Description

Introducing our new plug and play fan kit for the six cylinder trailblazers! This kit includes a custom made fan shroud and utilizes a powerful single SPAL fan unit. In the 02-07 models, the fan is controlled by a thermostatic switch that you will tap into your water housing outlet (tap and drill bit included!) The 08+ models are controlled by the PCM (to which you will add another computer pin to). Also includes wiring harness that plugs into fan, two splices into fuse box (wire tap splices included) and gets power and ground near the battery. Average install time 1.5 hours. Requires fan patch (free! just cover return shipping) to delete fan codes from PCM (02-07) or to operate fans (08+). Our efans have been credited with gains from 12-18rwhp and usually pick up a MPG also! PLEASE NOTE: Due to the high performance of the SPAL fan, it will be louder than your factory fan. It is a single speed on/off fan.

Now available for rental or purchase – PCM of NC Fan Clutch Wrenches! Simply add to your cart at checkout and save yourself a trip to the auto parts store. Don’t want to keep it? Send it back within 30 days in working condition for a full refund!

  1. James

    PROS:
    Great product. Great Instructions. Great value. Would strongly recommend to anyone with an I6 TB. Noticeable increase in milage and power.

    CONS:
    Would highly recommend a power cable kit, and even possibly a HO alternator. (My 05 TB has the occasional headlight flicker, this has made it much worse. For the first day, seems like the engine would stall at traffic lights, but that went away after the first day)

    Order the water neck oring before you start your install. This was a dealer only part in Florida, hard to find on a Saturday. Had to buy the entire assembly for $52.

    I Agree with James I highly recommend a HO alternator due to the current draw (DBelectrical 250) the fan was a really good investment at a good price..

  3. Wayne D.

    It has been two months with my Spal Efan kit and it works great. One added benefit not listed is the AC works great even at idle. I did notice a bump of in MPG over my failing Clutch Fan.
