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".

Those are usually for the lower hose so it does not collapse under high RPM
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.
