Generally
Cooling tablets that do not stop circulation but only seal small leaks in radiators, heat packs and hoses. Great little tablets made by GM.
You do not need to empty the system or drain the glycol. Just loosen the radiator cap and drop them into the radiator and drive. The picture shows a pack of 6 tablets, sometimes the pack contains 5 tablets. We will send the one we have in stock at the moment.
