11 Feb,

My SRT6 water pump was just replaced with the MB 1122001301 with no problems, that is if you don't consider a hefty chunk of change a problem. An aftermarket pump couldn't be found that would fit.

If you want to change your serphantine belt and can't find an aftermarket one, the MB belt is 112-997-00-92.

Both MB parts were less expensive and in stock compared to the Chrysler ones.

If you've swapped out any pulleys be sure to also replace the water pump idler pulley bearing with an upgraded one. I believe either Needswings or Eurocharge has the bearings. Hopefully a forum member can provide specifics.
