Alright, in an effort to save people from the dreaded disintegrating plastic fan, I'm trying to spread the word. I could 'cut-n-paste', but it's easier if you just click here: http://www.pirate4x4.com/forum/showthread.php?s=&threadid=143333 There's a bolt-in replacement for the Rover factory fan. You know, the one that's made out of plastic that you hear horror stories of disintegrating and completely taking out a $600 radiator? Yeah, that's the one. Anyway, the part number is: Imperial Automotive Products 18 inch fan 20618 Read the thread and decide for yourself if the damage is worth the risk... Later, Michael | ||

Why not just take that mechanical fan out and slap on 4 Renault fans worth 6$ each and have them routed to the thermostat and a control swith on the dash!  | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 45 Registered: 04-2003 |
Because this is easier and better. Also, Renault is French. | ||

LOL...now YOU are a purist??? | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 46 Registered: 04-2003 |
No, I just hate the French. Love their fries though! ;) Besides, this 'mod' isn't exactly for the 'purist'. Did you notice that you have to actually go to AutoZone to buy it, and you will probably install it yourself? No purist I know would do that. They'd have it flat towed to the dealer and have them fix it 'right'. | ||

Thanks for the tip Michael, just picked one up will go on tonight, with my luck my fan blade will go through my radiator or hood on the drive home. | ||

Nadim, BME, no combination of electric fans is capable of keeping the rover cool on highway grades in SoCal. peter | ||

Hey Michael what tires to you run again?? You know BFG is owned by 'the french' don't you?? Plus I thought they were called 'freedom fries' or whatever now LOL | ||
| Carter Simcoe (Carter) Senior Member Username: Carter Post Number: 504 Registered: 04-2002 |
seriously though, awsome find w/ the fan. I'm going to go pick one up as soon as I get a job. | ||

is that a RR fan? Same for the D1? | ||
| Robert Sublett (Rubisco98) Senior Member Username: Rubisco98 Post Number: 853 Registered: 04-2002 |
I recently busted one blade off when I lost the idler pulley and the serp. belt wrapped around the fan, and have been meaning to replace my fan as well. If it will work for a D1, I'll be doing that this holiday weekend as well as many other things to the Rover. | ||
| Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 765 Registered: 09-2002 |
Blue, it should be the same. It's the fan, not the clutch. | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 47 Registered: 04-2003 |
I posted this in the Disco section because I felt that: 1. Most RR owners read here too. 2. Most Disco owners don't read the RR section 3. That the Disco1 and RR1 fans were the same??? I could be wrong, but I don't think so. I don't know about the VC though. Anyone have an answer if they are the same on the Disco1? | ||
| Carter Simcoe (Carter) Senior Member Username: Carter Post Number: 509 Registered: 04-2002 |
I've got the manuals for each and the fan is described in both of them as "11 blade axial flow 433 mm diameter". I guess It might attach to the viscious coupling in a different manner or someting though. | ||
| Alan Bates (Alanb) Member Username: Alanb Post Number: 184 Registered: 07-2002 |
FYI: I just put one on my 92 RRC, fits great on the back of the VC, the 18" fan diameter is larger than the stock 17" diameter and I had to slightly trim the plastic fan shroud so the blades wouldn't touch the edge of the shroud, no big deal, just don't put your fingers too close. Check your fan blade closely, I had stress cracks in mine, don't know how much longer it would have lasted. Thanks again Michael for the tip. | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 49 Registered: 04-2003 |
glad to hear people are doing this. I think we all might be surprized at the condition our fans are in. It also surprizes me that Alan had to trim his shroud. I did not have to trim mine. I think that whoever does the conversion should post thier 'issues' and then give a little feedback to the noise issue and any additional cooling (either percieved or measured more accurately than the factory guage). M | ||
| Alan Bates (Alanb) Member Username: Alanb Post Number: 185 Registered: 07-2002 |
Due to the lousy land rover factory tolerances, my shroud was installed at the factory off center in relation to the fan blades, and with the 18" fan it was touching on one side, so I just trimmed the shroud, I probably could have drilled new mounting holes and recentered the shroud and maybe it wouldn't rub, but my shroud is a real tight fit for the 18" fan. Others might not have the shroud/fan interference. No noticable noise issues, no noticable additional cooling, just peace of mind that the fan blade won't destroy something. | ||

