Do you have a "check engine" light on? A bad temp sensor would give a wrong reading. Do you get heat from your heater core? Also make sure you are getting a good flow from catalytic converter and muffler so you know they aren't plugged heating up engine temp. Also make sure all your heat shields are in tact. Are you using 50/50 mix or mostly water? Though in cold temps you normally want to use more antifreeze less water, I would try more water, less antifrezze.

MY VAN IS OVERHEATING WHAT ARE THE STEPS FOR TROUBLESHOOTING


When does it overheat? At idle, or at highway speed? Is the coolant level where it should be? Overheating at idle or highway speed may be a faulty thermostat. If it overheats only at idle then it is likely a cooling fan fault. To determine if the fan is working start the engine and switch the A/C on, the fan should come on, if it does not, then you need to have the computer "scanned" to see if it can detect the reason for the fan not coming on. If the fan is switching on, then you need to have the water pump checked to see if in fact it is pumping coolant (this could also be the cause of overheating at highway speed) If you are overheating only at highway speed you may want to have the enigine checked for a blown head-gasket, or faulty radiator.

1996 Jetta appears to overheat but no coolent loss


the temp sensor is the trigger for the fans!!
the thermostat may be in upside down??
check new thermostat in a pot of water & heat it up watch that it opens up when it heats up should be at aroun 96 degrees F
otherwise the radiator may need a good clean out or a recore!
there my be a blocked water gallery so engine may need a flush aswell

2002 jeep cherokee overheating AGAIN


You say you changed the fan relay and the thermostat? when was the last time you had the cooling system flushed? you could have a blockage in your cooling system that could be keeping the coolant from circulating..

Engine overheating at high rpms


check the casting on your replacement water pump..4.0l engines require a reverse rotating water pump..may be causing your problem.

2002 jeep liberty has very little or no heat also overheats in warm weather changed water pump and thermostat also had system flushed


sounds like a head gasket problem. A minor leak there will pump compression into coolant and force it out of heater core. Any unusual steaming from tail pipe? Also: if radiator was flushed "in car" sometimes debris does not come out. Try flushing with it out of the vehicle. Jeep radiators are notoriously small for their application if not at at least 90% they will not work correctly.I'd look at the hg first though otherwise, your symptoms seem to be contradictory.

2002 Dodge Ram 1500 with a 3.9 engine overheating


Check your rad hoses. They will tend to collapse (**** in) & cut down on flow at highway speeds, more than city, due to increased demand & flow on cooling system. If they don't feel relatively stiff, I'd change them. You might even see them **** in while sitting and revving the engine a bit.
