TimberJack Posted April 18, 2022 Share Posted April 18, 2022 Picked up a new fan clutch for my 2008 CHU and the wires coming out of it looks nothing like the old one. Called my dear an they said the old part number is no good and it has a new number. I asked them was there a new bracket for the wires since there wasn’t the long plastic stem coming up off the new style. They said no, what’s supposed to hold it from spinning the wires around? Has anyone installed one yet? Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/ Share on other sites More sharing options...
Joey Mack Posted April 18, 2022 Share Posted April 18, 2022 did you get sold an ASET fan clutch instead of an MP fan clutch.. Yes there is supposed to be a bracket to secure the wires.. Have you looked it up on the web yourself? I have been doing that more and more myself... jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-495577 Share on other sites More sharing options...
TimberJack Posted April 18, 2022 Author Share Posted April 18, 2022 Yeah I check, I looked an the plug is round for the mp8. I looked up part number an it shows it’s for mp8.

Joey Mack Posted April 18, 2022 Share Posted April 18, 2022 is there an updated jumper harness that you need? I have been out of the dealership for almost 3 years so I am rusty on this, just tossing out some basic questions... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-495580 Share on other sites More sharing options...
TimberJack Posted April 18, 2022 Author Share Posted April 18, 2022 No it plugs right up. The top one is the new one they gave me, the bottom is what was on it. That bottom one has a long hard plastic stem that goes up to a bracket to keep it from moving side to side. Well the new one doesn’t have it so there nothing to keep it from spinning around.

Joey Mack Posted April 18, 2022 Share Posted April 18, 2022 well sir I may not be clear on the issue here, but, you need a bracket, even if you make one.. the wires cannot be just hanging there and they need to be secured and not flapping in the wind created by that huge fan.. with respect, jojo 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-495582 Share on other sites More sharing options...
Mackpro Posted April 19, 2022 Share Posted April 19, 2022 Being that the truck is a 2008 it would have come with the extremely large Borg Warner Cool Logic fan clutch. They were very prone to failure. They finally came out with a much smaller fan clutch by Berh that requires a new fan blade and all hardware and this all came in a kit from Mack . There were about 6-8 different kits for different engines and truck models. This also requires a software download from the dealership to make it work correctly. They used the same harness plug connector but one fan clutch used more pins than the other . I also have the parts list and instructions for each kit and diagrams showing how to mount the bracket that holds the wires on the fan clutch. P m me if anyone need them 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-495616 Share on other sites More sharing options...
Mackpro Posted April 19, 2022 Share Posted April 19, 2022 Also , I believe the Berh fan clutch has been replaced with a different brand clutch that looks very similar and uses the same fan blade and no download was needed. We just replaced a Berh fan clutch in one of our 2016 CXU’s . It came in a Mack box but it was not made by Berh.

fjh Posted April 19, 2022 Share Posted April 19, 2022 IF IT DOES FIT? you still need to tie off that proboscis that the wires come out of or you will have a major screw up in short order! there is a bracket that comes with the conversion kit i believe you may have to make something! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-495633 Share on other sites More sharing options...
JMAR Posted May 17, 2022 Share Posted May 17, 2022 Did you figure out anything on this? I am replacing my clutch and have the same issue. Dealer claims they sold me all the right parts, but the new clutch is obviously different Quote Link to comment https://www.bigmacktrucks.com/topic/69558-fan-clutch/#findComment-497839 Share on other sites More sharing options...
