I never go over 190 when I wheel but I also have the aux fan wired to a switch. As far as gas mileage tanking I wouldn't doubt it. But then again I'm running 33's on 3.55 gears. My jeep is daily capable but it's mostly a trail rig. My mileage is bad already but I'll take cooler temps over a few mpg 's any day. And by no means am I saying stock is inefficient but a zj clutch is an old upgrade with proven results.

HD fan clutch for the XJ (posts #6, 3). Moves more air than standard but is not jet engine loud like the ZJ fan. Also does not lower fuel economy as much as the ZJ fan.

After doing some searching I believe the ZJ standard duty fan clutch, and the 2.5 4cly fan clutch are the same part.
The NAPA website shows that #272310 has the following applications: https://cimg4.ibsrv.net/gimg/www.che...cb7d52c419.png |
NAPA online shows this part as the only application for 4.0L 1993-1998 (ZJ) Grand Cherokees. V8 ZJs use a different mount:

Rock Auto lists these parts for 2.5L XJs. It appears that the Hayden 2737 part that the OP mentioned in his first post is interchangeable with NAPA #272310:

if you look on Rock auto the standard duty (without Max cooling) ZJ and the 2.5 4cly fan clutch are the same part.

Got me thinking here.......
What if we could get the electric fan to just come on sooner? Automatically..... A different fan switch is available for Renix. |
That would be a great option, especially for '00/'01. 223 degrees is a little high, IMO.

I must be losing it. I don't see any applications on Rock Auto for the ZJ that don't say "severe duty" or "heavy duty/max cooling".

A manually operated switch override would be helpful for only those times you really need it though.

OMIX-ADA 1710504 is the listed under the 4cyl Cherokee or the ZJ without heavy duty cooling.
