2 hour oil cooler install, Preparations for WCC Options

[Demick]

I finally got around to installing my aux oil cooler. Used a Mocal thermostatic sandwich plate and Derale fan/cooler. Aeroquip blue hose with -8AN push on ends connected it up. Hose runs next to valve cover and zip ties to the wire bales (should make valve adjustments interesting). I removed the heater J tube on the passenger side to route the cooler lines. Since that J tube was just capped anyway, I just removed the J tube and put the cap where the J tube normall attaches to the heat exchangers. So there is no change to the heating system.

Andy - you are right - the lines run under the stock cooler. But that is the only place to run them with a sandwich adapter. Still, the air exhausting the cooler is still cooler than the oil temp in the hoses. So it cannot further heat the oil.

The air going through the aux cooler is not ambient, but it isn't 200F either. If I am stopped at a stoplight, it probably gets pretty hot under there - but I don't need extra cooling when I'm stopped. I need it when I'm going down the freeway at 90mph or whatever. At higher speeds, there is lots of turbulence and fresh air gets mixed with exhaust air etc.

Here's an example. Drive down the freeway on a warm day. Now pull over and open the rear trunk and feel how warm the floor of the trunk is. Is it warm? Yes. Is it 200F? Nope. Maybe 120 or 130F. The air under the trunk is pretty much the same temperature as the floor of the trunk. So that air is still about 100F cooler than the oil. Should be able to do an adequate job of cooling.

Is it good enough for a 20 minute session at Thunderhill on a 105 degree day? Nope. But I didn't intend it for that.

Aaron: The sandwich adapter was about $90. The price per foot of hose was just over $3. But the real savings on this type of hose is the fittings. The 90 degree elbows were $7 each as opposed to nearly $20 each if I had used the traditional Aeroquip reusable hose ends.
