Thanks for the write-up, you saved me some serious coin. I have almost zero experience working on cars but I was able to pull this one off and change my belt at the same time (granted it took me a little longer than the time listed ).

Everything around the VR6 = bad
Im going to attempt this pretty soon, because my water pump is leaking pretty badly. Already ordered the new water pump.
Question: how "easy" does the water pump come out? Am I going to have to pry it out with elbow grease, or should it pull out fairly easy?
@24vGTiVR6, how did you use a bench vise to get it out?
it will come out easily... even the pulley will come off easily.. you might have to tap it a little to get it to come off the 1st time, but it does all come off easily..
I found it easy to lower the motor down and remove the lower 2 bolts and then raise it up as much as you can to access the upper bolt on the water pump itself..
all in all the 2nd time around I did my water pump in like 45 mins.. My 1st pump failed within like 3 months .. 1st time probably took me about an hour..
I am kind of curios as to what he is using a bench vice for now @ this point..... lol
I used the vice to hold the pump / pulley to get them separated, after the whole thing was removed from the car. If you have the 3 bolt pulley holder tool its a non issue, just loosen while holding the tool in place. I didn't have that at the time, so I took the whole thing out and used a vice to swap the pumps.
And my water pump (with the pulley) just slid right out, no effort at all really.
Just completed this and my thermostat/housing/crack pipe with very few issues! Solved all my cooling problems and running great! Only 1 pulley screw was a beast. Ended up dremeling a notch in it and using a flathead and hammer to break it free. Oh and one screw in thermostat housing snapped in the block below factory torque specs. I wasn't equipped to drill it so I just went with the two long bolts. No leaks, working great.
I've been following this DIY and I've gotten the bolts from the passenger side mount off. I've been trying to lift the engine up as suggested. However, I just can't seem to raise the engine as much as in this DIY. I don't know if I'm too scared to break something or if something is binding.
Is there no risk to damaging the driver side mount by pushing the engine up so much?
I also tried to drop the engine so I can get access to the water pump but the engine doesn't tend to drop as much.
What am I doing wrong here?
Good write-up. I kept easing the motor up small increments until I could get the pump out with the pulley off. I pried/pushed the motor as far forward as I could. I took the serp belt off and then stuck a long bolt into the wp pulley to break the bolts loose.
I'm "jetblast", but no one believed me when I said I moved and no longer had an old e-mail!
I noticed that a lot of people recommend replacing the OEM waterpump with a metal impeller version. From my personal experience, I went through 3 aftermarket waterpumps (metal impeller) within 3 years. The last one I installed only lasted 4 months before it started leaking. The leaks on all of them came from an internal gasket that allowed coolant to seep out of the housing itself, near the shaft of the pump. Finally I just bought an OEM one 6 months ago (expensive yes!), with the plastic impeller, and it's been holding up fine. My original waterpump lasted over 200,000kms as well, and when i removed it the impeller was 100% intact and solid. It failed because the seal against the block wore out. Just my two cents
Also, I'm not sure if anyone else experienced this, but I almost broke the screws that secure the pump to the block twice. I bought OEM replacement screws (x3) and when tightening them to the spec in the Bentley (I think its around 8NM), they just kept turning. I stopped obviously and removed them and they were stretched almost to the point of breaking in half. So either the Bentley is wrong or I got two bad batches of screws - the metal seemed to be super soft.
Either way, careful when you reinstall the screws! Because of this, I've used the original screws 4 times now...for some reason they tighten up fine.
