Hi
Yesterday I headed out to go get a horse, had my horse trailer in tow.
It's a pretty heavy horse trailer.
Pulling a hill and my radiator tank cracked.
I pulled over, removed the cap and let it idle while I put some water in it.
It didn't show that it got real hot. The wrench light didn't come on.
I turned around and coasted to bottom of the hill and filled it up with water, drove back to my house. No more hills.
Filled it up with water and let it run for a couple of minutes, it didn't get hot on the way back.
Changed out the radiator, filled it with coolant and tried the same hill. Began pulling the hill out of my place and it went into derate.
Wrench light came on. Pulled over, gauges were all fine.
Let it run for a little while while I checked fluid levels. Shut the key off, stetted it up and it ran ok until I was pulling the same hill that the radiator popped on and it went into derate again, same as before, wrench light came on, same scenario.
Turned around went home disconnected horse trailer. Went back and pulled the same hills with no problems.
Any suggestions or thoughts?
Sorry this is so long but I didn't want to leave anything out.
Thank you

wrench light should indicate a code is available
I imagine your oil cooler is clogged and your oil temps are soaring under load
Thank you Zmann. Going to do the EGR cooler and the oil cooler with bulletproof products .
Might as well.

IMO if you have the wrench light,, there should be a code as ZMANN suggested.

What code reader was used?

I don't know. Oriellys? Whatever they use. Going to take it to a shop tomorrow and have them check it out.
Thanks for the comment. All help is appreciated.
