and a few other gurus.
The other morning I had a warm shower. Should have been piping hot but wasn't. As it usually happens we were heading in the truck to Salt Lake City that morning for a couple days. I called Rudy and he gave me a few things to check but since we were leaving I didn't have time.
Just got back and first thing checked the coolant level. It was low, could just feel it when I stuck my index finger in the tank, and the overflow tank was almost empty. Called Rudy in a panic thinking I had a busted tank. Rudy assured me that is a fairly common problem and to fill the tank with coolant or distilled water and turn it on. Tomorrow I'll replace the radiator cap and hose and clamps.
This is the kind of help that makes this forum so valuable!
