When our coaches were built there were not many options as far as cooling our engines, The first part of this month July 7th, 8th, and 9th I made a trial run through the Mohave from the Central Valley of California to Maricopa Arizona. On the 8th leaving Maricopa it was 115 seemed hotter where I was at a storage unit with nothing but black asphalt and metal buildings. Yes I have faith in the work I've done on the 1978 Birchaven all new belts hoses fuel lines, aluminum water pump and pressure tested radiator. The coach ran great, but when the thermostatic fan kicks in it sounds like a 747 on takeoff and noticeably slows the coach, Id estimate with consistent throttle pressure 3-4mph. The only other issues were in the 100 degree plus weather was fuel boiling out of the carb and starving for fuel until enough air was blowing thru the engine compartment. Anyway who has installed electric cooling fans I think the desert guys running 700hp engines in the Baja 1000 have radiators mounted in the back of the trucks with the fans blowing up, around 5500 cfm fans if I recall. Surely this is more than enough to handle a 225 hp car engine in a motorhome. I've also heard of GMC people running 7lb radiator caps? Why sacrifice 24-1/2 degrees over a 14lb cap and have your engine boil sooner? I will deal with the fuel boiling out of the carb separately. As I belie it is part exhaust Cross over and the heat from the front of the engine on the metal fuel line.
