RE: 00 Dakota 4.7 runs hot
I have this problem, but only AFTER I tried to flush my radiator fluid. Interesting that when I drain from the drain plug/petcock on the lower part of radiator, the coolant reservoir doesn't go down whatsoever....this is my post on another forum:
After about 50k miles, I decided to give it a go to flush my radiator fluid. Figured I would use a radiator flush (I bought a Prestone radiator flush). Anyhow, removed the petcock on the lower driver's side of the radiator, drained fluid, noticed that coolant in reservoir tank didn't go down much. Undid the bleed bolt and loosened radiator cap, topped off the reservoir with 50/50 mix. Went for a drive, turned on heater full blast. Temp gauge went to max after about 10 min., checked coolant level in reservoir tank, it was full. thought maybe I got air into the system, so undid bleed bolt and let some air out, but coolant level still full. visually checked all hoses to make sure no kinks, and didn't see any. Any thoughts or ideas? some radiator fluid seems to be coming out from the radiator cap, could this be bad part? Any hellp appreciated, I'm a noob at this stuff
Anyone have this problem? I'd hate to change the radiator...
