I've replaced the thermostat. Have been bleeding
the cooling system. Been keeping the coolant full.
Have a good flow going no leaks anywhere. But
still over heating and no heat in the cab. Head
gaskets r fine. Whatever can I do?
How hot does it get in degrees F? Any signs of over-heating other than the temp gage? Does your coolant reservoir boil over or anything? Maybe you need to check temp sending unit/sensor? Are the heater hoses hot with warmed up engine? Do you have circulation through heater core? The temp door under dash may have a problem? Any applicable trouble codes?
