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
OldskolFan: You should recommend only using distilled water because regular water can
leave calcium deposits?
dtv4334: my 460 v8 78 lincoln engine smokes white and shakes when i first start it.
after like 10 mins it runs fine. do you think its the head gasket? it is
not leaking coolant
OldskolFan: My car is leaking coolant and I was told to replace the coolant temp
sensor. But they want to do a valve cover gasket and intake manifold gasket
replacement as well? Aren't those for oil leaks? I know I have oil leaks
but will sealing those help my overheating and leakage problems? I have
a new water pump and radiator but sill leaking coolant?
Paul Deebo: Will k&w liquid do anything to the thermostat if I dont remove it
Lindsey B: Hello, I have a 2000 Oldsmobile intrigue and the head gasket is blown. When
the problem first occurred I took it to a mechanic and he checked my hoses
and changed my thermostat (after we changed it we seen it was bad, so glad
we did change it). After doing that the car was still running extremely
hot, and also began leaking coolant and water. He told me it was the head
gasket. I bought some K&W sealant that your taking about in the video
however, I have yet to use it. I no longer have the mechanic, doo I would
need to do it myself and well the instructions call for what seems like a
lot of work. My questions are, 1. There is no radiator cap in the front, so
do I drain from the coolant reservoir? 2. Do I need to take the thermostat
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.
saidee renee: Thanks for the video! I was unsure about additives and block sealers and
what not. but that made up my mind. gonna give K&W a try. We have a 1999
grand am it's a good little car in great condition that we bought as a
spare being my truck gets such terrible mileage, everyone in the family
likes it so it is actually used daily, I'm positive at this point it's the
head or gasket. I've changed thermostat, reservoir cap, checked for
external leaks by pulling it on ramps and letting it idle about an hour,
not a single drop on the floor, will hold pressure all night and we DO have
to add coolant daily as long as you add coolant it doesn't overheat just
getting rather expensive, checked the dipstick several times and not any
sign of water but today i took the oil filler cap off and sure enough the
cap had that same ol foamy whitish build up I've seen before. normally I'd
just bite the bullet and have the gasket and the head work done it just
doesn't seem very cost effective to put $1500 in a car that's only worth
about $1500 lol so I'm gonna try the sealer today or tomorrow keep our
fingers crossed and let you know it goes. thanks again!
Dana Stamey: Austin,
I have a 2000 Subaru Forester...I've been having to put 1-2 quarts of water
every time I drive 50 to 100 miles...don't see any water on ground when
driving...it recently started overheating...with just a little white smoke
out the tailpipe every now and then...it's been overheating some...thought
it was the thermostat...got one bolt out of thermostat housing and couldn't
get other one out...and decided to wait on thermostat replacement...also no
water on oil stick...my friend also done a Burp test and it bubbled a
lot...he also thinks it could be the head gasket..."where do you buy the K
& W Block Repair"...the one you were talking about that has the copper in
it? Please help...do you think thermostat or head gasket...can't afford a
head gasket job since I'm just working part time...Thank you!
Arturo Pavon: Thank's for the info great tips...
john whitelow: I got a 2002 Buick Rendezvous. New Spectra Premium/Radiator, New Duralast
Thermostat, New A/C Condensor, New Upper and Lower Hoses and Clamps. Still
has Cooling issue... Tested water pump when replacing radiator and seemed
to be working. Now it does have white smoke coming out the tailpipe and the
check engine light came on.
Orlando Ferrassoli: I have a Dodge Grand Caravan 2003 that overheated, now lost a lot of its
original power. There is no white smoke coming out of the tail pipe, but
just what it looks like water. My mechanic did a quick check and saw that
there's fumes coming into the radiator and it won't pass the smog test
(that I need right now). He said it is very likely a blown head gasket.
But, could it be a crack in the engine too? I have some oil on the floor
too. Would K&W work for both engine (if it is) as well as the head gasket.
I am willing to try, but would like to hear from you first. Thanks :)
Huud Warsama: Had a head gasket leak a week ago, followed your instructions and it seems
to be working fine so far. Two questions, when I drained out the radiator
there was still some antifreeze residue in the reservoir pump, but it was a
very small amount, could it affect the sealer? And am I better off doing
this in comparison to just replacing the head gasket which could just very
well blow again? Thanks.
SolarUmbra: I have a subaru with an external headgasket leak. will this work well for
me? if so, how long will it hold for?
bluecanoe17: Two issues:
Many Silverado trucks had heads cast by 'Castech' that have porosity
failures, resulting in coolant leaks into oil or combustion chamber, or
both. Will this product repair that problem as if it were a standard blown
head gasket leak?
ALSO, Is there a capacity issue with this product? Meaning, if I am putting
it in an 8 cylinder engine, which has a much larger volume of total coolant
than a 4 or 6 cylinder, should I use more than one jar of the K&W?
I have gradual coolant loss on a 6.0L 2004 2500HD. No oil/water mix. Some
white smoke in exhaust. Should I try this product, or just get new heads?
moises lopez: Hi ..will the radiator gets blocked with that product ?.....Thank You.
