Stupid_fast Posted June 4, 2013 Report Share Posted June 4, 2013 I'm looking for the OEM nissan (branded as Atsugi, or paraut?) pump with fan clutch part number, I think I've found it but the last one I got was for the larger size/later model fan and I don't want to order the wrong thing again. Part number I've come to is Paraut W0133-1616465 ... Is that the correct one ? I can't find an exact picture of any of them, I need to make sure I get the right size fan clutch. I really have no idea what the fan year/model it was off of. I got it with my 'rebuilt' L20b and of course I was an idiot and replaced the old atsugi cast one with a kragan stamped impeller one with the impression 'new is better'. I have the head off and everything apart I wanted to fix my mistake and get a proper cast/curved impeller OE pump w/ the fan clutch. Thanks... 1 Quote Link to comment
Eagle_Adam Posted June 4, 2013 Report Share Posted June 4, 2013 if you still have the old one, i have a fan that will fit... Quote Link to comment
INDY510 Posted June 4, 2013 Report Share Posted June 4, 2013 LOL ... I'm still driving around with my leaky water pump ... . these were the part numbers you gave me in my status update StupidFast: . Atsugi # 11238004035 NISSAN #21010-23028 I think I have the smaller non-A/C type fan ... .. but Phil had to cut the blades smaller to fit a PL510 ... .. does a non-A/C fan fit a 510 without trimming the blades?

FML! Thats the incorrect one! At least for my setup... This is for the larger fan, the one I have doesn't fit on this clutch. If anyone wants it before I return it I'll give it to them for $40 !

Eagle_Adam Posted June 4, 2013 Report Share Posted June 4, 2013 or i could sell you the right fan for cheap.... Quote Link to comment
Stupid_fast Posted June 4, 2013 Author Report Share Posted June 4, 2013 There would be no clearance to my radiator. Last time i looked this style sticks out a bit further ... Quote Link to comment
datzenmike Posted June 4, 2013 Report Share Posted June 4, 2013 There are two pumps usually with two different fan sizes. L20B left and Z20/22/24 right. The L20B air con may also use the right one??? L pump has smaller internal impeller and cavity to match Z series has much larger impeller and cavity to move more water. You do not want the stamped replacement. This is for a Z24 but is pathetic.

Eagle_Adam Posted June 4, 2013 Report Share Posted June 4, 2013 oh, so you need a WP with no fan clutch? cus i have one of those too :P Quote Link to comment
Stupid_fast Posted June 4, 2013 Author Report Share Posted June 4, 2013 @datzenmike, the L20b one on the left is what I was running before, but its one with a stamped(pathetic) impeller. The problem is a lot of the incorrect ones list as compatible to Z and L cars even if they're not !! Is the paraut(atsugi) part no. I listed correct? I think it is but I don't want to buy the wrong thing again. @Eagle_Adam, No, the fan clutch and fan I have now fit just fine ... this setup works fine I just want the better cast impeller pump !!

Stupid_fast Posted June 4, 2013 Author Report Share Posted June 4, 2013 That's what I wanted, thanks Mike !! FYI nissan OE is Atsugi... So I can usually get the part numbers from the nissan one. Quote Link to comment

Stupid_fast Posted June 5, 2013 Author Report Share Posted June 5, 2013 @Hainz, This looks like it ?? Expensive. PARAUT is a sub brand of ATSUGI, you can still get them around too. http://www.ebay.com/itm/Nissan-Engine-Water-Pump-Atsugi-112-38004-035-/180967884069?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item2a2286c525 Quote Link to comment

pondking Posted November 23, 2013 Report Share Posted November 23, 2013 whats the purpose of a fan clutch? Quote Link to comment
datzenmike Posted November 24, 2013 Report Share Posted November 24, 2013 No matter what the engine or water pump speed the fan is limited to about 1,500 RPMs. If overheated the thermostat control can raise it to 2,300 RPMs. At most speeds above 30-40MPH a fan isn't even needed as vehicle speed will be sufficient for engine cooling. A clutch fan reduces the load on the engine to drive the fan unnecessarily. The fan is quieter also. Quote Link to comment
pondking Posted November 24, 2013 Report Share Posted November 24, 2013 so its more of a cooler and fan helper when idling Quote Link to comment
datzenmike Posted November 24, 2013 Report Share Posted November 24, 2013 Not really. The fan does not need to turn that fast at higher speeds. Some slight energy is saved and MPG gained and quieter operation by letting it slip. It doesn't cool any better that a solid mounted fan. Quote Link to comment

It doesn't cool any better that a solid mounted fan. unless the new fan has more blades stock L16 4 blades clutch fan 7 blades wouldn't this have to pull more air then a stock 4 blade Quote Link to comment
datzenmike Posted November 24, 2013 Report Share Posted November 24, 2013 Don't forget that it slips. Maximum speed is around 1500 RPMs. The extra blades average out at idle Quote Link to comment