Thanks for the tip Michael, it's about the only thing that hasn't exploded yet. I'll pick one up this week. | ||
| michael burt (Mikeyb) Member Username: Mikeyb Post Number: 229 Registered: 03-2002 |
is this a DII fix as well? big week of wrenching, so i might as well check that too... | ||
| Nadim Samara (Discodino) Member Username: Discodino Post Number: 59 Registered: 02-2003 |
Serious One... The French are really great people, especially the busty ones from the south! Good One on the purists towing it to the dealer...HATE seeing a nice looking Landy towed! Peter, In case you haven't noticed, I live in the middle east and travel via my 2 Discos all over the gulf, I "think" that the heat here may be similar to the one you may experience in SoCal. Those nice little 4 fans do the trick... | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1522 Registered: 02-2002 |
Guys, be careful. The Rangie fan turns in the opposite direction of the Disco fan. Make sure the blade pitch is compatible. Peace, Paul | ||
| Milan (Milan) Member Username: Milan Post Number: 206 Registered: 10-2002 |
What happens when that slinky-flex fan hits water? Will it stop or will it gut the radiator when you give it gas? Or will it be like other metal blade fans? I think the stock fan was better for this. Not that the replacement won't work, all my other vehicles have metal fans and ford water easily. Just wondering out loud. | ||
| Greg Hirst (Gregh) Member Username: Gregh Post Number: 196 Registered: 10-2002 |
Paul T.- How is it possible for fan to turn in opposite direction from rangie to D1 since fan is engine driven? I don't believe D1 engine fires reverse direction from rangie. Also, if fan blades were opposite pitch then fan would be "pushing" air rather than "pulling", correct? My 2 cents- | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 50 Registered: 04-2003 |
Actually I think the 'slinky-flex fan' is much more stout than the POS factory plastic one. What you should be asking is 'when is my crappy plastic fan going to shit a blade once it hits water'? IMO the replacement fan will hold up MUCH better than the plastic one. Besides, if you're going through THAT much water on a regular basis you would have learned what a bow wave is and how to properly execute one. As far as the Disco fan is concerned, I think that the same company that makes the metal fan also makes one designed to be rotated in the opposite direction. I can look on my box for the part no's tomorrow. Also, the fan is NOT engine driven, it is attatched to the water pump output shaft and is not hooked to the crank pully. Depending on the direction the belt was fed to the water pump pully there is a definite possibility that the serpentine belt motors could run in the opposite direction. But, I think that the water pumps should run in the same direction regardless of weather it was serpentine or v-belt driven. I don't know for sure though, so check your individual application. I know I double and triple checked mine before I was satisfied the blades were pointed the correct direction. I do not know if this is a DII fix or not. | ||
| Perrone Ford (Perroneford) Member Username: Perroneford Post Number: 103 Registered: 02-2003 |
Greg, It was also my impression that the serpentine belted trucks turn in the opposite direction of the 3-belt older trucks. I have not confirmed this but have seen im mentioned in the past. -P | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1531 Registered: 02-2002 |
Guys, if Discos (and all trucks with serpentine belts) require one to turn the nut counter-clockwise to remove the fan, and those with V-belts require one to turn the fan clockwise for removal, it is reasonable to assume that they turn in opposite directions. Right now, I have a fan from a Range Rover (93) and a Disco (95) in the passenger compartment of my truck (one to be returned to my vendor as it turns backwards from the vehicle for which it was intended)-the blades are oriented opposite. (comment that would have been less kind than I intended removed to maintain decorum) The fans on serpentine belted engines turn in the opposite direction of the crankshaft, while those with V-belts turn in the same direction as the crankshaft.

