shocked it worked
my head was leaking oil into the coolant/radiator , and overflow bottle , it was full of it , i drained the radiator, plug at bottom realised the rad was saturated with oil as i could not fill it up , i changed the rad , easy job, i have no experience, did as it said on my 2007 civic ,i was shocked but it really worked, my wife has a client he said his car has done 20k since and still going, you must clean out rad and use a flush for coolant system ,it goes in the rad , gl

Didn’t work
Didn’t work, this was an expensive project, I should have put the money towards getting the leak fixed (which I done) rather than waste money on this product that failed to deliver.
