Five choices in order of probability >

  1. cooling fan not kicking in due to a bad thermo switch (on radiator, wire leads to fan)
  2. The thermostat could be bad
  3. A pressure leak at the radiator cap would cause an overheat problem. Is the coolant 50-50 antifreeze and water?
  4. A bad water pump
  5. A restriction in a coolant line or radiator

    A “very helpful” rating for this answer? Thanks!

2008 HHR at 30 MPH the temp meter reads in red area, 45 mph reads normal?

Check the electric radiator fan, if vehicle heats up at low speed then it sounds like the fan is not working! at high speed the air going through the radiator cools the engine. Check the fan out! God-Bless! Hope this helps you. or check to see if you have a bad fuse for the fan or relay is bad and will not turn on fan.

I had a similar problem on one of my bikes. Turned out a "Test Port" had rattled loose between the carb and the intake. I threaded a screw in the hole to prevent the leak and problem was resolved.

you need to check throttle body and carbeurator. clean carbs. check your oil and check that your battery is holding a charge. has the bike been sitting for awihle? gas might be bad so replace it.

Dometic 2008 fleetwood discovery...............Freezer side works ref. side does not. Will only run on propane not shore power

Make sure the cooling fan on the back is working properly it should be running if the unit is on. While your there check to make sure the plug is still plugged in for the ac to work. Also check the breaker in the box reset if necesary. All this good on the ac the heating element would be my next choice.
