    The Thermostat is probably not working properly. It could have and leak in a head casket. Does it lose a lot of water? I think it should be the Thermostat though. Just have it replaced and see if it solves thew problem. If you know how you could replace it your self. It will be on the engine input from the Radiator,

SOURCE: 1989 Ford F250 Diesel is spiking to red in temp gauge

When a temp gauge spikes it usually is not a real heating problem, but possibly a sending unit, or wiring to sender problem. Most especially with the diesel and its vibration. Difficult to say from way over here, but I would rather believe that there may be a bare spot on the wire which occasionaly touches ground.

SOURCE: electric cooling fan on ford five hundred not

Check the fuse for the fan and you could test to see if you have a voltage running to the fan when the car starts to overheat. If you have no power to the fan then trace the wore and see if you cant find the problem. If you have power then the fan motor is most likely bad.

SOURCE: 2000 Ford Taurus Antifreeze boiling over

hi, the problem you are having is down to one of a couple of problems, now as you state the air blows cold then this points towards the thermostat not opening so this then dont pump the coolant round the engine resulting in the top half of the being hot and the bottom half cold so this is why you only get cold air.

so the first thing you should do is get the thermostat changed.

you also need to bare in mind that the problem could be a damaged water pump this does happen from time to time so check for any signs of water leak where the water pump is by the timing belt, if their is no signs of leak then the thermostat is the likely cause.

you also need to think that as the engine has over heated this could have caused the head gasket to fail so this will need looking at to if after changing the thermostat you have the same over heating problem.

so replace the thermostat as this has clearly gone and then when you re-fill the coolant make sure any bleed screws are undone if you have any on your coolant system usually located in one of the top hoses running around the engine, (not all coolant systems have one as many are self bleeding so dont worry if you dont see any bleed screws) now when you start filling the coolant up make sure you only trickle the coolant in to prevent any air lock building up in the system.

if you are unsure what you are doing then please leave this to someone who has some idea of the kind of work involved in this type of repair

I have a 1999 Ford Focus Ghia. Neither the Air con fan nor the engine cooling fan are working. I've checked the fuses, and it's not those.

The engine temp will go up when it is loaded like a hill climb. Also the fan only is run when needed for the engine, it is computer controlled, so unless the engine is overheating at idle you are likely just not aware of how it is operated by the computer, the engine temp will be about 230F before the engine fan is turned on.. As far as the AC blower fan goes you need to pull the fan and see if it works when 12 volts is applied with a jumper. You can run an active system test with a factory scanner and it will test the fan operation.

What will cause temp gauge on 92 ford tempo not to work. No codes for coolant temp sensor. Only codes, 159,157- bad MAF, 522 - Neutral safety switch.

temp gauges will not work if there is insufficient coolant in the radiator, the sender unit is faulty or the wire to the sender is broken or loose
the coolant sensor unit is a different item and reports engine coolant temperature to the ECM for air / fuel mixture adjustment
It will show up as a possible cause when the air/fuel mixture is out of parameters the same as HO2S sensor , Maf/Vaf and other causes

My 01 Pontiac Montana is trying to overheat at high power

If your vehicle doesn't actually overheat, just getting hot, I think that's the normal behaviour for these cars. My 03 AWD behaves the same way. When driving uphill, especialy when towing, the temperature rises close to the red marking, but I have never experienced it overheating. I think that the temperature has to rise much over the normal driving temperature to activate the two electric fans.

1998 cavalier overcooling and loss of power driving

ever change your fuel filter??? them cars are real bad for bleeding air from engine if you say changed the rad, had serious leak and topped it up again.. over cool sounds like you had a previous overheat and the thermostat is now stuck open....thet effects mpg because the long warm up time tricks the temp sensor into thinking its cold . temp sensor is todays choke on fuel injected cars. it tells computor to dump extra it can act like its "flooded" some temp guages work both the computor and the dash gage, some cars have two , one dash one computor, new costs around twenty bucks and filter should be around ten

Sounds like a faulty temp guage/r a strange malfuntion in a sensor to me as well, only doing it when it going up hill really makes no sense for the way the cooling system works so I doubt that its actually running hot, which is likely why he asked about the gurgling noise, it would force water back into the resivoir if it was running hot assuming that the thermostatic radiator cap is working properly.

It sounds normal, but perhaps the radiator is a little small. Make sure the core is clean by blowing it out with compressed air (from the engine side) to clear out bugs and other debris. Make sure the overflow/reserve tank is at the proper level. Check the coolant level in the radiator when engine cold--it should be right at the top of the filler. These are all preventive, not a cure for anything.
