Old man with MJ Posted October 19, 2012 Posted October 19, 2012 Started making a squealing sound,can it be oiled,does it have bearings,most of it looks to be plastic.Are they still available as a Mopar part? 1988 Pioneer with 134000 miles,4.0L 5spd
HOrnbrod Posted October 19, 2012 Posted October 19, 2012 The motor bearings are probably shot, they are sealed so oiling won't help. New fan motors are still available, but for what you pay for one, you are better off getting the whole fan assemble/module replacement from the JY. The aftermarket ones are pretty decent, but get one from the 97 and up XJs as they put out a lot more air (10 blades). The factory p/n is 52028337AC. You'll have to cut off the connector though and reuse your old one if you go this route. http://www.ebay.com/itm/97-01-Jeep-Cherokee-AC-Condenser-Cooling-Fan-6-cyl-/360240001878?pt=Motors_Car_Truck_Parts_Accessories&hash=item53dffa3356&vxp=mtr
COMJNUT Posted October 19, 2012 Posted October 19, 2012 Siliconeintakes.com $25 for a fan that i fit in the stock location with the stock fan shroud and it moves around 1200cfm (more than stock 97 fan, but draws the same amps as oem.)
HOrnbrod Posted October 19, 2012 Posted October 19, 2012 The 97+ 10-blade aux fan moves a proven 1300CFM @ 9A. Just curious as to how you determined the ~around~ 1200CFM and the amp draw for this fan? Also, which size fan did you use in the stock aux fan shroud? EDIT: Just looked at the advertised specs on the site you posted. 4A @ 1250 CFM. Industry rule of thumb for automotive fan CFM is 1A Draw = 100-150 CFM. Best this fan can do is maybe 600 CFM. Offshore fan manufacturers are well known for inflating specs on their products. No way this fan can pull 1200 CFM.

I've seen "industry rule of thumb" been busted before and industry specialists say "that's not supposed not to work like that"...but it is. I would like to see more info on the proven 1300cfm on the stock 97+ stock fan, links please?
COMJNUT Posted October 20, 2012 Posted October 20, 2012 LOL this thread just came up in my google search for the stock cfm's...not able to find it yet...
HOrnbrod Posted October 20, 2012 Posted October 20, 2012 It's over on NAXJA. A manufacturer who sells boatloads of custom three-fan assemblies for XJs using similar fans as yours did real world CFM flow testing tests against the two 97+ fan configuration. All three of his fans' CFM were considerable less than the CFM flow of two of the stock fans. But the amp draw of the two stock fans was more than his three fans, so he used that fact as a selling point. I'll see if I can find it..........
Old man with MJ Posted October 21, 2012 Author Posted October 21, 2012 Thanks for your replies, I will look for one from an XJ (Cherokee?),they are the same size and fit without any modifications?
HOrnbrod Posted October 21, 2012 Posted October 21, 2012 Thanks for your replies, I will look for one from an XJ (Cherokee?),they are the same size and fit without any modifications? Yes, same. If you use one from a 97 and up XJ you to solder on the connector from the old fan.

He measured 2,300CFM for the stock electric fan. http://www.jeepforum.com/forum/f11/electric-cooling-fan-cfm-rating-tests-results-1182706/ If you manage to find one unbroken in a junkyard you should buy it. A brand new TYC 620560 is $60 through http://www.rockauto.com.
HOrnbrod Posted October 21, 2012 Posted October 21, 2012 Yep, that's the one Alexia, from DirtBound Offroad. Gracias. :cheers:
mountainman Posted October 21, 2012 Posted October 21, 2012 The fan i have on my truck, is a dorman.... DORMAN Part # 620001 Its 53.99 on rock auto and is a factory housing. Bolts right on.

HOrnbrod Posted October 21, 2012 Posted October 21, 2012 I suspect the motor RPM vs. HP ratings on the Dorman, TYC, and other offshore fans are nowhere equal to the OEM fans. I'd rather go with a used OEM if you can find one.
