Pulley type on water pump matters?

[sidespyder]

Hi

I ordered a new water pump for my 2008 VE SS L98 here:

https://www.holmart.com.au/holden-commodore-vt-vx-vu-v2-wh-vy-wk-vz-wl-ve-wm~10418

I've just noticed the pulley on my current water pump is flat where as the new one is dome shaped, looks like there is plenty of clearance... anyone done a genuine GM water pump on the VE SS and noticed this?

that looks almost identical to the one I got for my LS1 (in a VXII) a few years back. The one that came off and went on both had the dome look.

I would say your old one is aftermarket.

As long as the belt lines up it will work.

id be checking the back of it for clearance of timing cover as ls1 ( which this looks like )will bolt up if the bolts are ground down/replaced with a flat head

Yea the back looks like the picture in the holmart link, I think its OK.

its an LS1 pump same as i have on Maloo, not L98 one i used on my VE SS, had flat pulley, you can do it the other way for clearance

there is also a difference in the pumps on later models, the top hose connection is on the other side of the pulley (it is concaved pulley the same)
just went through all this as i changed my pump only 2 months ago, was concerned with pulley position please keep us informed as i wanted a genuine but none were available in Aus and had to use aftermarket

yep, mod the same as in clip or use countersunk bolts. also the edelbrock pump will bolt up if you want something heavy duty

back of mine looks like this

So guessing grinding bolts isnt relevant, just seems they dropped the flat pulley for the dome type

it drops down development costs, tooling etc if they only have to make 1 type thats multiuse rather than several different types.
