The powertrain control module (PCM) also controls the cooling fan.

SOURCE: 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.

SOURCE: 1996 saturn sl2 fan coming on late an over heating

Start with engine cool, & remove radiator cap. Check level in rad & fill to an inch or so from top of rad. Start car & turn heater on.(not defrost)
Now let it run until engine gets up to normal operating temperature & let it run until rad fan comes on & off, 2 or 3 times. Rev engine slightly every so often just to help disperse air in system faster. Fill rad as needed during this time. After you do that, and fan has come on & off 2 or 3 times, put rad cap back on & fill return bottle to proper mark, then see how it is.
I suspect it's just air in system & this should cure that . If not get back to me.

SOURCE: Does a 95 cutlass supreme have a fuse for the

There are three fuses and two relays for your coolant fan. They should all be in your underhood fuse box. They may not be marked "coolant fan", so check them all, (2) 60 amp , (1) 20 amp, (1) 15 amp. If all the fuses are good, you may have a bad fan switch (temp sensor). It tells the fan when to turn on, follow the wire from the fan motor to find it.

SOURCE: Does a 95 cutlass supreme have a fuse for the

Yes, in the underhood electrical center, a 60 amp with a red wire going to relay 1 and a 20 amp with an orange wire going to relay 1 and a 15 amp with a brown wire going to relay 2 and another 60 amp with a red wire going to relay 2. The diagram doesn't show a temp sensor, but it does show dark blue and dark green wires going to the power train control module, so it must get the temp input from there. The second fan usually comes on when the A/C is turned on and it apparently gets that signal from there also. Hope this helps.

What Switch or control makes the radiater fan come on? and need the diagram for the radiator control switch, 1993 saturn sl2.


Ok. The way your system is set up,you have a fan switch located in the engine block,usually near the top.That fan swtich sends the voltage to the fan motor or to a fan relay then to the motor.You can jump the fan motor directly to make sure the motor itself is not burned out by unplugging the motor and running a jumper wire from your battery pos terminal to the terminals on the fan motor itself..If you have checked the motor and it does work,then the easiest thing to do is simply replace the fan switch.You should have a Coolant temp switch and a radiator fan switch and possibly and Radiator fan relay.I would try the radiator switch first,then replace the relay.The coolant temp sensor is for the computer and usually doesnt tie into the radiator fan switch.try that and repost.Good luck

92 saturn sl2 1.9 liter engine have problem with cooling fans not coming on. Relaced relay in fuse box , jumped wire to fan motor, fan motors works. took wire off cooling sensor and jumped . fan still...


I had this same problem and put a switch inside the car to turn on the relay remotely. But I believe it is the connection at the temperature sensor near the top of the transmission. My wires were stretched at this sensor from the factory. I have not tried to replace it rework it but if you used an ohm meter you could determine if the wires and or sensor have continuity. This is not the same sensor that runs the temperature gauge in the dash.

Radiator fan will not run but motor is good


follow the wires coming off the fan they will lead you to the relay from that the relay will run to the temp sensor which trips the relay for the fan
