Subaru WRX STI Coolant Reservoir

The Coolant Reservoir in Subaru WRX STI automobiles is a critical component of the pulling-coolant framework that is mounted to ensure that no coolant leaks and disruptive air invades its system. There are two main types of Coolant Reservoirs used in these vehicles: over-flow tank system and expansion tank system. The overflow system contains the pressure cap mounted on the radiator whereas the expansion system has the cap mounted directly on the tank. Both systems' tasks include regulating correct coolant levels and ensuring that air does not become a problem in the cooling system. Maintenance checks on the Coolant Reservoir should be conducted with recommendations of replacing or repairing in case of inefficiency over a given period of time.