Jayanath gampalage: I have Toyota Vitz / Yaris SCP10 1.0L (Year 2000) hatch back. Recently I
flushed the radiator and added coolant and water. Few weeks ago it showed
the Heat Bulb (Blinked) and I stopped the car and checked the coolant
level, and it was dropped. I filled with water and came home went to
mechanic and it shows bubbles in radiator coolant. There is no sign of miss
or compression loss.. but small / Tiny bubbles like foam pops out from the
radiator coolant. Mechanic said there is a head gasket leak. Could u
please give me some advice
Ken Tseng: Awesome video. Thanks for sharing.
May I ask : I never overheat my 95 Nissan Maxima , I only drive like 3~4
miles from school to home, and local use less than 50 mile per month, I
would say. But about two months ago, it starts to leak coolant somewhere,
so, I have to add coolant + water like a half gallon every 2,3 days. This
morning, my car started to act up. Engine idle gets very low, but still
stable @ around 500 RPM. I don't see any white smoke coming up, but I can
see the oil is muddy color, like brown, or coffee color actually. Do you
think I have a blown gasket? and does the K&W would work on my case?
Like you say, the mechanic wants to charge me 1,400 for blown gasket,
Thank you in advance for your answer.
Jason Henriques: great explanation, i just had a question regarding my 97 Mitsubishi eclipse
gst i have a problem with my head gasket theres oil leaking along the top
to the bottom and theres spots on the floor and the engine light doesnt
determin anything wrong with the car can you help me out
Frist Last: Great Vid. Wish you were in Australia!
King Burns: My 2002 malibu doesn't smokes it just runs hot. But its the heads. Could
blue devil fix the leak.
CrzyNV Miles: How would you rate their pour and go product? Is it a just as good you
Karen Admire: I would like to know if you remove the thermostat when you use your
007secretspy: Thank you the informative video.
My 2001 Nissan Xterra 6 cylinder seems to have some symptoms of a head
gasket leak but not at the same time. When I start my car and start
increasing the RPMs, there is a little white smoke and water coming out of
the tailpipe. This only happens for a few minutes and then it does away. I
checked my oil dipstick and there is no milky substance. My engine seems to
overheat sometimes. It's rather inconsistent. Today it started to increase
in temperature after driving on the freeway for 45 minutes (no traffic) and
wouldn't go down even when I wasn't idle. There was no steam/smoke coming
from under the hood. When I stopped the car I could hear boiling sounds
coming for the radiator. (Radiator and resorvior we're NOT low on coolant).
Again, the car temp was completely normal for the first 45 minutes or so of
freeway driving then all of sudden the temperature shot up. I'm getting
mixed signals from my car.
mike p: You forgot to mention; exactly how much tap water do you mix with the
engine block sealer? I don't want to mix too little or too much water.
Geo: will it work as a preventative fix.. Some people suggest using Steel Leak
as preventative measure to extend the life of a head gasket, I wonder if
this will do the same thing..
MisterNifty: It is already steam before it leaks into the cylinder or, being water is
incompressible, it would ruin the engine. Ditto for the Anti-freeze. .
Konnor Rice: I have a question about our air conditioner. it only works whenever we are
driving and it takes forever to get cool. We have tried free-on and it
doesn't work. whenever the compressor kicks in it makes the engine idle
rough... do you have any ideas?
Tamara Rowe: I am wondering if this is what my problem is...I am losing coolant from the
overflow reservoir. There are no issues when it's pressure tested...The
water pump, clutch fan and thermostat have been replaced.
Rich Grome: I have an '06 Hummer H3 5 Cyl.
My mechanic has now suggested I might have a head gasket leak after we
replaced the radiator and thermostat twice, the water pump, the serpentine
belt & tensioner and the fan clutch too all to get the engine temp to
normal as it was running hot. With the A/C on it was pegged at 3/4's. If I
turn the heat on it goes back to normal. On warm weather days it goes past
the centerline but stays below 3/4's. There is no outward coolant leaks,
and no coolant in my oil. He only charged me for the 1st radiator and
thermostat and did the rest of the work for free since he was embarrassed
for not figuring out what was wrong sooner. Now he says a head gasket job
is about $1700.00, he instead recommends I just get a new engine (rebuilt)
since my engine has 170K on it anyways. An engine replacement he says will
cost me about $3200. Should I try this sealant out first? Any
advice/thoughts on the matter I would appreciate.
Rajan Haridasan: Hi, please advice if there is any other product other than K&W that works
.. (ford focus 2002) also I have had my engine gauge in the car heat after
my radiator was re-done and a new thermostat put in .. Now the heat of the
engine in the dashboard reached the red mark and I shut down the engine and
waited till the temperature came down. When I opened my bonnet the coolant
tank was boiling. Kindly help ..
