    Hello fellow P38 enthusiasts! My 1999 Bosch P38 is suffering from a seizing VCU. I have been looking for a new replacement but seem to come up empty handed. Does anyone have a link or recommendation for a replacement VCU? Thanks in advance. -Oats
  2. Possible engine damage. Coolant system, water pump, viscous fan, serpentine belt fail

    Possible engine damage. Coolant system, water pump, viscous fan, serpentine belt fail Hi everyone, I think I have really goofed. I was taking my 98 P38 HSE on a long road trip (she always loves to break down on the long trips far away from home) and I started hearing a strange whining noise...
  3. Viscous coupling gone or going..

    Range Rover Mark II / P38
    Been noticing some issues. Vibration on turning, heavy steering, occasional chirp from front tires, and ABS triggering, and heavy tire wear on inside and outside of front tires.. Gets worse when hot or driven for a while. My diagnosis is pointing toward the viscous coupling in the TC is toast...
  4. Fan Viscous couplnig

    Range Rover Mark II / P38
    Hi, I was told by a mechanic that a fan VC should always be held vertically (the installed position.) On another forum (BMW or OMEGA, can't remember) too confirmed this. I was going to purchase a VC for my diesel rangie and saw that the seller has stored it horizontally. So didn't buy. Can...
  5. Anyone installed electric fan(s) in an early RRC in place of the viscous fan?

    Range Rover Classic
    Anyone installed electric fan(s) in an early RRC in place of the viscous fan? To cut a long story short my fan shattered while I was on the freeway and ripped my radiator apart. All else appears okay in the engine bay, I managed to get the vehicle off the road before the engine overheated...
  6. DSE viscous fan- what's a good one?

    Range Rover Mark II / P38
    So..... hot on the heels of my cracked windscreen and ruptured prop shaft coupling, my viscous fan is now failing. Very high temperatures being reported by the binnacle thermometer when climbing and so on..... I check and I find that even though the DSE runs the BMW M51 diesel, the viscous fans...
  7. Classic P38 4.0 Overheating Saga

    Range Rover Mark II / P38
    Hi Folks excuse the first post as always the worst. Picked up a 2000 4.0 SE which I think has turned out to be a pup. Did 150 miles without issue and then 10 miles from home and the temperature swings wildly into the red and expansion tank kicking out what was left of the coolant (muddy water...

  9. Viscous Fan blew up

    Range Rover Mark II / P38
    Hi all, Yesterday the viscous fan on my 4.6 '00 blew up under mid acceleration to enter the highway, as a result I have multiple "ninja stars" nailed on my brand new radiator :shock:. I switch off the engine immediately so no overheating at all (at least I think so). At the very moment I...
  10. 2004 TD6 L322 - Viscous Fan Bi-Metal strip

    Range Rover Mark III / L322
    Hi Guy's, I have a 2004 TD6 (I had 2 V8's previously). Anyway, I've heard many people describe the sound of the viscous fan like a 'hovercraft' and although some of you may not like this, I actually love that deep throaty sound! So anyway, my question is this, I though I'd bend the bi-metal...
  11. Electrical or Viscous Fan issue

    Range Rover Mark III / L322
    I am having issues with a 2006 Range Rover HSE. I have been to two shops and they don't seem know what to do. There have been several fault codes but the consistent one is that the computers aren't talking to each other. The general consensus was that the alternator was going bad and causing...
  12. Viscous Coupling test

    Range Rover Mark II / P38
    Having read stacks of viscous coupling threads in the search section here are my results. I put the automatic transmission in neutral, applied the parking brake and jacked the passenger front wheel off the ground. With a torque wrench set to 60 ft lbs I was able to turn the wheel 90 degrees...
  13. Transfer Case Viscous Coupler

    Range Rover Mark II / P38
    Mine is starting to seize. I did the one wheel off the ground and it took me standing on 4 foot bar to turn wheel. What is the best source for a new one? Or should I pull the front shaft and forget about it?
  14. Can't get viscous coupling out

    Range Rover Classic
    I have the t-case housing loose and it is spinning several inches back and forth but I can't get the VC to release from its attachment point. The housing is only separating from the t-case by a tiny sliver and I can't really get anything (pry bar, screw driver, etc.) between the two areas to...
  15. What size is the output flange nut on the viscous coupling unit?

    Range Rover Classic
    What size is the output flange nut on the viscous coupling unit? My largest socket (1 1/8") is too small and I need to go buy a bigger one but I can't find in the WSM or on any postings that say what size it is. Does anyone recall what they used when tackling this project? Thx, John

  17. Viscous fan running all the time

    Range Rover Mark II / P38
    Hi, my problem: the viscous fan is running all the time, even when the ambiant temp is below 0c. already replaced: viscous fan, waterpump. i think my radiator is bad, because when i feel on the 2 top hoses, they have the same temp, so i think my rad is clogged and doesn't cool very much. cold...
  18. Viscous Coupling Bearing Fitment?

    Range Rover Mark II / P38
    Hi I've removed the VC unit from the transfer box. I used a tri leg bearing puller to push the VC threaded shaft through the bearing and then pushed the bearing from the housing. Pretty straight forward but I'm wondering what's the best way to push the VC shaft back through the new bearing...
