Just like the title says, will the ls3 water pump fit a lq4/9 and work with the stock truck accesories?

 

It will fit. I *THINK* it will work

 

I'm pretty certain it won't. The pulley for the LS3 is not much wider than the belt, and its at the corvette acc depth. I don't think it works with the LS1 Camaro muchless the truck acc.

 

Look for the L99 Water pump. The crank pulley in the picture looks to me the "truck" pulley. It is spaced out further to clear the VVT solenoid. Part Number is 19207665. I still havent gotten around to checking mine for fitment.

 

GA95, you think you can check for me. I would hate to but the pump only to find out it will not fit.

Thank you.

 

I have one waiting on me for when I get back to VA. I'm in GA right now, so I will def let you know when I get back.

 

Thank you.

 

Ga any luck on checking fit/function?

 

Any updates on this?

 

the l99 pump will not fit with the truck alternator bracket. the outlet neck hits the bracket just under the idler pulley.
