I have a 1994 olds cutlass surpreme with 3.1 v6. It is running hot. I have noticed the dual electric fans are not coming on until like 250 or 260 degrees one will come on then when the car is in the red temp wise, the other will kick on. When i drive the car the temp is just a little above regular temp. When i turn on the air, no fans. But i did notice a loud click sound going from normal air to max air and off. I have changed several things, temp sensor, thermostat, water pump, radiator cap, fan relay, nothing. I even unplugged the computer for a hour in hopes that it may reset, still the same thing. HELP! I am tired of chasing this thing.

Either the battery or the coolant is running low.

I had this same problem on a 91 camaro w/3.1 and I never figured out what caused it. The engine never ran hot enough to boil out the coolant. I resolved the problem by purchasing an auxillary cooling fan thermostat setup and wired it into the cooling fan circuit so the fan would come on at 190* If you are interested in doing that I might be able to help via e-mail.

It could be that your antifreeze level is low, there is a sensor switch to turn the fans on and it is on top of the engine block and it reaches into the cooling system to feel the temperature of the antifreeze, when system is low the sensor does not feel/touch the liquid anymore. Before starting in the morning, check the fluid in the radiator. It should be low , it's low from long term neglect or the system has a leak, If the system is full, it could be a bad switch, of lack of voltage to the switch caused by blown fuse or relay. it gets involved and needs a techniciann to check,hopefullyl it is just low antifreeze level.

You got me there...
It is very important that you bleed the cooling system with the heat on when you replace the water pump and/or the thermostat. Make sure there is enough coolant.
Good luck!

unplug the temp sensors and start your car and the fans should come on automatically. if they do you can drive it like that . wont hurt a thing the fans will just be on whenever your engine is running. if you shut your engine off they will shut off too .if they don't come on you may have to wire them into a relay that powers them when you start your car

The radiator itself might be clogged and needs cleaning out, it's probably not circulating the coolant efficiently enough to keep the engine cool

I hope it is just a fuse
