I went under to change my oil and saw there was a bit of coolant residue on my engine splash guard as well as on the driver side of my pan. I looked a bit more to see some coming down the driver side of my engine, but wasn’t able to see the source from where I was looking.It wasn’t enough to ever drip cause I never see any leaks. I do want to get this fixed ASAP though because I hate when things aren’t how they should be. Please let me know if you have any ideas, picture is attached.

Coolant leak down driver side of my engine. Any ideas where source may be?

 

There is a weep hole on the side of the block next to the thermostat. Get an inspection mirror and see if that's where it's coming from, if so then you need a new water pump. It's designed to weep when it's worn out to pet you know it needs replacing.

There are also coolant lines for the oil cooler in that area though so you definitely need to use an inspection mirror to find out exactly where it's coming from.

Use a flashlight and shine it directly on the mirror and the light will reflect off onto the surface you're trying to inspect.
