Coolant Leak

    So I have a coolant leak on the wife's Tahoe. It looks like it's coming from the very bottom corner of the passenger side front engine cover where it meets up with the oil pan. Any one on here know what that's all about? Are there a couple freeze plugs up behind the engine cover that could be causing this? What else might be up in there causing this leak. It doesn't look to be coming from up above that juncture, like where the heater hoses go into the engine or from the water pump. Engine is a 5.3 in a 2001 Tahoe with 90K on it. Any help from the GM Techs on here would be great. Thanks for your time.

    Well, it's really hard to say without looking at it but I would think either a heater hose, bottom radiator hose or water pump. I really haven't heard of freeze plugs going out on those but I would bet it's a hose or water pump. Good luck, I hope this helps.

    Passenger side near the oil pan is the bottom side of the water pump. The thermostat gasket is also near there.
