    Worked for blown head gaskets in 3.4L GM engine
    I tried this in my 2000 Chevrolet Monte Carlo...3.4L V6 engine. If you know anything about GM cars, you know that the 3.4L engine is a lemon. Inlet manifold gasket failed after 100k, then 10k later the head gaskets failed. I had the inlet manifold gasket changed, but I didn't want to do the job all over again for the head gaskets. So I tried this instead. So far I've driven 5k additional miles, no issues. It really worked. I noticed a definite improvement after putting it in the radiator. If it starts giving me problems again, I'll likely use another bottle.
