Here you go. You can see the fresh cut marks on the holes I made.

Ok. I got some miscellaneous stuff done tonight. Replaced both front brake lines. Might do the rear later, but it's fine for now. Re-installed the brake pedal, adjusted the brake light switch and vacuum bled the brakes. I still need to bleed the rears, but might not do that until I replace the rear line.

Here's the fan situation:



There's pretty good contact on the upper radiator hose. Even if there was a shroud there, it might still be an issue because the contact is right at the radiator inlet neck. I have to do some homework an see if I can fit the Taurus fan with 4.25" of clearance. I don't think it will clear. I can shave the water pump pulley snout a little, but not much.

I have 1.5" between my radiator and fan clutch.

Clearance from the fan and clutch shouldn't be a problem, looks like you have plenty of room in that regard if you have that much front to back movement in your drivetrain I think you may have bigger issues :laugh

I'm thinking with the shroud and ZJ fan you would be fine as far as clearing the hose, here is a photo of a ZJ mechanical fan and tj shroud with a Dakota upper hose... The fan blade looks like a non issue with the shroud

Not worried about the mechanical fan clutch clearance to the radiator, that looks fine. It's the interference with the upper radiator hose that I think will be a problem, even with a slightly shorter ZJ fan.

The article that went with that photo also said the mechanical fan was from a 5.9 ZJ, which I don't think exists.

Think the 5.2 fan will bolt to the Ram fan clutch?

The 5.9 limited ZJ did come with a mechanical fan till 1998 the 5.2 and 5.9 were the same fan blade setup, and yes the Dodge clutch will accept the ZJ blade. The 4 bolt pattern is the exact same

Here is a pretty good indicator that the ZJ came with a thermal clutch fan (mechanical) from 94-98
And that they used the same clutch, and fan.

Confirmation that the fan clutch will work with the different fan blades....

Just so you know I'm not guessing with the advice or knowledge

The 5.9 was only made in 98. Wiki says 5.9s had and electric fan. The 5.2 always had a mech fan 93-98.

Yeah, despite what the parts books say, I think this is the case.

I'm going to take the fan shroud off my 2005 and see if it will work and where clearance issues are. The junk yard I was going to go to is closed on Saturday. If the fan clutch bolts to the ZJ fan, I'll just do that. I can find them on ebay for $35 or so. My specific engine (2000 Ram 5.9) isn't listed in the link above, but I think the point is one-size-fits-all.

Jason, have you considered trimming the tips of the fan blade from your dodge fan? If you were to scribe a line that followed the curve and took off the 3/4" or so that is over the ZJ fan, you would not lose the pitch of the blade or it's effective cooling, you'd gain the extra blades over the ZJ 5 blade fan, which ultimately would increase cooling regardless, you'd be into it under an hour with the only tools really needed being a marker or scratch awl, a pair of aviation snips (red or greens would work, just determines the direction from which you start the cut) or a cut off wheel, and a grinder to smooth the edges when you are done. You know now the measurement for the blade, you have a shroud you can use to verify fit, and you already have the Dodge blade. Why not give it a shot??

You know, I had that same thought late last night. I've got snips that would work. I might give it a go. The Dodge fan is a 5 blade as well. That would at least get me cooling.

It occurred to me when reading the posts this morning, the Durango blade I had was definitely 6 blades as memory serves me, the pitch of the blades in either setup will determine the cfm, so trimming the blade length along with a shroud and a much smaller surface area of the radiator I would think you'd be ok for cooling.
If you add a winch or want extra cooling you could always fit up a small pusher fan

Alright. Here's what I got.

My 6 cylinder fan shroud is spaced about 1" from the upper radiator inlet. Remember the Dodge fan contacted the upper hose, so I'd need to shave 1"+ off the fan.



Here's the Jeep 4.0 fan next to the Dodge 5.9 fan:



The Jeep fan is 9.25" from the center of the clutch to the end of the blade:



The Dodge fan is 10" from the center of the clutch to the end of the blade:



I tried putting the Jeep fan on just for fitment, and it contacts the top of the fan shroud. I measured from the threaded snout on the water pump pulley to the top and bottom of the shroud and it's way off. 8" to the top, about 10.75" to the bottom. It's as if the engine is sitting way too high. The engine mounts were installed exactly as AA spec'd, and as low as I'd ever want them. In fact, they are a little too low for my liking, but I wasn't going to try to move them.

So even if I cut that Dodge fan down to 9" or less, that leaves over 2" at the bottom of the shroud open with no fan blowing across. I'm not sure what affect that would have on my cooling? I have a little room at the top where I could move the shroud up by redrilling the holes, but I'd estimate that only gaining me about 0.5".

Thanks! I got tired of fussing with the fan, so I took the grille apart and painted it.
