Cooling issue I just purchased this old car for my daughter. someone put an external thermostat inline. The cooling fan does not come on!!! They put the external thermostat where the fan cooling sensor goes. where can I find the wiring for this? You can only drive it 4 miles before it overheats. Thanks for your help

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

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

Cooling fan won't come on when car is up to temp. Fan came on when power wire to it was grounded out. The new thermostat is hooked in but does not work either. Wondering is the coolant temp sensor is bad...

Sounds like you should take it to a qualified repair shop to have this sorted out. new thermostat is hooked in but does not work either. ??????? The thermostat does not open ???? Engine over heats ? You put it in backwards . Cooling fan relay turns on the cooling fan . It's tough to guide someone through a diagnostic procedure when then don't have any idea how the system works .

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.

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.
