the 4.8L V-8. I have recently noticed that
my coolant reservoir level drops slowly over time. It does not over heat,
but the level does go down and there is no visible leakage. The level in
the reservoir has dropped about an inch in the last week or so. Also, there
is no engine misfire, the check engine light is not on, and there is no
white smoke from the engine or from the exhaust. I have, however noticed a
very small hiss coming from the back passenger side of the engine after I
turn it off and it slowly reduces until it stops about 45 seconds later. I
think I have a small head gasket leak, but I am not really sure and I dont
want to spend a ridiculous amount of money to find out. I have toyed with
the idea of getting an engine block sealant but I dont want to take an
entire weekend to use it just to find out that it won't help. Any ideas as
to what might be causing the coolant leak and hiss from the engine?
Mangler Malachi: There is something I don't understand. If it is copper metal flakes that
melts and clogs the hole in the gasket or engine block, what keeps the
copper metal flakes from "re-melting" (if that is a word) whenever the
engine temperature goes back to its normal operating range and
redistributing elsewhere, like in the radiator passages and/or thermostat?
Neil Militante: After I changed a new radiator, should I changed my oil too ..Before the
chandler: I have a blown head gasket in my 2002 Chevy Malibu. I tried this and so far
so good. Will update you how it came out about six months down the road.
Thank You. RC
anthony james: Not overly technical, yet sufficiently explained! He covered everything
pertinent to what I've experienced. Seems like a really nice guy, too!
Javier Najarro: Hi! Austing. Iyhe only question I have is: during those 500 miles., do you
drive with the heater and defrost on?defrost on?. Thanks, Tony
timothy green: I have a small coolant leak behind the water pump.I think there may be a
small crack in the block. The motor is a 4.0 straight 6. It is not
overheating but i keep coolant topped off. I picked up a green bottle of
k&w pour and go. Do you think this will work for my application?
Drew Thomas: Have a 1990 Nissan Stanza. Had a radiator leak and was going to replace it,
but didn't have time before my kid had to go back home. I plastic welded
the leak to get the car going back to it's home over 300 miles. The car
made it fine, but a few days later it overheated badly and could not keep
coolant in it for more than 10-15 minutes. Took it to mechanic and they
confirmed blown head gasket. My question is with a substantial leak like
this will this sealer work on a large leak of this size?
Stevez Rock \m/: THANKS FOR THE HEIP BRO SAVED ME SOME CASH TRYING IT THIS WEEEKEND! WISH ME

John Steimle: Good video. I have a 1992 Honda Accord Coupe LX with 305k miles on it. A
couple months ago, I noticed I had to constantly top off the coolant. My
mechanic did a pressure check and found the water pump was leaking and he
replaced it and pressure checked it again with no problems. Then recently,
a coolant return hose ruptured, resulting in engine overheating. My
mechanic found fuel and oil in the coolant (gunk on the radiator cap) and
coolant coming out the exhaust. He said I had a blown head gasket. $1300
to fix. I didn't want to put that much into such an old car, so I had him
just fix the hose. He said it still had coolant coming out the exhaust and
that the coolant/water would quickly boil when I drive the car from
cylinder heat escaping from the blown head gasket and directly heating the
water, which is does. You can see fluid in the reservoir boiling. Do you
think K & W Engine Block Seal would help this situation.
Neil Militante: Hi I have 86 corolla my radiator water was brown and my water level was
low....so I pressure check it...I found out my cap was bad. My planned was
to flush it and put new antifreeze ...so I installed new thermostat it was
sluggish...new cap and flush the radiator ..when I add a new antifreeze
while running my car started to smoke white and my engine started boggin
and check engine came on then I stopped the engine...then I saw a leak from
my cat watery oil then I pulled my dipstick man milky oil..
Tyson Kinsley: I have taken my Subaru Outback 2001 (2.5L engine, auto tranny) to the
dealer and they confirmed the infamous head gasket leak. (I also had valve
cover leaks but DIY'ed that myself) my question is this...what's the
difference between an Internal amd external leak? I can visibly see places
where oil is coming from on the engine block and they have antifreeze
mixed, but I have never had temperature issues before and I dont seem to be
using any large amounts of antifreeze. Will this sealing trick help any of
my leaks or is my problem something completely different?
mikeyd19841: I have a 99 vw jettea 2.8 vr6 i just bought and i got shafted and it has a
bad head gasket! I noticed that the temp gauge does not move so tmrrw i am
going to remove the thermostat to see if it is bad! Is the k&w better than
the blue devil and will the k&w gum up my system? You said it uses copper
compound to seal the crack!
Mike Case: Hi all, my wifes 2001 mazda mpv's return hose to the water pump housing
broke clean off on her while driving. Luckily she shut the vehicle off
when she noticed the temp gauge was high. That being said I found a new
water pump assembly and replaced it refilled the reservoir and told her she
should be good to go. upon checking the coolant level I found it was low
and had to refill probably about a gallon every 4 days, so I said shoot
sounds like the head gasket is leaking...
