STP GST96300EN06 Radiator Sealer Permanently Seals Leaks Treatment (300 Ml)

Was told to replace the radiator. But it’s been almost a year and the leaks are all fixed

Leakage reduced to a smaller amount of coolant but not stopped completely

I have a quiet extended crack on my radiator’s connection and I used to add liquid everyday, this product closed the crack 99%! Very happy with the result!

Adding this in the coolant reservoir fixed my Chevy’s issue..

I added it to my car coolent water and It really works

Didn't work on my leaking GX 460 radiator. Was a relatively small leak as well

Used it with different vehicles and it worked as it should
