the truck is overheating only on the freeway. i just took out the old t-stat and it says its a 88°c and the new is 82°c.

Sounds good. Your MPG might drop a touch, but that's it.

You might want to replace your fan clutch if it's overheating on the freeways. Not positive but , your old one was a 195*, and the new one is 180*F. If that doesn't solve your problem then it might be the fan clutch or a radiator going bad.

yea i already replaced the clutch fan. it did help a lil.

Perhaps a radiator flush might loosen up some debris. The worst situation is water pump failure.

Cheap fix ... radiator flush ... Jiffy lube or oil can henry's is about $100
Expensive fix water pump ... $300 and up for parts and labor

Sounds like radiator to me. Its not plugged with mud or stuff that prevents air flow through it??

If the water pump was toast, you would have coolant leaking from the weep hole. Not a lot, but enough to notice.
