What Is A Coolant Reservoir?

Coolant is vital to ensure your engine does not overheat. The coolant circulates throughout to carry heat towards the radiator, where the hot air can then be dispersed. As the highly variable temperatures expand and contract the systems and the fluid, there needs to be a place for coolant to be stored when the system is pressurized. Enter the coolant reservoir - that’s where the coolant is stored. Moved through a surge tank hose, coolant can be taken or added back to the system based on temperature, with excess being stored in an overflow tank.

Common Signs And Symptoms That You Need to Replace A Coolant Reservoir

• Engine is overheating
