The only thing I can think of...do you have the right fan belt?
Could be that your idle speed is too high, or engine is running too hot causing the PMC to deliver a richer mixture,
Coolant Level too low (or sensor went bad) or Engine Compartment Temp too high / engine compartment fan failure
Most cars will receive adequate air flow for cooling purposes when driving at usual speeds. A clutch fan saves gasoline by disengaging when engine revolutions per minute excede a certain value. If the engine is consistantly running hot, the problem probably lies in the ignition system. The vacum advance may be stuck, or the timing advanced too far. Your carb might be out of adjustment, and the engine running too lean. If the enginge is still runing hot after 15 minutes on the freeway, it is not the fan.
It could, the computer will disengage the ac compressor if the engine temp is too high.
If your air conditioner is on, the fan(s) will most often run steady. If the AC is off (or you have none), it could be that you engine is running too hot for various reasons. What does the temp guage say? As well, it could be a faulty fan relay switch.. or faulty fan switch sensor in the radiator.. or a faulty temp sensor on the engine. Lots of possibilities.
Because its too old LOL
they cost of running the programs is too high
Is the whole unit running or just the fan? My thermostat has the option to run the fan only at all times and also runs the fan when the temperature gets too high (or low) in the house.
The engine computer (PCM) operates the fans by opening and closing the ground for the fans. The PCM will command the low speed fan to come on when coolant temp exceeds 221 degrees.The fan should always come on whenever you turn on the A/C no matter the engine temperature.The fan will also operate with the engine off when the engine coolant temp is over 140 degrees.The PCM will ground all 3 engine coolant fan relays when the coolant temp is 235 degrees or the A/C pressure is too high and run the fans on high speed.
The electric fans are controlled by a computer. The fan speed is set by engine temp, A/C being on and ambient air temperature. High fan speed is needed if the A/C is on or the engine is hot. If you're concerned get the cooling system checked out, you may have a clogged radiator core.
Your Lumina 2001 engine light might come on while the radiator fan is working because the fan is turning too slowly, is damaged, or is not cooling the engine correctly.
The enigine is running too hot...
