Mike are we talking abut the auxiliary fan or the main cooling fan? The temperature sensor is located on the lower part of the radiator header tank. Regards John

You should check the thermostat. There must be a sensor connector on the thermostat housing. If you bypass that connector and the fan runs, then the thermostat is damaged and needs to be replaced. If you follow the radiator hose you will reach the thermostat housing.

Overheating: cooling fan won't ingauge

I would first check the fan relays make sure they are good ..If no problem there then i would disconnect the wires going to the cooling fan..turn on your a/c ..that should activate the fan even if the vehicles cold ..see if you have voltage across the wires plug the meter right into the wire you should have 12 volts..if you do then its the fan..if the fan comes on during a/c but dont come when vehicle gets hot,then its probably the temperature senser that tells the fan to come on..Its located near the thermostat.

Coolant senser

218 is about the right temp for the fan to come on. How hot does it get? Does it cool down when the fan comes on?

1. Auto Zone should help you with the thermostat & its location, they have acess to repair print outs for do-it-yourself repairs.
2. front wheel vibration, try rotating the tire front to rear & see if the problem moved to the rear. it did you'll know you have a problem with a tire or wheel.
if it doesn't change you;ll need to have a local mechainc that has front suspension expirence to inspect.

Mercedes sl300 fan switch

There are several applications that this water pump is designed for. I know that primarily there are 2 switches used and they install in the t-stat housing portion of the water pump assembly. I believe that there is a single pole senser for the gauge and either a 2 or 3 pole senser for the aux fan and poss.compresser shutoff. I hope this is an o.e.m. water pump because the after market ones don't last as long and have higher failure rate. If it is an after market I would be suprised if the switch fit. If the switch came with new pump install original switch into new unit with new crushwasher. I'm assuming that you are talking about the aux. fan because the fan clutches are all hydraulic with the exeption of the 102 engine wich is a four cyl. Also there are some plugs that need to be transfered and they are all plugging up bores for coolant temp. sensers. If this fan switch won't go into the original pkace try another senser hole and plug up the other one. it doesn't matter wich port the senser goes into as long as the thred is the same. There sometimes a small hose that atatches to the back of the pump if not the pump comes with a plug. Like I said ther is several different applications. I'm an M.B. tech- if you have any more questions just post them and I will look at them

1999 olds intrique where the fan senser?

The temperature sensor is what usually tells the fan to power on, it should be located near the thermostat in the cooling line, it would be a good idea to check the fuses first and the fan relay.
