My 03 f250 powerstroke runs perfect temp all the time till i tow something like a camper or my boat it then overheats clear up to hot and a red check guages lite come on. It just started last summer towing my boat i use a edge program on lowest setting but it has been on for 3 years, so i just changed the fan clutch and it did not help, coolant is full never loses any and clean as well. I still do not get the roar everyone else says they get from the fan clutch even with the new one. any help would be great.

Thanks

Does it run at the normal reading when you're not towing? does it feel like it really is that hot or could it just be the sensor?

Always normal not towing, and yes it is getting hot.

If you're moving at a pretty good speed, the fan doesn't have to work that hard to cool it. If it gets hot gradually, it could be a flow problem. Radiator restriction, (bugs in the fins or inside plugging), water pump fins worn down. A radiator shop can check the flow with a tester in the radiator hose. Some have other means.

When it's hot, check the rotation with the engine off. Does it freewheel or is there more drag than when it's cold?

It is loser hot than when its cold.

That's not right. The heat should tighten it up.

It's very critical how the clutch is stored in the box and how you receive it. If the clutch
is facing down in the box you don't want it. It had better be facing up.