And then I found this video on youtube and after checking out the reviews I
ordered up some of the sealant on amazon. When the product arrived I
followed the instructions from this video and put about 500 miles on the
vehicle in the course of three weeks. The level did change after initial
start-up and subsequent first drive. I refilled the resevoir and three
weeks later the level was now holding full.
Finally i flushed the radiator and refilled with regular antifreeze/coolant
and after two weeks of checking this product and repair procedure seems to
have done the trick...saved me thousands of dollars and/or getting another
car all together. For around 25 bucks and less than two actual hours of
repair time I'm happy as a clam! Thank you so much for this youtube
trustmymechanic, You guys Rock!!!
Gun Rule: WHAT COLOR IS THE CAN OF K&W BLOCK SEALANT... I FOUND AN ORANGE METAL
CAN... BUT I ALSO SEEN A REB / BLK METAL CAN OF K&W BLOCK SEALER
Denharrio Wilson: I have a 2001 Bonneville 3800 enigne.And maybe 10-15 miles in my route my
car start to overheat and white smoke from under the hood, sometimes I
smell a bypass of oil from the vent. help me.
Ernest M: After seeing this video we bought the block seal and we applied it to a vw
passat 2005 with 127k miles that was loosing coolant through the combustion
chamber, it sealed immediately but we waited about 500 miles, after few
days the system became over pressurized and the coolant flange piece in the
engine rear ruptured,well we replaced the piece, we then flushed the system
and we replaced the coolant and it kept doing that same thing, should we
try the block seal again? I appreciate any help.
ozan edmonton: hard to hear you
could u speak up next time ?
VItimmyy: I have an 05 durango 4.7l it's been having a bit of overheating issues. The
water pump blew I fixed it didn't heat up for a couple weeks then started
over heating again. Changed rad cap and thermostat was good for another
couple weeks. Now I've noticed I am getting low on coolant every couple
weeks but there's no external leak I can see. Everyone I talk to says head
gasket but I don't have any symptoms. No loss of power no steam or white
smoke nothing. There was one time where some white smoke came out but that
was a couple months ago hasn't happened since I was in a parking lot
idling. I've came across this video witch seems good but you said make sure
you have at least 2 symptoms I have none should I still try this stuff and
maybe I have a very small head gasket leak? I'm tired of paying shops to
say they can't find anything wrong. And I don't wanna do a head gasket
myself if it's not the actual issue
Adam Rodriguez: How much for sealer??
Junk Filter: I have an oil leak I think is coming from the timing cover. Do you
recommend a sealer for this type of leak? I believe it is the timing cover
and not the head gasket because I am not losing any coolant at all.
Amber O'Connell: Work for a gmc envoy??
Taylor Smart: found this video extremely helpful, was doing my own research and found
that a few symptom of a faulty head gasket could be low/irregular idle as
well as decrease in engine power and acceleration, which my car has
presented me in the past week. Ive had an overheating problem consisting of
an initial hole in the heater hose which was leaking. i have replaced the
heater hose and eventually bypassed it altogether through the heater valve,
pulled the thermostat (hot weather in CA), replaced radiator hoses and also
got a brand new radiator. for a while but i did notice a wet spot under my
car this morning after driving it all weekend so I'm hoping it is an
external leak that i now need to locate? Or would you recommend getting a
pressure test to confirm that it is the head gasket?
stclemmons1969: Great explanation of what headgasket leak is. Thanks.
Whitney Maiava: can this be used on bmw z4
ellefly91: I have a 2002 Nissan maxima and its not overheating but there is white
smoke coming from the tail pipe. i would like to know how to mix the the
k&w product with the water
Lisa Walls: I have a 1991Mazda Miata convertible that has blown a head gasket. white
smoke and all the other symptoms of a blown head gasket. when it happened
just so happened a Mechanic stopped to offer assistance and he even gave it
a once over to help solve whatever problem I was having...he said it was a
head gasket also. so,......here I am, blown head gasket and am trying to
figure out the best and cheapest route to go. what do you recommend? I've
seen different sealant product's but am really confused. can you give a
poor girl any advice?
signed, all alone in MO.
P.S. My name is Lisa and my dad who passed away 2 yrs ago used to help me
with these kinda problem's., but I have no family left and being that I'm a
blonde, middle aged woman, I just don't wanna be taken advantage of. YA
kNOW...... THANK'S for any advice. I have no were else to turn but Youtube
and Google. HELP ME PLEASE!!!!
mupvh: Hey Austin. This is Paul. Just wanted to stop by and thank you so much for
saving me about $1,500 on my head gasket repair. I did EXACTLY what you
said and it worked beautifully. No more misfiring or white smoke coming out
of the exhaust. I'm at the 500 mile mark now and about to drain and flush
the product(block sealer). However, my question to you is: Since I live in
South Florida and cold days are very very rare here, after draining the
product, can I just go ahead and fill it up with distilled water or should
I still use 50/50 coolant and why? Please help me learn. Thanks again for
all your help buddy. I'll be waiting on your reply.
James De Mar: It will take me well over a month to go 500 miles. Can you suggest a length
of time, such as two or three weeks?
Dave F: The metal ring doesn't go around the piston. The piston rinds do. The ring
on the head gasket ring is compressed between the head and the block.
