The bolt pattern looks the sameI got this welded non slip one from sinister diesel. It says it fits all 06-16 . Does it matter if it is 8 blade instead of 7? I called gm and they said there is only 1 pump for 2006 so it shouldn't matter if it is lly or lbz. Are all of these places selling them online listing the wrong year?
I didn't think 06-16 pumps fit on 01-05 because of different bolt patternI personally haven't seen a later generation pump with a cast metal impeller. All the one's I've ordered have been plastic. The cast impellers are prone to slipping on the shaft and causing an overheat condition with high rpm which is why now most guys run the 06-16 pump in 01-05 trucks as well.
You're correct, hence why DHD drills them for the single different bolt location and modifies the front covers. Then it's as easy as drilling a hole in a new water pump should yours fail as you already have the cover.I didn't think 06-16 pumps fit on 01-05 because of different bolt pattern
