N14 oil cooler

I was servicing the n14 in the 01 Pete i bought a couple months ago, went to change the coolant filter and it appears that the internals must be plugged, there was only about an ounce of coolant in the filter and the underside of the spin on housing was dry. So, tomorrows project is gonna be pulling the entire cooler assembly to clean it out/inspect it, thought this would be a good time to change the oil cooler as preventative maintenance to avoid downtime. Called cummins, they want $1100 CDN for just the cooler, thought that was a little steep so i searched the net, seems everyone is selling a cooler PAI industries, looks identical to the cummins unit, i like genuine cummins parts but thinking this way more reasonable option at a 3rd of the price for a cooler that looks the same, and probably is the same one cummins sells and jacks the price. Any input on this guy? Has anyone ever used PAI's products?

 

It was closed when I took the filter off, but even with it now open it is still dry

 

took the housing off of the motor, and since the valve has been closed for who knows how long, it is all plugged up inside. Does anyone know how to remove the valve from its seat? It appears that once that Allen bolt is out the valve should just pull out with a decent grunt from a prybar, the good news is the oil cooler is bright and shiny inside.

 

got it pulled with a wrench and prybar, i can see why there was no flow, i had actually had to chisel the crap out of the coolant holes. Gotta wait till monday for some gaskets and o rings now.

 

I use turbo power heavy duty antifreeze, it's pre charged with sca's
