SOURCE: Radiator Cooling fans pull or push air (93 Chevy Lumina 3.1 L) ?

A radiator fan is designed to pull air to pull air through the radiator to help cool it, while blowing the air on back across the engine to try to assist once again at keeping the unit running cool as to not over heat.

SOURCE: Are both radiator fans suppose to come on together?

I found this forum site and from what I can discern, both fans should be running once engine temperature sensor turns them on. Can you switch wiring from 1 fan to the other? This would let you know whether you have a faulty motor or relay. Maybe you can pick up some tips too.

SOURCE: 2000 chevy lumina. Is fan supposed to come on when car started

no fan comes on when engine cold start up .but it will come on when you turn on air conditioning or defrost on .if engine idling a while when temp get 190 degree the fan will kick on.if over heating you got air in system .wait until cools check coolant add more .crank engine let it idle few. minutes when start warming up turn off engine wait a while before removing radiator cap so you wont get scald.add more coolant .crank it again starting warming up turn off engine wait a while .add coolant .keep doing this procedure until your coolant stop dropping off .if you do this more than 6 times you got a leak some where.check crank level for signs.if oil level higher than normal.if everything looking good.when engine cool make sure add coolant to over flow jug cold level mark.

1997 Chevy Lumina 3.1 engine. The cooling fans aren't coming on tell the car heats up to over 250 degrees.


Did you check for applicable trouble codes? Anything? Some of the national brand auto stores will check codes for free.
Check the coolant temp sensor, if you haven't already? Some makes and models if you turn on the ac, the fan/s will run. If you unplug the coolant temp sensor, the fan may run.
I might want to use non--contact infrared temp gun just to double-check temp gage.
Have you ever checked thermostat or coolant flow through the radiator. I understand it only heats at idle.

Sir, my 1996 Chevy Lumina with a 3.1 engine, gets


there is a coolant temperature sensor in the system ( normally in the vicinity of the top radiator hose /thermostat. It activates a relay that switches on the fans--normally around 85 degrees c. Check both fuse and the relay for correct operation. The sensor unit will be squarish with 2 wires in the connector.

Hot light comes on 1998 chevy lumina


Has this happened suddenly? Or over a period of time?
Either way, it sounds from your description as if either the fan/s that assist in forcing air through the vehicle's radiator aren't operating; or, as likely, the radiator core is partially blocked with sludge left over from when the engine was manufactured. Might be worthwhile getting someone to do a cooling system pressure check.
Good luck!

97 chevy lumina are there coolant fan sensors


This year doen't use a separate sensor for the cooling fans, it uses the ECT (engine coolant temp sensor) sensor that monitors engine temperature for the fuel control system, the computer turns the fans (via a relay) on when the engine reaches about 225-230 Degrees F

Cannot get cooling fans to turn on for radiator???


The cooling fans won't run until either the engine coolant temperature reaches about 218 degrees or the air conditioner/defroster are on. Once the engine reaches appx 218 degrees the fan will come on and run until the coolant temperature drops a few degrees and will then turn back off. If either the a/c or defrost are turned on then the cooling fan will begin to run to remove the heat from the a/c system and should stay on until either is turned off. If the engine is overheating in slow or stop and go traffic then the fan may not be working at all due to a bad fan motor or blown fuse.

temperature sensor only controlls the fan going on and off but nothing to do with the running of the car like staling or not starting though.
