Heather, the radiater fan relay is solid state, mounted behind the facia
on a bracket drivers side, right of left headlamp assembly, feed by fuse 24, 40 amp in the pdc, box, I'm assuming thats what your talking about, the coolant sensor signals the PCM ,when temp hits 212*F, tells the solid state relay to turn the fans on, check the ground for the fans, should be near the relay. if by chance you have no air lock in the cooling system, after the pump was replaced. Belt routing ok, was this done by experinced help. GOOD LUCK, RDJRP

I have a 1999 cadillac deville. My cooling fan is not turning on. My car is over heating. Is there a connection?


There is nothing really in the water-related part of the system that has anything to do with the fan. The hoses, thermostat, heater core, etc. are simply a conduit to move the water through the engine to provide cooling. The fan is the crucial element to avoiding overheating. While the car is in motion, air flows through the radiator, cooling the coolant down and removing the excess heat. Once you stop, however, or get in a stop-and-go environment, there is limited airflow through the radiator to provide this heat reduction. That is where the fan comes into play. What makes the fan work depends upon what you are asking the vehicle to do. Testing the fan circuitry is rather simple if you understand a few things. The fan only needs to run to cool the engine if the engine coolant gets above a certain temperature (usually about 220F). The fan will be ordered on and run until the coolant drops to about 180-190 (thermostat temp). The confusion is that the thermostat has something to do with turning the fan on. The thermostat only controls the flow of water through the system. It stays closed until the water temp reaches it setpoint (usually 180-190F), then open to allow water to flow through the engine. There is a coolant temperature sensor, usually installed near the point where the thermostat is, and it sends coolant temperature information to the ECM. The ECM uses this information to control fuel-air mixture and to control the cooling fan to operate when needed. The fan and the fan relay can be tested very easily by simply turning on the car's A/C. Even if your A/C unit isn't working, simply putting the dash controls to an A/C position, will automatically power up the cooling fans, since the A/C requires CONSTANT airflow thru the font of the engine to maintain cooling. If the fans don't work in the A/C position, then the problem is not likely to be the coolant temperature sensor. It is more likely to be a fan relay or the fan itself.

My car heats up in stop n go traffic. The temperature gauge can go as high as to the 'RED'. I adding water and coolant everyday. Are the fans supposed to come on as I am driving and the car heats up?


if you are adding coolant every day then you are experiencing coolant loss
could be from a leaking pump gasket , head gasket or other leaking item
have a compression test done to check for head gasket , cracked head
next have the cooling system pressure tested to find the cooling leak
lastly check the fan, fan relay , fuses and coolant temp sensor unit for correct operation

I have a 1999 oldsmobile intrigue with a 3.5 engine and it is overheating what might be the problem?


It's usually the thermostat, I woud pressure test the cap. It may need to be flushed. Are the fans working? Is there a 50/50 mix of anti-freeze

The electric fan is does not seem to be engaging at low speed causing the engine to overheat when the A/C is on... the engine fan starts and stop irregularly when waiting for the engine to cool down... is...


Hi!!

There should be a fuse/relay box in the engine compartment close to the battery, If your vehicle is equiped with two fans, there should be two relays. There has to be a cooling fan(if equiped with two) that comes in as soon as you turn the A/C on, is your vehicle has one fan, it has two speeds, when the A/C is turned on, the Hi speed kicks in. Sensors in this circuit that are relevant to this function are, Coolant Temp. Sensor, Engine Temp. Sensor.

Check fuses/relays for the cooling fan(s), if OK, check sensors.

Good Luck!! Don't forget to rate this post!!!

98 Camero overheats when driving slow or stop, ok


You need to get the cooling fan checked,it may need a temperature sensor,fan relay or the fan motor may be burnt out.You can check the fan by running your own power and ground to the plug that comes out of the fan motor,unplug it and put the ground to the black wire and positive power to the other one,if it works then the next step would be to check the fan relay.The most common problem if the fan doesn't work but can be made to work with jumper wires is the temperature sensor,you can check it by unplugging it and jumping the wires in the plug.If the rad fans work then you are down to either the water pump or a plugged radiator,a rad shop should be able to narrow it down for you.
