Here is a brand new dealer purchased AC Delco Water Pump for the high performing 4.6 Northstar V8 as used in the 2004 and 2005 Bonneville GXP.
Pump is offered under a few part numbers but I will give you PN # 251660 which I believe is the latest one in use. Regardless the pump fits 1995 to 2005 Northstar engines both 4.6 and 4.0 litre versions. This means that beside the Pontiac Bonneville it will fit Seville, STS, Eldorado, ETC, Deville and DTS plus the Aurora.
NOTE: it will not work on early 93/94 versions or the last 2006-2011 version.
Our friends at Rock Auto sell this for $77 while your friendly GM dealer asks over $300. If you have one of the cars listed above and you have not changed the water pump you are now just playing Russian Roulette, its only a matter of time until the pump seizes and ruins your pulley, tensioner and belt and a $1,000 repair.
Get some insurance now and change it. This version is easy to do but does need special GM tool to rotate the pump out of its housing. I don't have a Northstar in the vintage listed anymore so here's an opportunity for a real bargain.
$70 plus shipping, gasket and instructions are included.
OVER $300??? WOW! You guys in Ontario have some major thievery going on there... At my local GM dealer, full bore list is $177.77... Granted, over 2wice of Rock Auto plus whatever shipping is involve but WOW! Just wow....

Well the dealer quotes at $292.15 so add in 13% and you top $300.
I got my latest one for my '06 from my Parts Guy for $175.29.
