Om617 96 Jeep Cherokee build thread
#102
I went back and forth on this for a long time. Mechanical vs electric, a mechanical fan will always move more air at equal RPMs then an electric. The problem I encountered was 1: the Mercedes mechanical fan did not lock up at lower RPM. 2: only the upper portion of the fan pulls from the radiator so the clutch is not exposed to the hottest air, thus contributing to problem #1. 3: I could not find a cost effective way to properly shroud the fan. All of the above never led to an overheat situation, what it did cause was big temp fluctuations. The electric fans solved the fluctuating problem and ultimately pull more air through the radiator and condenser at idle and low speed due to constant RPM and proper shrouding. I highly recommend the electrics for this combo. Hope this helps.

Just read through your whole thread, im very impressed with it! Your the first person that ive seen be able to use the original tachometer.

Hey evenglass I have a 1986 Comanche and I'm doing the Mercedes swap. I'm not really sure how to come up with a plan on the engine mounts. And also I want ac cause I live in palm beach county. So I don't know exactly how I'm going to create a bracket like u did. Do you have any drive line vibrations or any deliverability issues from the swap? Any advise would be greatly appreciated

With the AC just keep it as tight and high to the left side of the block as possible.
No vibes or driveability issues at all. Just make sure you gear appropriately basically lowest gears possible 4.56 or 4.88.
You're welcome to come drive and see it if you want, im in Highlands County not far from you.
