Why is my coolant reservoir draining so fast?

This can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch. In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator.

What causes coolant to leak from overflow?

Coolant, or antifreeze, is essential to regulating the temperature of your vehicle. It’s also extremely toxic and designed to stay inside a closed system. If you’re seeing an overflow, it could be due to a radiator cap, thermostat, water pump, or radiator malfunction.

A small amount of coolant in the tube overflow will run down to the expansion tank if below the radiator cap. Type 2 – Pressure cap is on the expansion tank and the radiator cap is a plane cap that seals on the top of the radiator above the overflow pipe.
