I'm glad for all the information I've gleaned from you guys over the years, sorry I apparently can't use the search function properly. I've got a 94 factory turbo 7.3 it's been a great truck it's awesome and I love it.
For some background I bought it while I was in a bind about 4 years ago and love it, it makes about 25 miles grossing 26k every 6 weeks with a 32 foot flatbed and John Deere 7230 with a loader to load chicken litter, it's always got warm on the pull but always went right back to cool with some trans braking and a light foot when needed, I've got glow s#it gauges and keep my EGTs under 1200 as much as I can, it's spiked to 1300 ish but nothing sustained.
I turned the pump up 2 or 3 trips ago, maxed it out and drove it easy until I bought a Duramax (insert hate here)
Fast forward a few weeks and I jumped in it to go help a buddy cause the LML was tied up, 8 miles down the road got to and helped the guy and headed back and see my heat gauge between L and maxed out. Got home parked it and put a gallon of coolant in it the next day.
So the truck stays cool around the house runs like it always has until I put it on the road, it takes 3 or 4 miles at 70 mph and the heat gauge gets way up there but it doesn't lose coolant, I can hear the fan but it doesn't sound very aggressive and nothing has changed other than the temp gauge. I can idle it around the house all day and it stays cool.Truck got a new water pump two summers ago but not thermostats or anything else. AC works great unless I'm idling in the heat then 1200 rpms keeps it cool. I'm thinking a clogged up cooling stack.
It's a 94 7.3 factory turbo rclb 4x4 ZF5 with a luk flywheel and maxed out pump with 190k on it
Tldr; truck ran great until I parked it now it's running hot
