According to this http://www.peachparts.com/shopforum/diesel-discussion/189747-viscous-fan-oil-viscocity.html it's supposed to be 10,000CST.

Re: [MBZ] Fan Clutch Modification
There are seals between the halves of the clutch and on the shaft. Usually the shaft is bad, I suspect, and you'd have to find a proper seal, I don't know of any kits.

Re: [MBZ] Fan Clutch Modification
Two points on the fan clutch -- first, the fluid leaked out originally, it's very very unlikely the new fluid won't. You should buy a goodly supply, as you will be doing this again pretty soon unless you take it all apart and replace the seals, which is what's wrong with it. Second, clean your AC condenser and radiator. Lotta crap in there even though it looks clean. I replaced the condenser on my TE last fall, it was punctured. Looked pretty clean, just a bit dusty (I live next to farm fields,eh?). Ha, held it up the the light and it's almost completely occluded. Engine temp dropped quite a bit with the new condenser, even with the AC on. Get some evaporator cleaner and clean it, should help quite a bit with lowering operating temps.

Re: [MBZ] Fan Clutch Modification
Ahhh, so the pin comes out, allowing you to fill through the hole it is located in. Got it. I'm not terribly keen about modifying the bimetallic strip, no matter what Stu says, despite wanting to do everything I can to keep the temps down. I will probably just try and fill it as much as I can and live with that - worst case scenario would be that the fan is on when it's cooler, which isn't a big deal. I am planning on doing the resistor addition to the aux fan circuit as well. That should help with under hood temps, too. No problems with cooling, just wanting to get ahead of the seasons down here so it runs as cool as possible, that's all. Going to the stealership tomorrow to pick up a couple of gallons of the new blue coolant. Found my former parts guy is still there and willing to sell to me at very good prices. A gallon of coolant lists for $31, my price is $23. Nice.

Re: [MBZ] Fan Clutch Modification
That silicone oil was hard enough to get into the differential of my RC truck, but I think I used 10,000 CPS. I have a bottle of 50,000, and it's nearly Solid! I think it's available in 100,000 and 500,000 viscosities which would nearly lock up the gears. The toughest part was not to get it onto anything including clothing since it's so hard to get off!

Re: [MBZ] Fan Clutch Modification
If you remove the bi-metallic strip and the pin, you can add oil through the hole the pin came from. I used 3000 cps viscosity silicone oil, got a really small bottle at a hobby store.

Re: [MBZ] Fan Clutch Modification
I may look into this next week, as I am off for the week for spring break. I don't like the pin modification, as it is permanent and the fan clutch is a rather pricey part. I figured I would check on the fluid as well. Can you expound on this some more? I seem to recall some discussion about fan clutches and checking/adding fluid, but don't recall the details.

Re: [MBZ] Fan Clutch Modification
Looks easy enough. Two methods are discussed, adding a bolt and shortening the pin. You could undo the bolt, and if you had a spare pin you could restore the original, so neither modification needs to be permanent. On my '95 E300, I refilled the clutch with oil, that worked for me. -- Max Dillon Charleston SC '95 E300, '87 300TD, '73 Balboa 20 Dan Penoff wrote: >Anyone ever try this? > >http://www.k6jrf.com/MB_vfc.html > >I see that it's originally from Stu, meaning that it must be relatively >safe. > >Dan > > >___ >http://www.okiebenz.com >For new and used parts go to www.okiebenz.com >To search list archives http://www.okiebenz.com/archive/ > >To Unsubscribe or change delivery options go to: >http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
