Bluecol Radiator Sealer 500ml 500ml

Bluecol Radiator Sealer is a fast acting repair for leaking radiators. It also stays active to seal further leaks and contains rust inhibitors to help prolong the life of radiators. Bluecol Radiator Sealer will not harm radiators, hoses or gaskets and it mixes with all types of antifreeze already in the cooling system. Directions for use: Run the engine for a short time until water is warm. Beware of pressure in the system when removing cap. Check the water in the cooling system is visible. Shake bottle well and slowly pour the Radiator Sealer into the radiator. Run the engine for a few minutes to allows the sealer to harden. Note: The 500ml bottle is sufficient for two treatments for cooling systems of up to 12 litres capacity. Not recommended for Rover 825/827.
