    temperature normally runs 1 div below 1/2 but when idling temp slowlly increases well above 1/2 almost to the red when fans kick in and temp starts back down, is this normal, replaced thermostat and antifreeze, but still does it, doesn't seem to be losing antifreeze. I read many stories about Dexcool, is this the start of more serious problems?

Hello george.
It sounds like it may be the temp switch that turns on the fans if it don't heat up when your driving down the road and the temp stays at a normal temputure it sounds like the temp. sensor there may two on that car one for the gauge and one for the fans, But first you should check out your fans and make sure that they still work, You can check them either with a Ohms meter or you can if you don't have one of those you can try to unplug the fan and use a ground wire and a positve 12 volt power to see if the fans still work or fan depending on if you have one or two. there should be two on that car but what ever, You will find that if you do those tests you will find your problem, Which I think is the Temp sensor that turns on the fans itself. Let me know if that helps you out or if you need somemore help. I am in MI. so I can't fix it unless your in the U.P. LOL Take Care Hope It Helps You Out...

My guess is that your electric fan is NOT operating at all. Under normal conditions, just going down the highway, your cooling system will function just fine without a fan running. The air flow through the radiator is adequate to keep things cool. However, when you stop, you quickly get into an "overheat" situation. Actually, you should be able to hear your fan begin operating when your engine temperature starts climbing or your air conditioner requires the fan to do its thing. Note: If you've ever severely overheated your engine, your problems may be worse than just a fan not running, but you really do need to confirm whether your fan is operating correctly, or not. Another note: I had a vehicle with a tendency to overheat when stopped. It turned out to be a faulty (leaking) pressure cap on the cooling system.

Hi there, ya that sounds like your fan stopped working. There is a few different things you can check. The fuse for the fans The relay that controls the fans, and the fans themselves. You really should get that checked out, eventually your engine will start to overheat which can lead to major damage. If you dont feel up to do the job yourself any compitant auto shop can check it out for you. Hope that is helpfull.

Need to know where the fan motor and resistor is located on the 2003 Ford Focus. Car overheats while idling, driving, in park, and it'll still overheat when the heater is on. Tell me what site I can find...


Cars usually overheat when the thermostat is faulty, coolant level is low, or the water pump fails. If your cooling fan on the radiator does not kick on shortly after the engine reaches operating temperature, you may have a bad cooling fan, cooling fan relay, or cooling fan fuse. If your engine is overheating, start by checking the fluid level, and installing a new thermostat.

A blower motor resistor is the device that controls a car's cabin heating and air conditioning unit's fan speeds. This usually won't cause the engine to overheat, your A/C fan may not function or only function at one speed. Here is a Blower Motor Resistor from Autozone: http://www.autozone.com/autozone/parts/2003-Ford-Focus/A-C-Heater-Blower-Motor-Resistor/_/N-jk8uvZ91tag

Within five minutes, it starts to redline overheat, if you drive 2000rpm, it goes down, but goes back up when you idle


it could be a stuck thermostat, or a plugged radiator or cooling system, check to be sure cooling fans come on when they should or it will overheat. when moving it is air cooled through radiator. thats why it over heats at a stand still. check fans first, it could be a fuse relay or the coolant tempurature if fans do not work or coolant sensor not turning on coolant fans at the proper tempurature.

The engine cooling fans in our 2003 Buick LeSabre LTD don't shut off when speeds over 25 MPH are reached.


There is nothing to worry about. The cooling fans do not operate by engine speed, but rather engine temp. If the fans stopped working, then there would be a problem with either the cooling fan relays or the temp sensor which operates the fans. Otherwise, you are fine.

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful

How does the fan operates, does it starts and stop. Car shuts down, red light come near milage guage, have to let car cool down and start again. Can fan cause this problem? Pontiac Gran Am 1998.


the cooling fan should come on about 105-107C and shut off about 95-97C
does the car overheat just sitting running not moving
but if the car overheats on the highway then it's not the fan
check the fan operation run the car till the gauge is over half and watch the fan
if the fan woks then check coolant level if that's ok then try a thermostat
hope
