overheating hauler
 

im having a overheating issue with my truck
its 2000 ford f 250 deisl
it can ideal fine with no problem
for as long as i want i can drive for as long as i want
but i can go over 70 or pull my trailer if i go over 70 75 then
it starts to run hot i slow down to 50 it cools down doesnt make sence

Could be the clutch fan, at higher RPM's it may not be keeping up.

I'd check out the radiator first. Sounds like it isn't cooling effectively. Maybe too many bugs in the cooling fins. JMO

X2... does sound like a restricted airflow issue.

i change the water pump an thermstat today
no change if i let it idile for a while its still fine an the hose
are some what soft soon has it get close to the red
they get hard where you cant squeeze them an you here boiling

Overheating
 

Have you tried backflushing the radiator?

no i havent im going to take it tomorow to radiator shop
but i dont think its going to help why would it do it at 80 not idile
or any other speed

Overheating
 

It may be partially blocked, and the result is like running a radiator that is too small for the engine. It can't keep up with that heat the engine generates.

no here you i hope its not a head gasket i will
set that bitch on fire there no way im doing head gaskets
it not smoking
its not eating antifreeze
no water in the oil
no miss

More than likely it's the radiator. Like the others have mentioned it can be partially clogged and have the same effect as a radiator that's too small. Head gasket is unlikely. The 7.3 that was used in 2000 had almost no problems with head gaskets and if that was the problem it wouldn't cool back down by dropping your speed. If you have a temp. gun you can try checking the temp. of the radiator after it has been warmed up then shut down. If the lower part of the radiator is a lot cooler then the upper part it's a good indication that the radiator is clogged.

yep you guys are right it was the radiator took to a shop an they said it was fuck thanks for the help