So what is the proper part number? | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 51 Registered: 04-2003 |
From the back of the box: Part no. Rotation Dia 220618 CW 18 220638 CCW 18 Now I have a question about the CCW turning fan blade Discos. Hows that work if the fan is turning CCW, is the water pump in those trucks different? Must be, because if the fan is turning CCW, wouldn't the pump be turning backwards too? Must be a different water pump. I'm not debating weather I'm right or not, I'm just curious now about the S-belt trucks vs. what I'm more familiar with (v-belt). Hmmm...might have to look at one of them sometime. | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1535 Registered: 02-2002 |
Mike: Remember our discussion on renewing bearings and seals on water pumps? I pointed out the difference between the pumps you had and those I had. The castings are different, the impellers are different, the bearings are different and the seals are different. Peace, Paul | ||
| Greg Hirst (Gregh) Member Username: Gregh Post Number: 197 Registered: 10-2002 |
Paul T.- Ahh yes, since I have an RRC, my less-than-imaginative mind could not comprehend the serpentine belt-driven D1 fan/water pump turning anything other than the same as RRC. I now see the error of my deduction and I appreciate your restraint from slamming me. | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1537 Registered: 02-2002 |
Greg: I have the advantage(?) of being able to see a number of different variations of Rovers on a nearly daily basis. As for the near-unkind statement, I'm not having the best day today. I'll go take it out on the folks who didn't handle the used oil very well in the plant today. Peace, Paul | ||
| Michael Slade (Serious_one) Member Username: Serious_one Post Number: 52 Registered: 04-2003 |
LOL! I just so happen to be draining my oil-catch-pan this very moment! Just what is it I DO do with used oil??? Hehe. Yeah, I'm starting to remember the water pump discussion. Greg H. and I are in the same boat in regards to being cereberally challenged. I don't think I've honestly paid more than 5 minutes attention to the differences between the s and V-belt Rover V8's. You learn something every day I s'pose (if you pay attention). Michael | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1538 Registered: 02-2002 |
To make matters worse, two of yours don't even have Rover engines! | ||

Thank God! | ||
| Milan (Milan) Member Username: Milan Post Number: 207 Registered: 10-2002 |
Well, just to confirm Paul's info. The impelers and fan blades on serpentine belt engines have pitch opposite to those on v-belt driven ones. That's true for all serpentine belt engines I know. While I know how to make a bow wave, things happen. Like falling into a hole deeper than anticipated or bumping into something underwater, stopping the vehicle and then requiring more rpms. That's when the fan blades can bend and gut the rad. Now granted, giving too much gas is a driver error but I was just wondering if the stock blades would fair better. I was not looking for a driving lesson. | ||
| Chris Browne (Chris_browne) Member Username: Chris_browne Post Number: 111 Registered: 02-2003 |
If its a bolt in replacement, there must be a bolt in replacement fan clutch to go with it at alot less cost than the OEM. Anyone? | ||
| tom fransen (Tfransen) New Member Username: Tfransen Post Number: 2 Registered: 02-2003 |
Does anyone know who the fan clutch is supposed to work. My fan does not seem to turn fast enough and my 94 Disco overheats. When I try to turn the fan blade it seems to turn both ways really easy so it looks like it is not catching. | ||
| Jaime (Blueboy) Senior Member Username: Blueboy Post Number: 661 Registered: 02-2002 |
While the truck is cold it should spin freely, when the truck is hot it should lock solid. some other info in the archives as well. Jaime | ||
| charles pastrano (Charles) Member Username: Charles Post Number: 204 Registered: 08-2002 |
That is not true. It will move when hot and it doesnt spin freely when cold. There is less resistance. | ||
| Jaime (Blueboy) Senior Member Username: Blueboy Post Number: 662 Registered: 02-2002 |
charles, let me rephrase my intent so as not to confuse anyone. viscous fan clutch has high resistance when the engine is hot and fan clutch spins with very little resistance when cold. you should feel a significant difference in the resistance between hot and cold. better?? Jaime | ||
| tom fransen (Tfransen) New Member Username: Tfransen Post Number: 3 Registered: 02-2003 |
So if the clutch is not locking at all I can assume that I need to buy a new clutch...right? | ||
| Jaime (Blueboy) Senior Member Username: Blueboy Post Number: 663 Registered: 02-2002 |
tom, the fan does not really "lock" it just becomes very difficult to turn when the engine is hot. so, if the fan turns easily when the engine is hot, the chances are good the VC is bad. Jaime |
