didnt work
Sam H.✓ Verified Purchase•September 6, 2017
didn't fix my leaking radiator even though my car could idle for 15 minutes without overheating.
Seemed to fix small coolant leak on VW Vanagon.

Had a small leak (few ounces a day when driving) in my 1984 VW Vanagon. Did not know if it was head gasket or heater core. Read online through a VW site that this might stop an antifreeze leak on older vw vanagons. Poured it into the overflow tank and so far it seems to have worked. If so much cheaper fix than I expected.

the product most likely works well, but my heads were too warped
Car is in great shape, but not worth a $2500 head gasket ...

Had a small external coolant leak on a '98 BMW 328is. Car is in great shape, but not worth a $2500 head gasket repair. Tried this and its been two weeks with no sign of leak. Cautiously optimistic!
It works
