SOURCE: engine overheat

Hi and welcome to FixYa,

Offhand it would appear that the radiator fan is not working. In some versions, either the A/C or the heater must be turned on for the radiator fan to work. In some other incidents, the fan utilizes a clutch. Common design makes use of the inverse property of silica oil to serve as the clutch. Still others have a relay that actually does the switching on of the fan. Of course it would be to your advantage to likewise check the temperature sensor on the radiator.

Good luck and Thank you for using FixYa. Happy Holidays.

SOURCE: '94 honda civic is overheating, temp gauge is

Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.

1998 BMW 528 recently replaced radiator, water pump & pulley temp gauge sat middle all good THEN 2 months after all this temp gauge goes past middle then dropped back to middle . Next day temp gauge...


It could be the thermostat but you need to check the fluid level and for any leaks (these could even be pin hole) first. If you have one of those infra-red temperature gauges you can check the temperature of the cooling system in the engine bay to double check. Generally the engine temperature should not go much about 90 deg C - this is when the electric cooling fans kick in - are these turning on?

The cooling system electric fans keep running for over 45 minutes. The engine temp gauge was in the normal range. There is no thermostat in the cooling system, the radiator was warm but not overheatin


there has to be thermostat sensor in the system. this is how the cooling fan is controlled.the water pump may be failing by not pumping enough coolant and causing the fan to run.longer that expected

I would do a sniff at the tail pipe to make sure you are not pumping coolant out the exhaust pipe.
sound more like a bad gasket than a bad water pump to me.

My temperature gage is going over in the red and my heat is not


Check the sensor which controls the cooling fans that cools the radiator it prevents the engine from over heating and allows the temp gauge to stay at normal range.recently had problems with my 2003 impala overheating it was the sensor had the thermostat replace as well.

Heater blowing cold air


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
