Water Pump Replacement 5.7
About 1/2 mile from home I smelled coolant. After some trouble shooting I confirmed that the water pump failed (45,000 miles). I am considering replacement pumps and would appreciate some input. The standard Mopar 68346915AA says that it is for "without oil cooler." I added an oil cooler 6,000 miles ago as part of my build. Could this have caused the pump to fail? Regardless, anyone know if the SRT water pump (for with an oil cooler) will fit my RT, and if it is the right water pump to get? what's the difference?
I could also go aftermarket at the local O'Reilly's. There are (2) Murray water pumps that will fit. One has a plastic impeller, and one has a metal impeller (but is "from 3/4/2013" - my car was manufactured in 2012). Not sure why there are different part for the same model year but with different build dates. Anyone have any thoughts on this?
