Great info. My fan clutch will not turn on , even manually. Going to do these tests. Thank you!
If your truck has sat for sometime , build up the air pressure and shut it down with key on and manual override to fan on , 2 or 3 light taps on the fan clutch solved my problem within seconds ,don’t pressure wash around the fan , I e seen it several times se e times , it will cost u nothing to try this, !
Thank you, mine wouldn't turn on 1 time but then was fine. Now I know how to manually turn it on.
This helped me very much. Thank you :)
Muy buen vídeo mi pregunta es? Cuando el camión corre en mi aire acondicionado enfría; cuando el camión está estacionado prendido el aire acondicionado sale caliente? Qué será? Pensé que era el fan clutch pero no sé ni qué cambiarle según las pruebas que usted hace en este vídeo también abanico de embriague está bueno

Hello I got a 04 Freightliner Columbia 120 day cab with Mercedes engine mbe 4000 and check engine light came on and my clutch fan is not engaging on and I have a override switch and it’s not working when I switch it on. I need help any ideas? Please help me
If everything checks out okay with your fan clutch. Why won't my manual switch not turn the fan on? Could it be the switch itself?
There is a selonoid with a wire when you push the switch it sends power to the selonoid check air going to it and power
@@jorsot8839 I replaced the computer on my truck and now it works.
Is ok when your truck is but you fan is spinning in normal way? Without making an noice? Or it supposed to be off while running the engine? Pls clarify
I have an issue where my engine temp is only fluctuating between 190-200. My fan clutch is working. The thing that's happening is the fan clutch keeps operating sporadically no matter what the coolant temp is. Sometimes the fan will come on for hours and when it does my ac stops blowing cold. When the fan shuts off it blows cold again. Anyone have any idea? Seems like the thermostat is stuck open which is causing the temp sensor to be confused causing the erratic operation of the fan.
Solution? I’m also having eradicate fan activity. None of these videos are similar to my problem. Mine is best described as sometimes my fan works sometimes it doesn’t.
I have a dd15 , my fan woudent shut off, no air leaks , I started the truck and built up the air pressure and turned on the fan engage switch , gave it three light taps with a hammer , problem solved , just try it guys
Great info can you be friend by any chance? 😅
If I put a manually fan switch , will it mess up my sensor because now my a/c clutch keeps turning on and off , and at the sensor connect and disconnect and it turns on and off .
My fan clutch is good and I replaced the sensor and fan is still not working is there anything outs to check ?
if you disconnect the Air line that goes to fan clutch fan should stay on. if it dont stay on after disconnecting from sensor you fan clutch have problem. sometimes fan dont turn on on time when driving. we can add a switch inside truck to turn on and off the fan manually. any machanic can do it under 50$.
Desi thanks for you reply I’ll try this tomorrow
Update I disconnected the airline and fan was working fine what can I do to get it working the right way if not I guess I’ll add the switch
I have a rattling noise ( like keys jiggling together) what can be my issue
Men if you are a mechanic you are not a good one))))) you have Kysor style FAIL SAFE clutch. If its going to be bad it will be always ON and you will see air leak around. Check to see air leaks and check the hub bearing condition
you can bend pipe and zip tie air line۔ also its just to save road service in case of emergency۔ not permanent solution۔ also۔ im not a machanic۔
Hi. I had this problem. I climbed a mountain, then the fan didn't work at 230 Temperature, came red light and I stopped. After two hours I disconnected the fan wire electric and added antifreeze coolant. It worked, the fan working all the time and continued to drive. My question is Can I continue to drive more 2,000 miles to see my mechanic with the fan working all the time? I appreciate your answer.
Hi
@@luiscaceres3490 did you keep driving?
Some time it locks up because of water. All you need to do is tap it with a hammer lightly it will loosen the rust. Don't be that stupid to do it with the engine on. 😏
Thanks
Thanks
