2002 7.3 Coolant Temp runs hot with load

[WD40]

You didn't do wrong by putting that 6.0 cooler on your truck. You do have 3.73 gears and running 35 in tires, but that shouldn't be a big deal unless your toyhauler is real heavy. If your truck don't have a real heat gage I would put one on and try that before I did anything. It for sure will be worth installing a coolant filter.

Thanks again for every ones help. I have a few things to do to the truck. Thanks to all and in 2 weeks I'm on my way to Cal to go camping up the big hill. I'll let all know how the truck did if you don't here back it's because the heads blew off the truck and I'm camping on the side of the road LOL

Hope you have a great camping trip and not beside the road somewhere. Let us know how it goes.

Just got home. On the way the truck was getting warm again. I pulled over, and checked everything out. Found out the truck wasn't holding pressure. Replaced the cap with OEM. All is good. Thanks again to all.
