Don't stinge and be genrous
A lot of people say it does not work. I use a chevy 2007 and it worked great for me. I had to buy this 3 times.1st time, full bottle used in 1 go, worked amazing. Went to mechanic, got a radiator flush and the leak came back up.2nd time, used bottle 3 times cuz it was not sealing, did not work and leak continued. No mechanic involved3rd time, got the bottle, used the full bottle in one go and it worked again. No mechanic involvedMoral of story, use the entire content of the bottle in 1 go. It will work, if it doesn't, the leak is bigger than imagined.

Really seals any leakages in the cooling system
If you see bubbles coming in your auxiliary coolant tank and engine keeps heating up, recommend this product to fix it.
