As I get opportunity, I intend to refine this page.



The whole purpose of this page, is to reveal the procedure of replacing the inferior stock oil cooler, with a remote oil cooler, that works really well. The new oil cooler (that resembles a heater core, which I suppose could be used instead), with a cooling fan (which I trust could also be replaced with one of a proper size out of a junkyard as well), were purchased together as a kit, that EMPI sells. I bought this kit about 15 years ago for my '74 bus, and never found the time to install it on that bus. Years later, here we go...

Here is the rear of the engine, with the belt, pulleys, left intake tubes (including the left side fuel injectors), the distributor, the left upper cooling air shroud, the thermostat cable, and half of the fan housing removed (did I forget to mention anything?). The remainder of the fan housing must be removed as well, to gain access to the oil cooler.



Here is a bird's eye view, showing the attached stock oil cooler (on the left).



And here is another view from the rear, of the oil cooler still attached.



Here you can see where the oil cooler used to be attached.



This shows an adapter attached, which reroutes the oil to and from the remotely mounted new oil cooler. It was also part of the kit, along with the hoses, and fittings, etc., which can also be bought separately (be sure to use new oil seals!).
The fittings need to be really tight, but very carefully installed, so as not to break the adapter.



Here are the hoses attached (just connect each end of the one long hose to each fitting, until you are ready to cut the hose in two). I had to trim the mounted bracket that you see, to make way for the hoses (be sure no sharp edges will be able to cut into the hoses).
Also, you will want to position the hose clamps to be able to be tightened from below (specially made high pressure hoses which I am considering, are the ultimate, to prevent leaks).



Another Bird's eye view.



Below, is the piece of cut, and formed tin, that will slip into the bracket shown above, so as to cover the breezeway that the old oil cooler used to use.
I happened to have an ample supply of old license plates to choose my material from. From this, you can probably guess which state I live in.



And here is that piece of tin installed.



As you can see, I have also remounted the fan housing.
Now you can see the flapper installed over that chunk of tin. Be sure the flappers work freely!



Make certain the thermostat is properly reconnected. When done with all else, it is vital, that you check that the thermostat and flappers are operating properly!



Now for a worm's eye view.



Make sure, that the hoses will not be getting cut by anything along the way!



Here I have draped a chunk of scrap sheet rubber (from the old floormat out of the cab),over the hoses to protect them from any sharp edges.



You will have to trim a slot in the appropriate engine shroud tin, to make way for the hoses back up into the engine compartment (You can cut a slit along the length of another similar sized rubber hose, to cover the sharp edges of tin that are exposed).



Here is the fan, mounted to the cooler, with all the hardware assembled (and brackets fashioned as you desire).
I had to drill holes through the plastic housing, for the 10/32 bolts that I needed as well.



Here is a view of what will be the bottom of the cooler/fan assembly.



This is the coolers new home. This is the place just in front of the left rear tail light assembly. Note the installed 1/4" X 1" bolts, and nuts installed in the base, that the left side brackets will slip over (through the holes in each bracket).



Next I installed sheet metal screws into the feet of the mounting brackets on it's right (passenger) side.
I don't bother renutting the left side bolts, as they are stable enough without (as well as being too hard to get to).



Here you can see, that I eventually installed a couple brass tees into the supply side of the cooler. This manifold, provides a place to mount an oil temperature sensor, for a gauge in the cab, and a future home for an oil pressure sensor as well (don't mind all the scattered wires, that will get bundled up later).



This view, shows how I remounted the heater blower.



And this view, shows some assembled PVC pipe, that helps direct warmer air from the cooler, into the remounted heater blower.
