[Spridgets] High engine temp NON Spridget

[Leo]

Will do a pressure check in the morning as I have a radiator system pressure
check tool and I am going to install a mechanical guage to see the actual
temp and then will get back to the list.  Thanks for the suggeations guys as
I really need this truck going now not later.

Leo...

Check the radiator cap.  Is it sealing properly?  Could there be a pin hole
leak somewhere in the hoses or radiator?  These are pressurized systems. If
the pressure is too low (leak somewhere), they will overheat. Especially
under load.

Cheers!!
