Ok I'm know I'm not going to be able to make this meet.
Truck is having some overheating issues that are puzzling me.
Today being in the 90ish range, the truck was running good and all sudden temp gauge shot up. And I shut her down before anything could happen. Lucky I was waiting for wife so it sat 20 mins or so.
I let it cool, jumped on highway to throw cooler air into it, and spent 45 minutes or more in Walmart ( hate that place ).
We started home and got to a light and temp started going up so I dropped to neutral and held tack at 1600 rpm and it stayed cool.
This happen weather A/C was on or off.
Thinking it might be low on water, but checked reservoir tank and has coolant. Going to let cool and check the radiator itself and see how coolant looks there.