Danny Rorabaugh: TrustMyMechanic.com just wondering.. I had to replace my rad iator. So
Ipurch ased one, installed it, and burped the system. Now the temperature
would go up, down, up, down.. and when I shut the truck off it bubbles out
of the coolant reservoir. So I replaced the radiator cap, thermostat, and
water pump. Temperature is now running correctly. Heat runs like it's
supposed to. But still having bubbling issues. Bubbling is not near as bad
as what it was. Pressure tested system, and tested fine. So.. I guess next
step is to have the it chemical tested for exhaust gas in the coolant? If
it is a head gasket, will running the K&W water mix seal up water ports in
the heads? Just not sure about it. But I'm also not made of lots of cash to
fix the gasket at this time as well. Any info would be much appreciated!
mcarino98: My radiator hoses gets really hard when engine gets hot. my engine doesnt
overheat but bubbles comes out of radiator during cold start. No coolant on
oil and vice versa,no coolant on tranny fluid as well.coolant looks
clean.my exhaust is kinda moist too even after driving. Do I have a blown
TRUTH4U2NO: Alright so dont follow the manufacturers directions on bottle. So you you
answered the question are you a rep for the product...I gather not. Sorry I
think Im gonna follow the directions.
saidee renee: by the way do you use the same procedure you spoke of when using the
Arturo Pavon: HI great video I have a 95 saturn i change my water pump a termostat and
its still over heating ha ve a new radiator what can it be if you could
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
eladio beltran: Thanks I find the instructions !
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.
SickDuck: I have a 98 ford explorer I have white smoke coming from my exhaust pipe. I
have to add coolant almost every other week. I'm not sure about the head
gasket and I don't think I have any over heating problems. Should I try
fatwan munaser: Hello,
Thank you for the video
Jeep Cherokee Loredo 2005
Cant say that I did much in terms of maintanance besides oil change and
I know I seriously need to learn more to keep my vehicle maintained.
1.Coolant flush last year.
2.1 Month ago my car overheated and the waterpump was making noise and
Took to the Mechanic and he replaced the waterpump since it was bad.
He took the radiator cap off and seen the coolant was "caked up" on the cap.
He mentioned that the caking up of the coolant is probably due to the
radiator is cloged with 'gunk'.
3.After the water pump replacement I have had no Overheat problems it
looked like my overheating was indeed due to
the waterpump since I have no overheating now over a month with no problems.
4.I recently noticed that in the morning (after the vehicle has been
sitting overnight) when I start the vehicle that white smoke appears from
After driving for a few minutes there is NO MORE white smoke at all.
5.I decided to take it to a mechanic to get it checked out. He did a block
test and after a few minutes the color remained blue.
After a few more minutes it started changing to a bluish green color with a
hint of yellow. He mentioned that this means that there
is a blown head gasket.
Side note, with the radiator cap off and engined cooled down a little the
machanic started the car.
The coolant remained put and DID NOT overflow. Suddenly after about 5-10
minutes the coolant began bubbling and
overflowing. Again note radiator cap was off the whole time.
question: Is this suppose to happen when the vehicle gets hot enough that
the coolant will bubble up and start overflowing?
Or could this also be a problem? Please let me know your thoughts.
1.I am confused how this is a blown head gasket for the follwing reasons:
-No Over heating at all
-coolant appears to be full
-White smoke only when starting the car in the moring when the vehicle has
be sitting overnight. Also White smoke clears up after a few minutes of
Does this sound like a blown head gasket? If so, will the sealant you
mentioned in your video work for this case?
Your details are much appreciated since I don't know a lot about cars.
2.How do I have caking up in my coolant on radiator cap if I flushed the
system last year?
3.How can I tell if the radiator is bad and needs to be replaced vs.
radiator just needs to be flushed?
Thank you in advance I learned a lot from your videos and hope to learn
Jeremy Damsgard: I have a 2000 Cherokee with the 4.0L. I'm pretty sure it has the 0331
cylinder head crack issue as the coolant is magically disappearing from the
overflow tank. I have a bottle of the K&W in the green plastic bottle.
1) The bottle says to simply add it to the radiator. Should I disregard and
follow your instructions even though it is a different product than the one
2) Have you tried this stuff on any of the Jeeps with this issue?
3) Any further advice?
Thanks in advance!
theundergroundhits: so does nano technology also apply the 500 mile theory as well?..
Demetrius Cole: Mix it with what?????
allsaw31: I got my radiation replaced on my 06 equinox but still having an
overheating problem. And coolant is leaking from overflow hose. Would you
recommend the k&w block seal for this problem?
cynthia camacho: Hi. I have a 2005 Pontiac vibe. I went in for an oil change and they took
me to my car while up in the air and showed me I have an oil leak on the
back of my engine. They said there was no milky look in my oil but said i
may have a head gasket leak. I don't recall overheating my car and i don't
have to put water in it very often and there is no white smoke
Ashmoh91: I have an 89. Honda civic and I do not have milky oil or the bubbling in
the radiator I do how ever have white smoke. And I little bit of roughness
to the engine. I am so concerned that any sealant product will damage my
car. I have had mechanic friends tell my to kljust replace the gasket but I
do not have the money right now. I truly need to know that this or any
other product will not clog or ruin anything else be for I use it.
eric beauchamp: This video has been quite helpful, thanks! My 04 focus is on its' last leg
anyway so I don't mind if I mess up a few parts BUT what is the
significance of removing the spark plugs and/or thermostat or leaving them
