Q: Coolant leak

asked by on February 10, 2016

My car has a coolant leak.

Hello! The easiest way to locate a coolant leak is to have the cooling system pressure tested, which can be performed when the engine is cold. The most likely failed component would be the coolant pump. It’s usually good practice to change out the thermostat at the same time. Once the repair is verified by pressure testing the system again, coolant can be added, and the cooling system can be bled. The car may have to be jacked-up to inspect for coolant leakson the underside. I would recommend enlisting the aid of a mechanic, such as one from YourMechanic.
