Sounds like somebody installed an aftermarket fan switch. Look at the engine side of the radiator and see if you find a probe going into the core itself. If there is one there, follow the wire going to the probe and it will take you to a control box with 2 wires going to it and a small knob. If it's there, one wire will be going to the cooling fan and the other will be going to a power source. It may not be plugged into a power source. While it's running, do you see bubbles in the resevour? If you do, you may have a leaking head gasket causing it to overheat.

My daughters 05 Taurus the power windows stop work

The windows likely need new motors. A pain to install. Sounds like this car is coming to the end of life. The cars is likely worth 2500 if everything was working. Don't put $500 in power window repair, because then you will have fan repair and many other nickel and dime issues.

If she can ride-share with someone (you) for a few months as she save up a down payment and buys a newer Toyota or Honda or Nissan.

Good luck

I have a 2000 lincoln continental and have recently replaced the thermostat due to over heating. after purging the coolant system the car will still 0ver heat am I not bleading the system right or is...

Provided the thermostat was put in right there are several things to check. Your engine is also air-cooled. There is a series of switches which work off of engine water temperature and the A/C setting. The electric cooling fan may have 2 speeds. If the electric fan motor or if the Relays or activation sensor do not work, the engine will not be cooled by air. The water cooling system is not good enough to do the job by itself.

The electric cooling system is fused and has a Relay.

Have someone look inside the radiator, if possible to try and see if the water is circulating. Remember the normal precautions about antifreeze spraying under pressure. If the radiator is clogged, it may need to be serviced.

Replace thermostat

follow upper radiator hose to aluminum housing this is where the thermostat is. be sure engine is cool remove radiator cap or reservoir cap if no cap on radiator disconnect upper hose from thermostat housing. remove two bolts in housing and remove housing. replace thermostat and reassemble. when finished refill anti- freeze leave cap off and start vehicle with heat on high. run the vehicle like this until air stops bubbling out of coolant and heat is hot steadily. continue topping off coolant during this process and be sure cooling fans engage before completion. then youre all done

Ive got a 323ci bmw on a 2000 plate with 23000 overheatin

repl temp sensor. run 12v to motor, does it run? could be resistors, they're hidden all over the car, thanks to the ******* engineers that put this piece of **** together. or the fan blades could be blocked.

radiator clogged, did someone put stop-leak in it? Remove thermostat drill two 3/16" holes in it 180degress apart, install 12 degree cooler thermostat.

check to see if fan clutch is working properly.

Electric fans do not work do you have any ideas my car runs very hot fans never seem to come on

Electric radiator fans? Just a guess but it could be the water thermostat. They are very inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. This is the function of the thermostat which is inline to the water pump and allows the engine to warm up before cooling through the radiator then when the fan thermostat on the radiator heats up the electric fans will run. You might be able to squeeze the upper radiator hose to feel if pressure is building up or water is flowing.

Xk8 Jaguar cooling fans do not come on at all. I have checked thermostat for engine. I have taken fans out and they work with a battery hookup. I can't sem to find a fan relay. Fan fuse is good. Car...

I had the same problem on my XK8 and I figured out that due to the age, this could be a failure of the thermostat. The thermostat is a valve that is closed when engine is cool and opened when it is warm. Quite often for being old is does not operate properly and the coling liquid is being blocked in one part of the circuit. The temperatuire sensor starts the high fan mode that keeps on all time.
A way to check on that is to see the behaviour of the cooling fans. If the high cooling mode of fan only appear after a few miles nd keep on going from this point it is very lickely a problem a thermostat that has to be replaced. Just have to purchase one in any internet reseller and get your mechanical shop to replace it.

98 runner cooling issues

You probably have airlock in the cooling system.

Not sure about the 4 runner's cooling system, but if there is airlock I usually take the coolant back out, take the thermostat back out, fill the engine block from this hole with 50/50 coolant, reinstall the thermostat, upper hose, fill the radiator and tank, then run the vehicle with the heater on max (rad cap off) and then fill the rad as the rest of the air comes out.
