I5 Loose fan wobble clutch water pump question
I am seeing several fan clutches on Rock Auto - some say reverse rotation and some don't and I am confused. Are they all reverse rotation? Or do I need to specify? Thanks

I believe reverse rotation is referencing the direction of the fan spinning as it relates to the serpentine belt. A fan rotating counter clockwise while the belt cycles clockwise around the pulleys. Saw it described on a site as this: “If it's a serpentine belt and wraps around the pulley from the underside, it's probably spinning the fan in reverse.”
I just replaced my water pump and fan clutch in a 2008 I5 with the following from RockAuto:
Water Pump: ACDelco 252822 ($33)
Fan Clutch: HAYDEN 2787 ($43)
I generally do not like to stray from OEM/ACDelco when replacing parts but didn’t think it would be too big of an issue with the fan clutch. Plus, it’s less than half the price of OEM. And if you check the specs on the OEM clutch in RockAuto, it specifies the rotation as “counter clockwise.” Not sure why the titles are written the way they are with some specifically calling out reverse rotation and others not but you’re good if you go with any of those options. No complaints with my units so far. Regulates temps just fine, although the fan seems to stay on for a slightly longer period of time when I drive it after sitting all night. Don’t remember my old one doing that or me noticing the extended time but it settles down and doesn’t cause me any issues.
Replacement wasn’t difficult either but you’ll need the removal tool from your local auto parts store if you don’t plan to buy one. And everything I read mentioned the need to replace the water pump AND fan clutch together. Just throwing that out there in case you were only going to do the fan clutch. Might also plan to do it over the weekend or a few days where you won’t need to drive it so that you can properly flush the coolant with distilled water. Flushed mine 3 times before getting the replacement parts installed. Simple, but not a quick process by any means.
