Hmmm... Then why would Vince go to all the trouble to move the OE oil temp sensor, not once, but twice???
Remember, it used to be in the oil filter cap before it was moved to the oil cooler... There has to be more to the story. I'll bet that when you really need your cooler to work that 4 degrees will turn into 30 real quick.
BTW I got an IPR kit today. The under cover manifold seems to be pretty neat. The rest of the kit...? Not very impressed. The bypass valve is set for ~16.75 psi to bypass both the cooler and the filter. That's not going to work well when you're hauling the mail and the oil is bypassing the cooler... Except that the oil filter itself covers the bypass valve almost entirely... So no oil will bypass when it's good and cold when you really need it... But once the oil warms up and thins out, it will probably bypass like crazy at 16.75 PSI. And if you install the filter upside down on accident... No bypass hot or cold. We've been over the filter. That's going to be a severe issue as well. If you don't screw the IPR oil cap all the way down so that it sandwiches the oil filter between the cap and the base, you might as well not even have a filter. The whole thing is a catch 22...
The hoses look fine.
The 6.4 cooler is rated the same as the 6.0 cooler (I believe since it's the same dimensions).
The hose routing pretty much shows that Vince doesn't have a clue about thermal efficiency.
The fact that he still sells a kit where the coolant for the cooler comes from the HEATER hose should be enough to convince anybody something is wrong with this picture...
I like the coolant filter a little. The filter assembly itself is impressive. Who makes it? Does anybody know? The adapter is kinda clunky.
There is no way Vince's oil cooler bracket would last 20 min in Baja... That thing would be broken off and down by the A/C compressor or on top of the battery having it's way with either or both at the same time. Bye Bye vacation.
Is this kit something anyone should buy? ABSOLUTELY! We all need to learn things the hard way sometimes.
