STP Radiator Sealer

Radiator Seal. Effectively stops most leaks in the cooling system for a permanent seal. Does not damage gaskets, hoses or metal. Protects against rust and deposits inside the cooling system.

Instructions for use

1. Run the engine until the coolant is warm.

2. Shake the bottle well and pour the entire contents of the bottle into the radiator. One bottle is sufficient for cooling systems up to 14 liters.

3. If the product is poured into the expansion tank, ensure that it all enters the cooling system and does not remain in the expansion tank.

4. Run the engine for approximately 10 minutes with the cabin heater on, allowing the product to cure.
