Replacing water pump on 2000 f450 7.3L diesel. I have pump in hand, new airtex from northern auto parts.
1) Should put new thermostat in while i'm in there? What brand and temperature range?
Heavy bucket truck hauling heavy equiptment and sits idiling long periods of time while working boom that runs off pump from engine.

2) Is there water pump replacement link somewhere on site?
Have seen repair videos on you tube before, lost that link, hopefully
someone can direct me to it.
Thanks in advance folks, the people on this site are always so helpful.
