    Works less is more !

    It actually worked I had a small intake leak causing my #4 cylinder to eat antifreeze trucks worn out 200k+ not worth fixing right but wasn't a bad leak but enough to foul plugs and cause radiator to run low after few months . So I put a quarter bottle in and it stopped the leak into the combustion chamber going on 3 months now !! Add it in small amounts until your leak stops u don't want more than u need the stuff hardens like glass!!

    This will do the job.

    This stuff works better than products that cost 5 times as much. Sealed the antifreeze leak the first time where others had failed. Don't over look this product because of the lower cost.

    Cooling system sealant. Works great.

    I had a leak I couldn’t find. I haven’t had a leak since I put it in.
