This is a dumb question, but the fan clutch shouldn't be engaged at start up when the truck is cold right? And a normally operating clutch is easy to spin when the truck is cold, but should be harder to turn when the motor is warmed up, correct?

Also, has anyone ever heard of a bad VC fan clutch making a sound kind of like if you stick a card into a house fan type noise?

My D2 has developed a sound like I described above (card hitting fan blades) over the past week, but I haven't really had time to figure out what is making it because of school plus it's been raining all week here. It's coming from one of the components on the front of the motor, I'm just not sure which yet. Hopefully tomorrow I'll be able to hunt down whatever is making the sound, but I'm just seeing if you guys have any ideas...

It's not rubbing anything, when I was looking around earlier today I check that (hoping it was just that).

Also the sound has gotten a little louder everyday. I could hear it all week, but it wasn't loud enough for me to really think about it until this weekend...

My fan would hit my shroud and make that card in the spokes sound. The problem was a water pump bearing that had about a 1/2" play. You may want to take off your serpintine belt and check the water pump.

I also had recently a bad fan clutch(only 7 months old-all makesPOS)that would sound like a 747 at startup but then would never activate again even at 210 degress.

Strange thing... this link mentions part #2991, while Napa and Kragen's search turn up part #2772 for a 95 Classic with a serpentine belt... Which one it is?

Mike - does this fan engage and disengage the same way as genuine LR clutch does? I have a P38 fan clutch on the LWB, and that one never seems to disengage.

Funny you should mention the water pump, recently I've been wondering if it's leaking some on my truck...

Well that's another thing to check...

It will fit but you will have to get either a DI or early DII fan as the '03/'04's are one piece units ie fan and clutch.

so is RND302 from rovers north, money no object stock fit OE... a direct replacement?
incl fan?

what is the pn and cost of a LR OE fan/clutch unit? Mine lasted 4 years and 70k miles, if another lasts as long I'm fine with the costs..

dont want to drill or deviate from factory on this part, just my choice

I just wanna replace whats there with the exact stuff, if its a one pc setup now, thats what i want to put back(stupid perhaps but fine with me)

Yeah Gem yours is an all in one unit. You can't seperate fan from clutch. I ran an '03 one on my truck for awhile. No difference in performance from the seperate clutch fan combo from earlier DII's.

If anyone is interested I have the one from my '00 D2 left over since the TDi instal - free for the taking. :)

Help me a little with the shipping, owe me a beer when we meet someday or something - anything - I just hate to see it sitting here and don't want to bother putting it on Ebay. I'd rather "give" it to a fellow board member in good standing here.
