New Holland TM viscous fan

[YELROM]

The viscous fan seems to be engaged all the time on our TM155
Is there any sensors i can check or will it be the viscous fan its self
We have another TM we could swap sensors with

Our TM140 is engaged all the time. Was told by mechanic that the idea is crap and it's better to retro fit the old style. He told me to carry on - fuel usage is higher tho ?

Be warned. Our was stuck on. Eventually it self destructed. New radiator,rad cowling, fan, viscous unit and hoses later.

The wires had rubbed through on the inside of the conduit from the main harness down to the viscous unit on mine. Take the top rad hose off and slacken the radiator mounting bolts to lean it forward - saves the skin on your knuckles when fiddling with the connector.

Put on an old type non electric viscous fan, far better and cheaper

Is it not electric engaged then, mine is?

Does the error code still come up if you change for the old type ? cheers

 

[ridger]

Never noticed any codes, have 2 changed now, justbone more tractor to change now sometime when it sticks on

I will have a look and see if any wires have rubbed through

Have noticed since the fan is continually engaged our is using a fair bit more fuel

I assumed there would be some sensors

 

[ridger]

I can't remember the exact figures but I think that the ordinary viscous coupling was 200 euro cheaper than electro viscous, and only had to plug out the wires.

Yes big increases in diesel consumption wen fan is engaged full time.95% chance your problem is the short loom from front of engine down to the fan hub.and yes a fan hub from from the older type will work too...

 

[Lincsman]

I assumed there would be some sensors

There will be, electric is an electric clutch, viscous is a gunge in the hub that locks up when hot, out of interest what does the gauge say, but guessing it will be a different sensor to switch it on, possibly its always locked up unless it gets power from a switch... have a look in the fuse /relay list in the book.
