Come on out! Actually I'm in the Dominican Republic today. Really good coffee down here. Come on down! ☕️

Ok, that makes sense. Will you tap the oil pan?

That's the plan. There actually a plug in the side of the pan that can be used.

I had a bit of an adventure on my last road trip...the AC compressor came loose and the fan hit it busting up a couple things. I was able to straighten things out and patch them back together and get back on the road.
I'm now home and trying to do a proper job putting it back together. I found an original replacement fan for over $800. I also found a modern replacement fan with all the same specs but it's composite and has one more blade so it should push more air for $125 made by ACS part number 444100-24. Not sure if it will pull more horsepower, but it should be much lighter so less rotating mass etc.
I also spoke to one of the old timers at Spartan. He said make sure no air that ran through the CAC could get sucked back into the motor bay- make sure there is a good seal around the radiator. I had a look at mine, and it looks like there was some kind of shroud or material that was removed so I do have a space all around my radiator. I'm hoping one of you fellow pusher guys can tell me what I'm missing and post a photo?Click image for larger version

Overheating!

Check out my Killer Dowel Pin thread. Post #9. When I removed the unused oil cooler on the 95, I cut the core out and used the frame to support and seal the space between the CAC and radiator. The thread also shows the baffling around the radiator. It's just that aluminized rubber mat.

My 94 pictured in this thread had the cooler removed and they didn't use the frame or seal the gaps.

Charge Air Cooler. Fancy way of saying condenser for A/C.

Charge air cooler is correct. But it cools the compressed air off the turbo charger before it enters the intake manifold. Commonly called an intercooler in the automotive world. Diesel truck parts sources generally call them charge air coolers.

At 30 lbs of boost the air off the turbo gets surprisingly hot. Not uncommon to see 250 degrees. The CAC pulls a lot of that heat out increasing the density of the air pumped into the cylinders. It's a significant performance gain.

Ok, now I understand. I was thinking the discussion was just about the A/C system. But even so I had never heard the term CAC before so thanks for the clarification!

The dash A/C condenser on these rear engine Classic 360s is up in the front with an electric fan.

Foot in mouth disease. I wasn't thinking diesel or rear pusher at all. Charge air as in compressed air charge. (Bowing)

New fan installed, AC compressor and belts back in, and everything working well with locktite and lock washers on everything. The new fan is about half the weight. It's a pain to install from the front, but possible. The AC compressor and the bracket the fan is attached to need to come off. Probably easier to take the CAC and radiator off...

ID:	247600the bed and could do me a favor- I would love to know how much room there is between the tip of the fan blade and the AC compressor. Mine is a close fit, and I'm a bit concerned that the fan could flex and hit it again. Kind of makes me wonder if the mechanic put the old fan on backwards and that's what caused the whole problem.

I can check tomorrow. An electric fan clutch would space it further aft and maybe improve efficiency.
