Have a radiator shop check for blocked cores
have a compression test done
water pump not an issue unless you have removed the ac compressor out of the system and now the water pump is being driven in reverse because an idle pulley was not used in place of the compressor

check the ground wire from the battery to engine, make sure it is tight at all connections.

SOURCE: electric fans do not run

Che if you installed the right thermo sensor, check for broken wires and if the car has the wrong coolant sensor or the wrong thermo sensor it will not work right.

SOURCE: 94 acura tries to overheat after reaching operating temp replaced radiator relays for cooling fans and thermo switch, new hoses and thermostat, after reaching operating temp top and bottom hoses swell

Based on what you are saying and what you have done so far you have a cylinder head gasket leaking combustion gases into the cooling system, this type of leak causes a gas bubble to form around the thermostat and then it will not work properly. Also when this type of leak is the problem there will be no white smoke out the tailpipe or coolant in the oil, the gasket only leaks on the compression stroke.

Front and rear blow little to no heat


If you know for sure the thermostat is working, it could be low on coolant and has air pockets in the system. Only one radiator hose should be warm until the engine reaches normal temp, and both heater hoses should be very warm.

Overheating 2003 dodge durango. What could be the problem??


When engine running, ensure no engine combustion gas bubbles in coolant resevoir (if so, the head gasket is blown).

Check cooling fans are operating ok (when required when car warms up), if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Replace thermostat.
When re-filling cooling system, bleed off any airlock as necessary.

Check for collapsing (soft) coolant hose on suction side of waterpump when engine revs above idle.

Intermitant temperature


Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
