SOURCE: cooling fan not working

The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.

SOURCE: 2005 Pontiac Montana SV6 heater blows cold when slowing to idle

How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

SOURCE: Radiator Fan's Run All The Time

There are 2 things that will cause this to happen. 1. The thermostat needs to be replaced and, 2. The coolant sensor can be bad. When I had this problem, I changed them both at the same time, she been just fine since then. Also, I had the check engine light on, and got the code from AutoZone (it's free!)

2007 chrysler pt cruiser cooling fan does not work with ac


If refrigerant is low , high side pressure may not be high enough to engage the pressure switch to kick on the fans. Have the a/c system evac'd and recharged to capacity then recheck fan operation. Also, extreme cold weather can reduce high side pressure on a fully charged system preventing fans from coming on.

Engine overheating on low rpm


Could not agree with you more - was thinking that it was a circulation problem with coolant when you mentioned your suspicions.

Engine cooling fan will continually run,


It seems you are low in coolant. The temperature sensor has air to sense instead of liquid and temperature gauge will be low. Try to fill up with coolant but sometimes it's hard to get rid of air from the system. Have you changed the engine thermostat?
Hope it helps

2007 Pontiac G6 GT radiator fan keeps running after engine is turned off. Runs for another 4-5 mins after engine is turned off.


Heat sensor keeps blowing air thru radiator until it cools, then cuts off. Some auto do this. If it bothers you let the engine idle a few min. after you drive it and then turn car off. When you drive your car and the engine is hot it heats up even more when you turn it off because the water has quit circulating. The fan will run til it cools. It's supposed to do that.

93 villager runs good, but temp. gauge runs up to the hot line, but never runs hot. is the a colling fan that should go on.


the cooling fan should come on low speed and then high speed as it gets hotter.

The fan should come on anytime the a/c clutch engages, even cold engine.

Running hot


Sounds like Clutch in your fan

The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.

Hope this helps!
