    The new clutch fan will bring your temps down they have a problem with the blade restricting the air flow..............if you begin to run hot you should notice this when moving between sites. We have found if we angle the blade slightly left or right the temps fall back down. The crews have not reported any problems when actually plowing .........only when moving between sites.

    you must have a 6.0 4L80E because my duramax/allison trans gauge barley moves plowing or transport!

    The B&M gauge I'm putting in considers up to 250- normal. And they measure after its been through the coolers (where the install sheet recommended putting the sending unit).

    You may want to check out the "Chevy Truck Discussion" forum- this subject has been covered extensively! If you click on the "2500hd's overheating" thread you will discover there are more of us having this same overheating problem than you care to know about! Good Luck and please let us know if you have any luck with your dealer fixing the problem.

    Do the search on overheating...GM was not putting the proper fan clutch in the plow prep package... They have a bulletin on it, only most dealers don't want to search for it. The correct clutch will solve your problem...Chuck

    any suggestions on how to get my dealer to find the bulletin?
    I can't seem to get them to do anything since "they have never heard of such a problem". I have tried on the other forum to get someone to post the TSB number but have had no luck. Any help would be appreciated!
