BEST ROCKAUTO WATER PUMP FOR A 5.7 HEMI?

Any name brand part should work well enough. Just be honest with yourself before ordering anything; did it overheat badly or just run a little warm while it was leaking. These engines will often drop a valve seat shortly after replacing a water pump IF it was badly overheated. If it boils over a lot or several times, be prepared for the worst.

I knew about this and tried to keep it from overheating when my 2008 started leaking coolant about a year and a half ago. So far it is still running, so I think I am ok.

Also check the fan clutch for excessive looseness. Mine was wobbly, not spinning loose. I figured that contributed to the water pump going out. Plus, here in Michigan with salted roads in winter, the fan blade rusted badly and was delaminating. The blades were coming apart like sheets of paper pealing off. So, check all that before ordering parts. Hopefully yours is ok like mine was.
