water pump again

[JP]

what's up everybody, i had my water pump changed out with a graf pump and (ultimate kit) and 7 months later it's leaking like whoa! i cant believe it so my question is Hepu a better pump or should i get the warrantied graf pump again, would do oem but i dont want to change again for another 80k if possible,

I bought two water pumps in my haste to solve my "cooling system malfunction" check engine light code.

Now I have two and a timing belt to boot that I never installed since I decided to try a thermostat and it solved my problem! The check engine light never came back on!

IIRC you wrote it was about time to do TB and WP because of high mileage anyway. You are playing with fire. IMHO it would be good idea to change them since you've drained your coolant anyway.

I'll have to double check what brand I ended up getting, but I know that I wound up installing the one with a metal rotor so as to avoid the shattering plastic from the OE

For what it’s worth I have never had an aftermarket water pump with a metal impeller last; everyone I have tried started leaking with a year.

I have tried many brands including Graf, Hepu and NAPA years ago all with the same results. The plastic ones have a bad reputation for cracking / breaking, I think this was true in the early years but materials and the design has changed.I have three VW’s and now only use genuine VW brand water pumps.

I know that almost no one on the forum will agree with me on this subject but do you self a favor and go to the dealer and get a VW pump, the extra money you spend now will be worth the extra cost in the long run.

Please dont start bashing me, as stated just my experence over the years.

I second this motion, My mechanic who happens to specialize is vw/audi says stick with the oem pump. yes they where junk in the beggining but they are better now. Actually get it from the dealer also, the autoparts store ones totally suck (I have done 4 wp's with the dealer having done the current one). the metal ones are not as good as you think, they leak faster and if the prop somehow comes off the shaft......well, you can guess where you are.

the first one i pulled out was oem and the impeller was in pieces, installed graf and started to leak in approx. 7 months going to try out Hepu and take the warranty one and stock it in my closet, just cant believe how a pump could go bad so soon jeez it just mind boggling

Poor bearing quality. Poor casting quality. Poor machining quality. There is more to a waterpump than the impellor.

Check this video and link out; there maybe issues that were overlooked during installation or it maybe defective too... always good to look at all possibilities and take the time to eliminate all possible failure points. Check it out; blauparts has learned allot from selling parts and doing installs in their shops...
