It's toward the passenger side on an NAS LHD truck (as you face the truck staring over the radiator). Ive done it about 10 times in the past 4 mo on my 4.0, a 4.2 (LWB) and a 3.9 (SWB) while playing with different fan clutch options.

Passenger side? Seriously? So confused...

Anyhow, one thing that may not be recommended - but certainly felt good - was I just decided to take my big 5lb mallet and smashed the existing fan right off! Well, access is no longer an issue . Also made me feel a bit better...

Sweet baby Jesus wearing a tuxedo shirt...it's off.

For those wondering - passenger side to driver side to loosen the viscous fan clutch (i.e. clockwise if you're standing in front of the vehicle facing it). Which is what I was doing all along...it just wasn't cooperating.

The remnants of my bashing...literally the only way to get this thing off was to bash the fan blades and get better access and use a pipe wrench on it with the handle of my floor jack on the end of the pipe wrench for leverage. Insane. The downside is I'm pretty sure I'm probably due for a new fan clutch now, which I don't have, and takes me out of the running for heading to Jeff Huffs' tomorrow.

I'm also pretty sure I nicked a belt or two while in there, and tore up my AC pulley pretty good .

The video would have just been a bunch of headbutting, unintelligible profanity, and bits of fan flying everywhere while I smashed it with a hammer. Actually that probably would have been pretty good.

I'm not even sure there's enough fan bits to hang in the garage but I'll give it a place on the wall of shame next to the broken drag-link end from Rausch.

I have a long way to go to catch up to Huff's collection of broken bits though.

For the posterity...

You should loosen it the same direction it spins when the truck is running.

As the cause of your repair, I am sorry, but in any event, it is better than a dented hood and busted rad.

Ronald don't apologize! It needed to be done...I'm not one to drive around with sh*t unfixed - so you were not the catalyst, but you were a voice of reason. I'm very much happy it's off and the new fan it on. I'm just not happy that it took 2 days .

Missing a fin would not be good for the waterpump either as the fan would be spinning out of balance, and if it grenaded and took out the rad and hood we'd have an "I told you so" situation on our hands, which in my opinion is much worse. I actually appreciate your input and kicking me in the arse to get it done. If it wasn't a love/hate thing with Rovers I wouldn't own 4 (cough, cough...5 : ).

I feel bad when I say something is easy and then this type of thing happens.

It's Rovers man...it's always the ones I over-prepare for (replacing the injectors in the Tdi for example) that end up taking 45minutes to fix. And the simple ones (replacing the fan on the V8) that take 2 days. Me (and my wife...as she knows where to find me at least...in the garage) are used to this business!

It's funny though, I was determined not to let a second evening go by where I had to go to bed mad at the truck. I was going to get that thing off tonight come hell or highwater. So when I took one look at the 5lb hammer sitting there it seemed like it was now or never to start smashing things . Worked out in the long run...

Just saw this thread. Can't believe Jason did not write this the first post... Someone needs a vacation.
It's pretty much the same for anything that turns: you don't want it to fall off/unscrew itself. Turn the engine on, check which way the fan turns and turn in the same way to unscrew!

Pretty much did this the entire time....wasn't until later I got mixed input. Regardless it was still on there like a b*tch!

That's what I'd be saying if I was posting after the resolution had already been determined, too. haha.

Let's face it - Jason wasn't going to get this fan off no matter which way he tried.

This was what I meant to type before iPhone auto-corrected.

It is supposed to be reverse - from what I remember you can cheat by turning the car on and seeing which way the fan turns, and (of course turn the truck off) then use the wrench to loosen in the same direction it was just spinning. When tightening, don't make it too tight, as it'll continue to tighten as the fan runs.
