Re: Radiator overheating already
Why do you have a spring in the upper rad hose?
Those are usually for the lower hose so it does not collapse under high RPM

Re: Radiator overheating already
Bi-pass the temp controller and see if the fan goes any faster. Does the fan power go thru the switch (sounds like it does). Might want to switch to a simple on-off and relay.

Re: Radiator overheating already
Ok, temp gauge is hooked up and working. Its hard to test an overheating condition at night with the cool air. I refilled the radiator and overflow per Speedbumpauto's recommendation. Just driving around the neighborhood in first gear i could only get the temps up to 190. Just to test the controller I dialed the pot to the max (should be hottest) setting with the truck idling in the driveway and the temperature crept north of 225 before the fan kicked in. At least now I have a reference for what is "hot".

Re: Radiator overheating already
I was just suggesting a check to make sure the fan was operating at full speed when it is supposed to, Thought was maybe all the controls and wiring were not allowing full power to the fan.

Re: Radiator overheating already
It was the best fitting hose I could find locally. I have removed the spring.
OrrieG, If I bypass the controller it will run at 100% power all the time (or when switched on) which would defeat the purpose of the unit itself. It is designed to ramp the fan speed to temperature. Hopefully now with the temperature gauge working I can get this dialed in. Thanks.[/QUOTE] I prefer the 180* thermostat and I have the electric fan se t to come on at 195* Except when the A/C is on then it is switched with the A/C.. Cycles on and off and stays around 185* +/-5*
