Yeah - technically they are both OEM brands so you could get either from the dealer depending on what they got in stock there but I hear more folks talking about the Graf pumps vs. Meyle. I'm trying to do this economically but if one is better than the other for a few bucks no biggie.

Well I ordered $425 worth of parts and it should all be here this Thursday.

This is a really good post too with respect to making a pulley tool. I also found another link in that post that explains this wd-40 + screwdriver trick with pictures. I think I will give that a shot first since it's much cheaper to do lol.

Someone also mentioned using some 10mm sockets or wrenches to hold the pulley in place. Now all I need is a thin 32mm or 1-1/4" box wrench.

OK - got all my stuff today. If you order from AutoHausAZ - you do not need to order the o-rings and gaskets separately as they come with the WP and thermostat. I am going to send my extras back I guess.

I should be cracking into this job this weekend.

Sending them back might not be worth the trouble and expense. Maybe someone here will read this thread and just buy them from you instead :)

Yeah - seriously i think its maybe $5 altogether. One thing I hate about ordering parts online. I have a brake wear sensor cable that doesn't fit my vehicle also that I somehow mistakenly ordered in the past. At least at a dealer you see what you are getting there and it's easy to return stuff you don't need.

Thing that pisses me off is that their website tells you that you need these items too - but then you end up not needing them b/c they are included.

On the gasket for the wate rpump - does it just go straight on the clean surface or should one apply a thin layer of RTV silicon gasket maker to each side??

I just returned from the local "Stealer". I had the same symptoms. Diagnosis: Water pump is leaking & Expansion Tank is leaking. Mine is a 2000 w/ 4.4i & aparently I am about due for this at 106K mi. Repair cost =$650.00. Also, most coolant hoses will need to be replaced and don't be surprised if the radiator starts to go south around 120K. R&R for the water pump is rather extensive but a guy w/ a full compleemnt of metric tools can do it.
Good luck to you.

Hey we350z, if you really feel liek getting rid of the gaskets you could always throw them up on Craigslist or just be a nice guy and give them to a local indy/stealership so at least someone can get some use out of them. I always feel a little bad in the back of my head when I waist or throw away perfectly good parts when someone else might be paying for something I have just sitting around.As for the gasket install, a little sealant won't hurt to assist in holding it in place. I've seen people do little dambs in each corner, but for me its all or nothing...no sealant or just run a thin bead around one side of the whole gasket to assist it from moving around while your shoving your hands in a mildly tight area.

ok - what about for the coolant pipe o-rings? I see they are pre-loaded into the water pump. Is it a good idea to put some coolant on it for lubrication so it will slide easy and not roll the rings? Engine/oil or vaseline?

With o-rings I usually use whatever fluid it is used for, in this case coolant. But it wouldn't be horrible to use a thin smear of vasoline on the o-ring/pipe. Just don't glob on anything and you'll be ok.
