  • Remove information such as make, year or model.
  • Can't find the part you are looking for? Contact us and we'll find it for you!


Your car's cooling system is responsible for regulating the temperature under your hood. Since your engines go through about 40,000 explosions per minute, keeping the car cool enough will keep the engines efficient.

The process includes the use of coolants, thermostat, and the regulator. Coolants absorb heat from the cylinder block through water pumps, then would pass through the thermostat and the regulator.

Coolants don't need maintenance, but they should be replaced every 120,000 miles. Of course, this would depend on your driving habits, conditions, and the vehicle's owner's manual.

Meanwhile, hoses and clams used in the coolant systems vary in shapes and sizes.
