My radiator fan stays on its not the relay,could it be the sensor? where is it located if it is the sensor? thanks laurie

Could very well be the sensor (thermostat). No idea where yours is located, but parts store location chart may help, or you could buy a shop manual.

Need to find location of coolant fan relay and sensor for 1990 pontiac sunbird ?

if your rad coolant fan is not working check the fan itself as this is a common problem on these cars. disconnect the plug from the fan motor and run jumper wires directly from battery to the fan motor terminals. if the fan doesn`t run replace fan motor. if it does run the check fuses then fan relay. the relay is in the relay box, the coolant sensor for the fan motor is in the head that goes into a coolant passage that has a 2 wire connector.

Location of coolant sensor 2000 ford tarus station wagon 3.0 liter v-6

Not sure I follow you.
The engine temp sensor sends a signal to the engine computer and the computer decides when to activate the fan relays. So if you have power to the fans you would also have power to the high or low speed relay the temp sensor is probably working. There is a third relay for the ground circuit.

Fan will not come on by itsself. Where is the coolant sensor located?

coolant temp sensor is usually located on the radiator. also check fan fuse, fan relay (in fuse box and relay box), and intake air temp sensor (thats usually on the intake tubing before throttle after Mass air flow sensor)(can be check with diag scan tool specific for that vehicle). if the fan is on a belt, check the fan belt and check for rotted or broken wires going to the fan motor.

When the car gets hot, the fan dont kick on. i need to know where the coolant sensor is. and how to fix it

Start by checking the fuse panel under the hood to see if there is a cooling fan fuse and relay...after checking these components and determining that they are good...make sure the fan motor is good by hot wiring it to the battery...if the fan is ok then the sensor may be at is usually located on the housing where the thermostat is located or where the top radiator hose connects to...there may be two sensors being for the temp gage and the other for the could disconnect the sensors one by one...start the car to see when the gage dies then you'll know which one is for the fan

Radiator fan not turning on time

Check the rad fan fuse or the relay under the hood.
Is the temp going too high? Check and make sure you are not low on rad fluid (engine cool). An air pocket where the fan temp sensor on the rad is located will not activate the sensor.

Failing that, check the rad temp sensor which activates the fan. If this sensor does not close at high temp...the fan won't work.

i believe you have a sensor problem best way is to replace the sensor but you can bypass it it will automatically make the fan come on when you bypass the sensor

95 grand am radiator fan only runs with AC on

Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson

Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.
