Q: Antifreeze leak

asked by on

I have antifreeze leaking out from underneath the passenger's side, but the antifreeze container is still full.

A: An antifreeze leak may not affect the level...

An antifreeze leak may not affect the level in the overflow bottle. The leak may be the heater core or radiator leaking; a pressure test is typically used to locate the leak. I recommend having a mechanic, such as one from YourMechanic, come by and perform a thorough inspection to find the find and repair the leak.
