Running hot.. Can't figure out why.. Please help.

When is it overheating? Idle? During cruise? Got a vacuum leak someplace?

Tell us about this high performance water pump. The "heavy duty" pumps that a lot of auto parts joints sell actually cool less well (have fewer blades) than a standard pump! This is because there were different pulleys (and thus different pump rpms) based on which accessories you had.

How many CFM is this electric fan?

Got a pic of your water pump pulley?
