I get so many emails each day and the majority of them involve head gasket leak problems. Now, before you just run out and use the sealer I am going to suggest to you below in my video I want you to MAKE DARN SURE YOU HAVE A HEAD GASKET LEAK FIRST
I would bet that over 50% of the people I talk to that have been told they have a blown head gasket actually do not. Their mechanic has not done a proper “cooling system pressure test” which should be FIRST, so they just assume the worst and blame it on the gasket.
Not a bad gig actually, a typical head gasket repair can cost $1000 minimum. So during the repair the mechanic will most likely stumble upon the original problem and repair it but it has cost you $1000 in the process.
I made this video which hopefully will help you determine if your problem is internal inside the engine or external like a water pump leak. After you watch the video below and you still think you have an headgasket leak, then try my suggested sealer I talk about. I will put my instructions below the video for you.
Ok, so hopefully you watched my video above and you are sure you have an internal coolant leak in the engine. If so, then try this yourself and see if it helps.
Buy a can of K&W Engine Block Sealer additive (Nanotechnology is the new version and works just as well)
1. You must drain out all coolant from the radiator first
2. Take a bucket and mix the sealer and tap water together
3. Add the contents to the radiator and top off with tap water only
4. Drive the vehicle for 500 miles, not at one time but soon
5. Drain out the sealer and go back with the coolant water mix
The repair, if it can find the torn area of the gasket should be permanent.
You will not have any protection from freezing or boil over during the 500 miles, so make sure you protect your engine.
I also do not remove the spark plugs or thermostat as the can suggests. That is all there is to it and we have been using it that way for many years with a 80% success rate or so.
Watch this video to learn about engine overheating and how you can determine the problems yourself.
