Water Pump

Featured Replies

Look a the distance from the pump body to the bottom of the pulley hub.

 

If there is barely any (3mm or less) of exposed shaft between, then you have the shorty (105 mm)

 

If there is a longer section (7-10mm)of exposed shaft section, then you have the long one (110)

 

 

The other indicator is the type of pulley your car has bolted onto the water pump.

 

If the pulley has 4 holes to bolt onto the hub, and an additional 4 studs that are for the clutch fan, it is meant to be used with the short (105mm) pump.

 

If you have the simple pulley, that just has 4 holes to slip over the studs, adn then the clutch fan slips over the same studs....then you have the 110mm pump.

 

IMO that the 110 mm pumps are much more common.

I was also told it came down to what type of ac system your car has installed. picture.php?albumid=52&pictureid=922

Pretty sure this is the dealer installed A/C system not the factory.

it's been awhile since i've dealt with this but pretty sure milesfox has a good write up on determining which one you need, i know i've referenced it before.

 

just do an EJ swap. LOL

With the big tires on it now i really want to do the ej. Maybe when i get a house ill tackle that little project. But not in an apartment parkinglot.:)

If the waterpump pulley slips over the studs in the pump, then the fan slips over the same studs, you have dealer installed A/C. Long Pump (110mm)

 

IF the waterpump pulley is bolted to the pump, then the fan slips over a second set of studs and bolts to the pulley, you have Factory A/C. Short pump (105)

 

 

Again. it's easy to just look. If the hub is barely off the body of the pump, it;'s the shorty.....if there is a centimeter or more of space with shaft showing, then it;s the long.
