Have a 2008 short bed 4x4 w auto and 3.0 motor. Took a rock in the radiator and will probably have to replace it. I like to swap things up when ever possible and i think the standard 99 year 5.0 Explorer radiator with its 2-3/16 core may fit any body done this out there? Does anyone know if it will fit? I think i have enough space for the fan and hopefully i can use the factory shroud?

On a slightly different note. I understand that the 3.0 has an issue with gasket failure on one of the timing cover water ports. Form my industrial experience this could be caused by water velocity that is too fast. it seems like there is plenty of gasket surface there. I was thinking of running an undersized pully on the water pump. I dont want an undersized crank pully and dont want to slow down my alternator, AC or power steering. I can monitor the temps from the gage and am thinking of finding a junkyard pully i could modify to slow it down a little bit. Should be easy enough to do i dont mind a little bit of extra power along with other small things i might do it could contribute to an add and i doubt the water volume will suffer. Pumps in such situations can cause cavitation a destructive situation where the velocity especially where there can be odd bends in the water flow etc. It seems to me that the engine was originally designed for transverse mount and rerouting the water flow for standard mount may be part of the issue. I'm just pondering this now not sure if i will do it but am seriously thinking on the 5.0 radiator.

 

a smaller pulley on the water pump will make it spin faster.

A smaller crank pulley slows everything else down, it acts like all the other pulleys are bigger.

So to slow the water pump down without affecting everything else, you need to make the water pump pulley bigger.

 

You are right. I was thinking that later that night. might also be easier to find a bigger pully too. Thanks for the double check though.
