Have you changed the thermostat lately? I did and mine still ran very warm, but didn't over heat completely. After looking at several sensors and relays I changed the thermostat again (Honda part this time) and it fixed it. I was told by the Honda parts guy that the after market parts do not let enough coolant flow to allow the fan sensor to work properly. So you have a resticted thermostat flow along with no fan (until the ignition is OFF) both helping the car run much too warm. Hope this helps.
The fan might spin slowly, or not at all. By not spinning at speed, the fan will not cool the radiator enough and the engine could overheat.
On my van, we tested the wires going to the radiator fan. After disconnecting the battery, we applied power to just the wires. If they spin, they work.
No, the radiator fan is electric.No, the radiator fan is electric.
No, it cant. Check your thermostat to see if it is functioning properly. Next and the most important check is to do a fan clutch test. 1. Shut of engine 2. Spin the radiator fan blade. 3. If your fan clutch is working ( dampened) it should only turn 1/2 to maybe 1 revolution. If it continues to spin, then the fan clutch is shot and you are not pulling in any air to cool the radiator. If this is the case, replace the fan ( clutch comes with the fan). This answer does not pertain to electric fans
How to remover 1996 ford mustang radiator fan from the radiator motor
Dead fan motor, bad connetion to fan motor, faulty swith on radiator. To check, pull connetion to fan apart, this is a two spade connection found close to fan. Run a live wire from battery to connection and another wire from connection to negative pole on battery. If fan starts to spin, the motor is fine. This test can also be done at the thermostat switch on the radiator. Fault must be at radiator switch. This switch is located half way down the right hand side of the radiator. Drain radiator, remove switch, replace switch, refill radiator, bleed cooling system. Problem solved.
Remove the wiring harness from the back of your 1999 Cadillac Escalade radiator fan motor. Remove the radiator fan motor retaining bolts. The radiator fan will come off.
I check radiator fan, and relays and they are good, what can be a problem when my car reaches temperature to open termostat radiator fan does not work
Yes. Cooling fan, engine fan, and radiator fan relays are all the same thing.
The radiator coolant fan fuse can be found in the fuse box. The radiator fan fuse will be in the second column, fourth from the top.
When the engine is cold, open the hood before starting up. Try and spin the fan by hand. The fan should spin with considerable resistance. If the fan free wheels with no resistance then the fan clutch is bad. If the fan does not spin at all, the clutch is seized.
If it has a properly fitted fan shroud, it doesn't matter how close the fan blades are to the radiator. If there is no fan shroud the fan blades will have to be within a couple of inches of the radiator.
For the radiator electric fan... Depends which fan you're talking about ? The heater fan or the radiator fan ?
The radiator shroud.
The radiator fan may be smoking on your Mustang if there is a radiator leak. You will need to check the radiator to make sure there is enough water and fluid inside.
Generally, the blades of a fan spin in a counter-clockwise rotation (when facing the fan), so that the air is pushed downward if its a ceiling fan, or toward you if its a standing fan.
Some spin clockwise and some spin counterclockwise. If the fan is driven with a v-belt it spins clockwise. If the fan is driven with the flat side of a serpentine belt it spins counterclockwise.
If the smoke is coming from the electric fan itself, then it needs replacing. It could be the smoke is steam that the fan is drawing from the radiator, and you have a coolant leak at the radiator.
If it is a clutch fan, it will only spin when the engine gets hot. You should be able to spin it with your hand but not freely like a household fan. If it is an electric fan, it won't come on until the engine is HOT. Or sometimes with the A/C. You can check with a test light to see if you have electricity to and through the thermal switch on the radiator. (When Hot) You can also supply 12V manually to the fan to see if it is good. I blew a fan, in the process the fuse blew too. Check the fuse box in the engine..
The radiator fan is intermittent. It works if I mess with the radiator fan connector
The 1997 Oldsmobile Cutlass radiator fan switch can be found in the fuse box. The radiator fan switch will be in the third column, second from the bottom.
The heater fan in inside the HVAC housing behind the glove box. The radiator fan is mounted to the radiator.
Check the fuse and the wiring.
Low coolant, radiator restriction (inside and/or outside the radiator), inoperative radiator fan, missing/broken fan shroud,
