When do the radiator fans come on in a 1995 Chevy Monte Carlo z34?
The fans are controlled by a temperature switch, which normally turns the fans on when the engine temp reaches about 212 to 220 degrees.
What temp should cooling fan come on 98 Chevy venture 3.4?
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.
What temp does the cooling fans come on for a 1996 cadillac northstar 4.6 engine?

Why would the cooling fans not come on in a 2000 Buick LeSabre?
I verified that the 2 coolant fans come on at low speed once coolant temp reaches 223/225 degrees I thought this was too high a temp so I checked with local Buick dealer. They claim 220-230 is still considered normal operating range. If you want to get cooling fans to come on earlier and at hi-speed just turn on A/C or defroster. With A/C on temp never seems to get above 205. If the engine isn't coming up to teperature, they will not engage. If they are not getting power due to a relay or wiring. If the computer is getting false information about the engine temperature (temp sensor?), they will not come on.
The radiator fan does not come on when the engine temp goes above 210 degrees The cooling temp sensor cooling temp switch and one fan relay has been replaced. The fans do activate when the ac is on.?
== == Cooling fans are designed to start at 235 degrees
What makes a 92 stanza run hot until you turn on the ac?
You probably have a bad temperature sensor. TS reads the temp of the coolant and turns the fans on when hot enough. Without it the fans arent controlled by temp. When you turn on the AC the fans always come on.
What are the symptoms of a bad engine coolant temp sensor?
If you unplug sensor and one or both fans come on.
Your radiator fan come on and stays on when ever the engine is running can this be correctd so that it only comes on when thermostate tell it too?
your themostat does not control your fans your fans are controled by coolant temp sensor if they are running all the time the problem is in the coolant temp it not working and ecm is overriding it and alowing the fans to run all the time.
Your 1995 Ford Escort overheats only after using AC for few minutes otherwise temp is fine What could be the problem?
you need to check cooling fans with ac on
Your 97 camaro comes close to overheating when sitting in idle car is full of coolantfans seem to be working and after sitting in idle low coolant light comes on and temp gauge drops while car moves?
well i have a 94 z28 and it will run up to about 210 when idleing because the factory set the fans to come on around there not shure of the exact numbers the fans come on when not that hot but i think its on a low speed setting so it don't realy do much but when driving the car produces a huge air dam that forces air through the radiator and the fans don't even come on. i noticed when i was doing some work on my car and i unpluged the air intake temp sensor after a while the fans kicked on to high prob as a safteyand would not go above 190. so ill double check that if you want try it to make shure if both fans work on high speed i cant explain the low coolent light though exactly what temp does it get to does the temp hold stedy but hot is it a V8 or V6
