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!

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..

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.

2008 Trailblazer, installation went very smoothly (took me about four hours in total for the fan, new alternator, and replacement serpentine belt)! I can already feel a change in performance, I’ll have to wait to see if there’s a change in fuel economy.
A couple tips:
– I ordered the 2008+ P-030017 version, but it came with the manual for the P-030016. This really wasn’t a big deal, it was fairly straightforward what needed to connected where. The kit won’t include a coolant temperature sensor, so you don’t need to drill any holes or make any permanent modifications.
– As others have mentioned, a power cable kit and HO alternator. I swapped up to a 300 amp alternator (needed a slightly smaller 91 inch belt, down from the stock 91.5) and added an extra 0 gauge cable from the battery to the alternator, seems to work well. That being said, I can see the voltage jump and dip a bit as I accelerate. Not a big deal and I haven’t had any other noticeable effects, electrical-wise.
– The fan clutch removal tool was really helpful, but the prongs on the tool that connects to the engine side are a bit weak. They deformed a little bit because I failed to push the prongs all the way in to the pulley, but it was easy enough to bend them back to shape. There’s a point on the car at about 4:30-5:00 (in relation to the pulley) where you can slip the engine-side tool under the frame so you don’t have to hold both tools at once, that way you can press against the frame to loosen the fan clutch.
– The most challenging part was routing the wire for the ECU. The digital manual for connecting it to the E67 ECU in my Trailblazer doesn’t specify what pin is needed, but it’s the rightmost connector of the three and the fourth pin closest to the large pin (also known as pin G49, which is set aside for the radiator fan relay). I’ve attached an image of the necessary pin you’ll need to use.
– The fan is LOUD. As other comments have mentioned, people will be able to hear you coming. It does appear to have a lower duty cycle mode that is enabled when under accessory power – when you turn the car off, it’ll run for an extra 15-20 seconds at this slightly lower speed. Otherwise, it goes from off to full speed when the coolant hits temperature OR you turn on the air conditioning. I may look into a manual method for adjusting DC power to force the fan to run a bit slower, but we’ll see.
All things considered, I’m very happy with it. Highly recommended!
