I know this is a 4x4 Chevy group, but a motor is a motor and I thought someone here might shed some light on my problem. I drive a school bus. It is a 2004 on an International Harvester frame. When it is above 32 degrees the heat gauge reads 190. When it is 5, like here today in Wisconsin it wanders between 165-170. All heaters are going full blast and the passenger area never warms up. Removed the thermostat, tested it, tested a new one and put the new one in. Same thing. It's almost like the radiator is too big for this engine in cold weather. Any suggestions on what else to look for and any solutions. Lots of kids will thank you.
