Several members have asked in the past for a Jeep CRD coolant hose connection diagram.
I searched extensively on the internet and to the best of my knowledge, one simply does not exist currently!

So, I have developed one the with help and feedback of a couple of very knowledgeable fellow LOST members.
Many thanks to GordnadoCRD and Turbo-diesel-freak for their help and input on this drawing!

Please NOTE: EGR Cooler is not shown on this diagram!

oh great ...the oil cooler has coolant flowing thru it to cool the oil?

can we remove the oil cooler and block off the mounting area with a plate and gasket? and run a PROPER huge tube and plate oil cooler with a fan?

You already can.

Without inviting leaks and reducing cooling capacity.

The factory oil cooler is actually part of the oil flow path from the sump. You cant just remove it and block it off. You need something in its place to complete the circuit.
On european 2.5L engines, this is where the oil filter was.

I dont think there is anything wrong with the factory oil cooler.
Given its placement in the cooling system, it should keep engine oil at the same temperature as the coolant, maybe even a few degrees cooler.
Of course, without a oil temperature gauge, we will never know.

I agree!
The oil is being cooled by the coolant right after it leaves the water pump so the oil will be cooled to within a few degrees of whatever the water pump suction / radiator outlet temperature is.
I would be very curious as to what the temperature of the water pump suction/radiator outlet temperature is.
We know the coolant entering the radiator is maintained at ~180 degrees by the OEM thermostat.
Knowing the outlet temperature of radiator would tell us the differential cooling efficiency of the radiator...

so basically a spin on filter adapator (like the DeRale kit linked below) can be threaded onto the space where the factory oil cooler is?

Yes
Spins on just like an oil filter. If you get it slightly tighter than you would an oil filter, then you can spin the oil filters on and off without breaking the adapter loose. Doesn't hurt anything if it does, just makes one extra step to change filters. Or just wedge wood, rubber, or something along side to keep it from coming loose.

No.
If you want to remove the factory oil cooler, you must replace it with something that fits the holes in the side of the block. The factory oil cooler is part of the oil flow path.

Just curious, why would you want to remove the factory oil cooler? I have not heard or read of any problems or issues with the OEM cooler.... :shock: :roll:

Woops! Sorry, Flash is correct. I mis-read the question. the Derale system spins on between the oil filter and present filter mounting. Not the factory cooler.

Edit,
Added EGR junk and flows to original drawing and developed a stand alone EGR drawing.
