I have a 2004 ranger edge 4.0L V6.
I keep having a an overheating issue only when going up hill.
I tried checking the fan clutch, doesn't even get passed one rotation so I think thats good.
I don't think it is the water pump as that went out on me about 2-3 years ago and was replaced.
Should I do a coolant flush? What are some other test i can do to determine the cause of the problem?
Also it was bubbling/overflowing from the reservoir today (first time that has happened)
