Water pump GRAF or OEM Volkswagen

I picked up a 3.6 brass impeller Graf waterpump for under $50 from www.autohausaz.com they also sell the oem thermostat.

As far as a water pump, the $24 Graf is your best choice. If you need the entire pump....that will cost more. I have also gotten very good water pumps from O'Reilley auto as well.....believe it or not. You probably should shy away from the plastic impellars.

I'd recommend getting a kit like this (...) from idp because it has a Graf pump, which has a brass impeller - some kits use plastic.

id buy the whole water pump, because you dont know exactly where the leak is. i did mine over the winter and in my case one of the inlets cracked badly. I bought this part: 06J-121-026-BG, and even though it had a sensor on one of the coolant outlet pipes, I didnt plug anything in it and its been fine.

Only main issues I saw were leaking vacuum pumps, valve cover gaskets, pcv leaks (whole valve cover assembly) and water pump sepage.

Okay, so I installed a new aftermarket pump in my MK4 Jetta 2.0 last year. Went with the seemingly highly recommended GRAF metal impeller pump that many forum members across multiple forums seemed to stand behind... 14K miles later and it's leaking. Anyway, after doing some more research, it seems that it's considerably more common for aftermarket metal impeller pumps (especially GRAF, but seemingly all of them from what I can find) to fail prematurely for some reason...

I just had my secondary water pump replaced a month ago. Yesterday I found a huge puddle of coolant in my driveway. Off to the VW dealer again. This time it's the water pump.

I've a 2012 GTI with just over 9K miles on it that had a water pump leak on me yesterday. Took to dealer and got it back this afternoon. I live 2 miles from the dealer and drove home no problem. On the way to my parents 40th wedding anniversary dinner this evening no more than another 2 miles after I left home it had another major leak happen. The coolant reservoir had completely cracked and I had coolant all over my engine compartment.

went in for my 20k maintenance/service on my 2011 GTI, Waterpump was shot, replaced free of charge but leaves me worried...
