2002 Dodge Ram 1500 Overheating
They replaced Fan Clutch, Water Pump, and Thermostat. It is still overheating. What more could it be? They said they checked the temp going through the radiator and it was fine. Anyone else know what could be causing the problem?
Thanks!

Didn't some of the rams have water pumps that the vanes need to be in the opposite direction? I know it sounds crazy but make sure of the pump rotation.
And the truck is overheating cause you can see it is, or the gauge is telling ya? Like the man above said. "Coolant Temp Sensor"?
I'd hate to think you havd all that work done for a bad sensor.
Just my 2 cents.
Good luck.

It's definately getting hot. You can hear it bubbling after it gets hot. I'm not sure about the water pump going in the opposite direction. I'm thinking now it may be the lower hose collapsing or air pockets in the line. I don't know what else it could be.

Bad radiator cap. If you hear bubbling, then air has entered the system. That happens thru a rad cap with a broken, or weak spring.
Water boils at 212 degrees at sea level because of atmospheric pressure. The reason the cap is sprung so hard is to create "more atmospheric pressure". The more pressure, the higher the boiling point of the water in the coolant system. If that cap is not working properly, then it's like having a tea kettle on the boil.........LOL.
Check the cap, and if that's the problem, replace the temp sensor anyway. It has taken a beating. They are not very expensive.
One other thing, and this is not an educated guess because I am more into diesels. If your thermostat was recently replaced, and it mounts sideways......I am quite sure that there is a vent hole that needs to be in the 12 o'clock position. I may be wrong.
Check that cap. You couldn't possibly have done any more repairs.LOL.
And I forgot.......make sure your coolant reservoir is at the proper level too. And that there are no restricions from the radiator into the container.
Good luck.

I had the same problem with my 2002 ram and changed all the same things. It had everyone stumped. I looked for answers on every website possible. Finally found a lady's response where she had changed the radiator overflow tank. When my son ordered a new one from the dodge dealer, it was called a degasser tank? My son changed it and I've had great heat ever since. Just a suggestion for you. (I did smell antifreeze before changing it)
