Bus running cold?

the heater only works if im absolutely powering around, and at that point the temp is around 150. usually it runs at 130 ir so, and the heater doesn’t work at all.

not really the worst issue i guess but it would be nice to get the heater going its a little chilly these days.

More than likely the thermostat is stuck open and allowing the coolant to flow too fast to heat up. Some engines have two thermostats, so be sure to replace both if that is the case.

that sounds about right. any idea what these engines are supposed to run at? its a 5.9 i think

I haven't seen any specific numbers, but diesels are generally supposed to run a little warmer than their gas counterparts to facilitate proper combustion, so I'd say 195-205? 210, maybe?
