QuestionQUESTION: My GF has a 2001 durango and the coolant reservoir keeps going empty.
I checked under the truck one day for a leak. I saw fresh green coolant leaking off the frame since I just filled the reservoir.I looked and looked and could not find the source of the leak it seemed to be coming from the passenger side of the engine leaking onto the frame.I thought it might be a hole in the coolant reservoir and my next step is to take the reservoir off and check for leaks. The reservoir goes empty after using the A/C, got any idea ?
ANSWER: Hi Rich,
I am not familiar with which engine you might have, nor therefor of the paths of the hoses that connect all the parts of the cooling system. I can only suggest that you consider gravity as the force that is causing coolant to fall from a higher leak point straight down onto the frame unless the leak only gets significant when the engine warms up and is pressurized and thus the coolant could also be expelled sideways from the leak source. Try looking at the areas you have located before you add coolant, then watch immediately afterward to see if new fluid has hit those locations or not. Jacking up the right front wheel to get a better look may also be of help. Let me know once you find it if it is an unusual sort of a leak.
I have the '04 Dodge Durango service manual if you need some specific information about the leak site.

QUESTION: It's the 4.7 V8 if that helps didn't check under it again but the reservoir is half empty.
AnswerHi Rich,
I do show the cooling hoses main connections to the 4.7L and see that there are a 'to' and 'from' pair of cabin heater hoses on the passenger side of the engine, closer to the front than the rear. So take a look at those and the lower radiator hose that returns to the engine nearby. Of course the overflow bottle could be leaking as well.
