Is the belt spacing the same? I thought there was a minor difference in the outlet of the pump but cant seem to find the specifics. Trying to decide what pump to get, putting an LS3 into my 03 with efans.

 

03+ water pumps have a new thermo housing. Just use the pump for your truck and you'll be fine.

 

Is the belt spacing the same between a 2003 and 2009 truck? I am putting an L92 into my truck using my (2003) accessories and would like to use the L92 water pump if the belt spacing and everything is the same.
Thanks

 

Yes that should be fine
