The third leading cause of vehicle breakdown is caused by cooling system failure.

The function of the vehicle radiator coolant is to reduce the temperature in the vehicle's engine. Coolant protects the vehicle from overheating and freezing. Coolant allows the vehicle to operate at high temperatures and low temperatures.

Over a period of time as operating temperatures fluctuate in the vehicles engine, coolant deteriorates forming harmful deposits. These deposits build up in the vehicle's radiator and eventually restrict the flow of coolant fluid through the vehicle's engine, which leads to system failure.

A complete cooling system flush when using ZAK Products radiator products will clean and remove harmful scale deposits and rust. New, clean replacement coolant that meets vehicle manufacturer's specifications is then added to the vehicle.
