    Your engine is cooled by a mix of ethylene glycol and water, circulated through a radiator by a belt-driven pump. Proper maintenance of your Subaru cooling system is critical to keeping your engine happy and healthy! Browse our Subaru cooling system parts below to find exactly what you need for your WRX, STI, or BRZ, from radiator hoses to water pumps, radiator caps to thermostats.

    If you're looking for coolant, that's over in the Fluids and Cleaners section.
