The fan is only one part of the cooling syste.

The cooling of the engines works like this, Oil reduces the friction and keeps the engine from rubbing metal on metal.

Water circulates through the engine block by means of the water pump.
The water stays in the engine block by means of a thermostat. The thermostat is composed of treated metal that expand or contracts at the designed temperature.
When that temperature is reached, the thermostat opens and allows the water to escape the engine block to go to the radiator. Standard RAM air usually cools the water just fine, and the water pump recycles the water back thru the engine. If the incoming air in the front of the car (the grill) is not enough to cool the water, the FAN comes on. This forces air thru the fins of the radiator exchanging the heat.
Another important thing is clogging. If there are any clogs that impede the flow of coolant in the block or the radiator, this will also cause overheating.
A failure of any part in this symphony can cause your engine to overheat.

The next easiest step to correct, is to make sure you have enough coolant. check your sensor Then check the thermostat. Then check the waterpump.

good luck and don't forget to vote!!!

My 2000 stratus fans run non stop so I have no heat. New rad, new termostate. What else could it be.

Even if the radiator fans run all the time, you would still have heat in the car. The thermostat prevents the engine coolant from flowing thru the radiator until it opens.
Could have low coolant and air pockets in the system.

2004 sunfire cooling is always on when the car is running

The cooling fan is controlled by a temperature switch located on the radiator or on the engine. When the temperature of the coolant exceeds the switch temperature rating, the switch closes and energises a relay that switched a voltage to run the fan and it will continue to run until the coolant temperature drops back below the opening point of the switch. In your case, you may need to have the cooling fan replaced.

Coolant is not flowing into expansion tank via little hose and car is overheating. As it is getting hot the coolant bubbles and spits coolant through the little hose but it is sputtery like it is tryi

coolant will not flow from the return pipe continuously.when the engine heats the coolant expands returns to tank. coolant fan starts engine cools down return pipe flow stops . fan stops after times, again coolant heats up and flows through the pipe. this cycle continues and go on.

Is there a fuse or relay for the heater in my 2002 ford expedition

No hot air is due to low coolant, or even poor coolant flow. The engine heats up the coolant, and it passed through your heater core, and the heater blower motor pushes air through the heater core to warm up the air. If your "fan"is working, but the air is cold, make sure your coolant level is good.

Did you check the coolant level? if your low on coolant the sensor for the fans won't work, also could be a bad fan motor or just a fuse, if you continue to over heat the car you can do a lot of damage to the engine, blown head gasket, and the VW's are expensive to repair, take it to a good shop and have them check it out.

Engine heat keeps going up even after refilling coolant.

are you leaking coolant ? or you were just low and added fluid to it ? if your car is full of coolant and still overheating change the thermostat first its the cheapest and easiest starting point.

If that does not work i would replaced the coolant temp sensor pretty cheap to that tells the ecu when to turn of your electric fan assuming you have a electric fan.

if you have a clutch fan aka belt driven you may need to replace the fan clutch its basiclly a unit that expands and contrancts a spring to turn fan off and on.

if none of the above work you probably have a faulty water pump even though its not leaking the propeller blade inside is likely rusted and limited functionallity

if this helps you please give me a good rating

Why dot't the radiatop fans in 1998 nissan altima work?

There are two possibilities first there is a coolant temperature switch that activates the fan relay that could be bad, second the fan relay may be faulty. It is doubtful that the fan itself is bad. I would use a voltmeter on the OHM setting which looks like an upside down U to check for continuity after the motor heats up check and see if the coolant switch is ok by touching the two probes to the terminals on the switch the voltmeter should read zero after the motor heats up if not replace the coolant temperatur switch for the fan if the switch is good replace the relay for the fan.

I dont have heat and engine over heats.While running coolant gets pushed into my resevior tank and almost over fills it. When I turn it off Radiator steams and coolant goes back into radiator still have no...

It's not the water pump. pumps can leak and shaft bearings go bad, but even then it is pretty much impossible that the pump won't pump. I'd start by changing thermostat. When re-filling, add coolant slowly and just when it reaches operating temp, shut it off for about two minutes. re-start, turn heater on high and continue filling till electric fan comes on (if you have one) at that point turn off again as before. Re start and run with cap off for about 15min. If overheat continues, remove radiator and flush, and bring to a shop to determine if there are any hydrocarbons in the cooling system. If so, there is a problem with either head gasket or head. (likely you will have fixed it before you get this far.)

Radiator Fan continuously running with engine off, discharging battery

It is not the fault: for long time Renault has that concept, that is to prevent engine oveheating when coolant circulation is suddenly stopped.

Radiator fan can continue to work up to 10 minutes after engine is off. You should worry about it only if it wouldn't stop even after 10 minutes.
