So I've read of some people Prophylactic changing the water pump on these 5.0 coyote engines due to occasional failure of the plastic impellers. I'm getting close to 140k on my stock so thinking it might be a good idea- or does it even matter? Looks like 99% of the aftermarket units as well as the ford replacements still use plastic impellers with the exception of AC Delco...
Along that same line, some people advocate changing the belt tensioner and idler pulley but again this is something I've never done until failure. Thoughts?
