grasscutter96 Posted March 7, 2018 Share Posted March 7, 2018 Need a water pump on my 1984 1.8 GL Subaru dealer can still get an OEM for $109. Local parts store has them for under $30. Had a bad experience with aftermarket water pump on a 93 Camry. Overheated, took aftermarket pump out (was only 3-4months old), and ordered an OEM. Compared the 2 side-by-side and wow what a difference. The water vanes on aftermarket were 1/2 the size, and had less total vanes. Put OEM back in and 100k miles later working great. (Over 300k and still running today) Anyone have any input on this subject, on theEA81 engines? Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 7, 2018 Share Posted March 7, 2018 Based on ea82s. I've had good luck with the best quality option at napa. Iirc, they were around 50 ish. $30 sounds way to cheap for anything decent. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 7, 2018 Share Posted March 7, 2018 I re read your post... if the original oem one lasted 300k, get another oem one. Probably good for another 300k. Quote Link to comment Share on other sites More sharing options...
Sapper 157 Posted March 8, 2018 Share Posted March 8, 2018 (edited) I wouldnt spend that money on an OEM Just go with either a cardone select P/N 5573512 or an AISIN P/n WPF005 I have used both and the first lasted over five years, and then I replaced it with a cardone. EDIT: sorry the text is doing this wierd highlight thing, I copied the P/Ns from rockauto and cant firgure it out lol Edited March 8, 2018 by Sapper 157 1 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 8, 2018 Share Posted March 8, 2018 OEM is cheap insurance. $109 is nothing compared to the frustration of doing it again. But we charge $99 an hour for labor so the math really easy if you consider the potential loss in doing it twice. If you time and labor is worth less than the difference in price.... $79.... then I guess go with the $30 junk. GD 2 Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 8, 2018 Share Posted March 8, 2018 not a performance application so I wouldn't bother with the OEM unit unless you're working the engine hard in situations such as offroading. If it's a daily you wouldn't need the better flow/efficiency of the OEM unit as you wouldn't see the high revs regularly or for long enough for the cavitation that can occur to do any damage. That said, if you want the most efficient cooling system the OEM unit would be best to use. Your call. CheersBennie Quote Link to comment Share on other sites More sharing options...
BEECHBM69 Posted March 10, 2018 Share Posted March 10, 2018 AISIN makes a good product. Cast impeller vs stamped. I've used both the EA81 and EA82 versions without issue. Dan 1 Quote Link to comment Share on other sites More sharing options...
Knucklehead Saloon Posted March 11, 2018 Share Posted March 11, 2018 Aftermarket had a way better impeller design than oem on my ea81. Way bigger vanes. 1 Quote Link to comment Share on other sites More sharing options...
