Volvo d13 engine fan control solenoid location and way to put a manual switch

This here Video shows the location of the engine fan control solenoid on a Volvo d13 engine. The fan is controlled by air coming through the small green air hose from the solenoid located under the steering shaft. The solenoid is electrically controlled by the engine computer aka ECU. When the ECU suplies power to the solenoid, the solenoid opens and send air to the fan clutch. When air is supplied to the fan clutch, it turns off the fan. By default, the fan is on and will stay on if no air is supplied to it.

Brother thank you so much for this video you just save my motor I'm fully loaded and my fan was not working wen the truck is moving, is working at low speed or wend the truck is not moving. With this trick I'm going to make home and have the solenoid replace

Tank you!!!!

Thanks bro!!! You save me)

[@GeorgiGeorgiev-ne9ps]

There is an easier way. Pin 19 on Ecu under the fuse box in dash. Its that wire and you only need a switch to ground

[@drevilatwork]

That is correct, i can confirm that cause the truck i have now has an viscous fan clutch and that one is controlled by the ecu so there is no air going to it. I did wire a switch to that pin and it works...

My truck it’s a Volvo d13 and the engine fan it’s not working the truck it’s getting hot and turn it off, what that mean???

[@user-yx5tt8rt2e]

What happens if the air line is leaking ? Fan directs ? And stays engaged all the time ?

[@moneymikeslickwill8749]

My fan clutch was bad

[@Straight101]

So did you replace the solenoid or what

[@sunwaterflowz]

I just changed fan clutch fan never comes on unless i unplug solenoid will changing solenoid make fan come on and turn off as normal???

[@drevilatwork]

I dont think so

[@ahimnieves127]

On my D13 the wire coming out the fan clutch broke, I’m stuck on road, I’m I going to have to replace the fan clutch?

[@drevilatwork]

Is the wire that broke electric or is it a small air hose? Either way, system is designed to have the fan always on if anything beakes. If your fan dosen't turn at all with the wire broken that means the fan clutch is bad

[@gjames57]

What year is your truck? My fan turns with my engine. On my other truck it is like yours here barely if at all spins until it kicks in. A shop told me I need a clutch. I may but he said it is NOT locking in to me it seems locked in all the time.

[@moneymikeslickwill8749]

If u can prevent the fan from spinning while the engine is running the clutch is bad even a little movement while engraved is sign of a bad clutch

[@moneymikeslickwill8749]

What if I can’t stop the fan with it disconnected? My clutch is bad huh?

[@sunwaterflowz]

What amp on off switch do i use??, what gauge wire???

[@drevilatwork]

About an amp so any gauge wire will do. I did put a switch on mine and it works great. Only things to remember are: start the truck with the fan off AND if the truck computer turns the fan on like when u climb up a hill and u let the temp get up yo the point where the truck computer turns the fan on, wait until the computer turns the fan off again, before u manually turn it on again, else the fan will stay on until u stop the truck and turn it back on. This is because, when the computer turns the fan off, it dose it by supplying ground to the switch. The switch always gets positive . It's the ground connection that the computer controls the switch with. So when the computer supplies ground to the switch it also checks for continuity. When you have manually turn the fan on from the cab you brake the connection and the computer thinks it's a fault and stops supplying ground until u stop the truck
