Cooling System Flusher

Quick & efficient cooling system flushing

To ensure the optimum operation of your cooling system it is important to secure that the coolant is not polluted with abrasive particles and foreign materials. This is not a problem with JWL Cooling System Flusher. With the cooling system flusher you can flush the whole system without use of solvents and harsh chemicals. It uses a combination of water and compressed air, which increases the water pressure without damaging the surfaces.
The cooling system flusher is assembled with a connection (1/2” /ø13mm) that fits the most common water couplings. We recommend that a water coupling with adjusting valve is used in order to be able to adjust or switch of the water without going to the tap.

Instruction: To flush the cooling system properly, insert the stepped gun nozzle of the JWL cooling system flusher in the hose suited for the flush job. Flush until the outflow that runs through the radiator, engine block and heater core is clear. To prevent damages, make sure there is free passage through the cooling system before flushing.

CAUTION: Extreme care should be taken when flushing cooling systems in poor condition.
