Description & Specifications

Wynn's Cooling System Stop Leak sealant is designed for minor leaks in the radiator, cooling system and heating system of petrol, diesel and LPG engines. It also seals leaks from the cylinder head gasket and can be used preventively. It also has anti-corrosion properties.

It is compatible with all antifreeze and coolant fluids, including OAT technology fluids. Its formula does not damage hoses, gaskets or other system components and is designed to prevent blockage of radiator passages and temperature sensors. To use, check the coolant level, start the engine with the heater set to maximum and, after shaking the product thoroughly, pour the entire contents into the system through the radiator filler cap or expansion tank. Then close the system and run the engine for 5–10 minutes. Top up with antifreeze if necessary. If the system is very dirty, it is recommended that it be cleaned beforehand.
