1995 Chevy Lumina-We put stop leak to prevent coolant from leaking out, the radiator seemed to build up pressure and now the car doesn't run at all, any ideas?
OK..you put some kind of product in the radiator to stop a leak ..leak from where? The radiator itself? Then you tested it with a air pump pressurizer? It was running before, but had a leak, but never started after you put the product in. Let me know if I have it right so far please....
Any product outside of antifreeze is what you get ...if your trying to stop a leak then there are other water system of the cooling system and that cheap fix will cause you more damage than you want to get into and will cost you new parts to get rid of it this is not a guess I worked at ADAMS MOTOR COMPANY as a heating and cooling technician.
