Notice coolant leaking when I warmed my car in the garage. It seems to happen either during warmup, shutting off after driving around a while, etc. The leak location is on passenger front by the oil filter (see pics). Took to firestone (the only place open on a Sunday) and they couldn't find ANY leak during a compression test for 30 mins. Checked the revsivor hose and nothing was draining from there. Any idea where it might be coming from? Could this be a sign of a bad water pump?

 

Yup.

 

Is it coming from the bottom of the timing cover?

 

You can rent a pressure tester for the cooling system. A few psi in there will make it leak and should be easier to find.

 

Yes water pump... most likely the weep hole...

 

Yeah, that was done by Firestone. No leaks. And they checked all the hoses, they were all tight. The guy said that general area is where the resevoir hose is and water pump. It's a phantom leak...right after I drove back home (15 mins drive) and parked, started slow drip. Turned off car, it was still doing it. After a few while, it stopped.

 

Looks like your water pump.

 

Want to make sure the pressure test wont show a leak from water pump?

 

If your only leaking when hot, it may not when you do a cold pressure test. But if its already been pressure tested, then I agree with everybody else on the water pump.

 

It will should a leak but a very slow leak plus the timing covers on so you wont see it.

 

Thanks everyone for helping a noob. It was the water pump and have now been taken care of