Vincent Nguyen: Definitely helped! thank you for a wonderful video sir
Montana Michniak: Hello, I recently purchased a used 2002 Mercedes C230 Kompressor. It is
currently diagnosed with a Head Gasket leak, which is mixing oil and
coolant. Before being diagnosed with the head gasket it was diagnosed with
a small oil leak and I was able to take a 5 hour trip to New York there and
back (Total of 10 hours driven). On the way back from NYC the car started
putting up a sign of "Low Coolant." I took it to the MErcedes Dealer the
next day and they diagnosed the head gasket problem. The estimate is
$1,600. I am currently a 3rd year college student and have no option of
paying this estimate and I am trying to find another way to fix this
problem. I have read a lot about Steel Seal and other Sealants and feel
like it is a hit or miss product. Would you happen to have ANY
recommendations? I am in dire need of help. Thank You!
LearningZone: Awesome explanation dear mate. Great video. It went a little funny @0:55
Where your arm was pointing like a rooster. lol. Regards,
Freeman Littlerood: The K&W Head Gasket Repair with "Nanotechnology" has worked to stop my head
gasket leak in my old Toyota Previa van. A head gasket leak functionally
"totaled" the van which was not worth a lot, so I figured it was worth the
risk. Do not know what all it may have clogged up in the cooling system,
but bottom line it worked. If my van was worth $10k or something I would
not have tried it, but this will extend the life of my van and keep it
working for a while I hope. It cost $20 at Walmart. I first tried K & W's
older version in the orange can (for $9 at Autozone), this appeared to be
working but my van overheated a little and it sprung a smaller leak. But
now the larger green bottle with micro particles seems to have done the
job. For you purists who insist on a proper head gasket replacement,
please forgive us poor mongrel slobs who can only afford to pay $20 on a
$1000 vehicle rather than $500-$3000 to a mechanic. I know this cuts into
the mechanic's livelihood, and I feel for him, but.... For some of us it's
either this stuff, or just buy another car of equal value (also near the
end of its life in some capacity). By the way, I blended the advice of the
"trustmymechanic.com" video-- Best Head Gasket Sealer For Headgasket Leaks
(using the orange K & W can) with the actual instructions on the K & W
green bottle (which I believe is the same as those on the orange can).
Essentially, he recommends not draining the stopleak fluid after 30
minutes, but rather leaving it in for 500 miles so the metal flakes can
melt and adhere to the head gasket area and anywhere else there may be
leaks. I drove my van for as much of the 500 miles as I could that he
recommends (winter was approaching, so I drained it at about 300 miles). I
let it dry empty for over 12 hours (as instructed by the green bottle).
Then put the 50/50 antifreeze mixture back it. All appears well. No
leaks. No reduction in my van's performance. The van lives for another
season--no doubt a little crippled, but functioning. Those made of money,
please skip these steps and buy a brand new luxury car. Or if you are
sleeping with a mechanic, maybe he'll give you a head gasket job for $100.
These are pretty much your choices.
CORVAIRWILD: I used K&W nano in my wife's '95 diesel 6.5 Sub w 260k. It was using 1 qt
every couple hundred miles. since winter was coming, and a rebuild is
thousands of $$$, I tried the K&W, followed directions to a T, and water
consumption is way down and engine rumble/misfire is gone. It's been about
4k, so far so good. I made a video of the entire procedure, it may show up
beside yours. Thanks for the nice video, well explained
Dave F: K&W Block seal has always worked very well for me. IF DONE RITE, should
work every time. Just as long as the engine will still start and run.
Misfire or not
Nj Medic: Any difference in your process with the newer "nano". Since the nano has no
metal in it, do you really want to run it for 500 miles, especially since
the bottle says don't drive at all, just idle. Not to mention 500 miles on
a car running on 3 of 4 is almost painful, may take you years just to get
where you are going :-)
PZtheDrummer: So I replaced thermostat radiator plus water pump and still losing coolant
I believe it's internal I see white smoke not a lot but def some also when
I fill coolant and check a week later it looks like coffee the symptoms so
sign of warped gasket. This is a 94 ford ranger with 214k on it is k&w ok
Vedric Jordan: Hi, I have a 2002 dodge stratus coupe SE, 6 cyl my exhaust started to shoot
white smoke and my car acts like it want to turn off, i stopped driving due
to being worried. my mechanic said it is a blown head gasket because when i
drove the car began to smoke due to gasket leaking oil as well, I noticed
there are several brands to engine block seal k&w, which do you think would
be best for me. the mechanic said blue devil but i would love to try this
one. what is the general price range so i can know which one to buy. Thank
you sorry for the long question.
Paul Deebo: Will k&w liquid do anything to the thermostat if I dont remove it
Jesse Mcnab: Help, my 05 dodge Dakota 4.7L v8 just started to over heat yesterday,
noticed it when in idle waiting in drive through line, after I started back
home the motor cooled back off, now today it has gotten worst to the point
where the coolant completely drained from the reservoir. I don't see any
white smoke, the oil is normal colored and I even took the radiator cap
off, filled the reservoir and cranked the motor when cold and nothing
spilled out of the overflow. So confused on what it might be.
