the sucker king Posted January 12, 2013 Share Posted January 12, 2013 Rock auto shows the same pumps fitting both engines. I need one for an '86 ea82 wagon. Quote Link to comment Share on other sites More sharing options...
MilesFox Posted January 12, 2013 Share Posted January 12, 2013 Thy are different although the bolt pattern is the same. for 85-89 you will get ea81 and ea82 cross referencing since both bodystyles overlapped those years. when in doubt, ask for one for a 94 loyale to weed out ea81 cross references. Depending on if you have mpfi or not you will want the 110mm or 105mm water pump. 105 for mpfi and 110 spfi, carb You can tell by looking at the pulley. IF the pulley fits over studs, it is the long water pump. If the studs are on the pulley and the pulley bolts to the water pump, then you have the short one.

Thanks for the info, rock auto list the same pump will fit specifically OHC and OHV on some of them so I guess they are just wrong. Quote Link to comment Share on other sites More sharing options...
skishop69 Posted January 13, 2013 Share Posted January 13, 2013 EA82 has a longer 'snout' to make up for the timing belt spacing. EA81& EA82 water pumps are not interchangeable to my knowledge. Quote Link to comment Share on other sites More sharing options...
