I got my new OEM cooler line in so I was ready to start making changes. But just to make sure things
would go as expected, I spliced into the cooler circuit with some 1/2 inch polished SS tubing. I started
the engine and watched for 4-5 minutes and nothing went wrong, but then I turned my back and went
to the front bench in the garage. That's when I started smelling something hot, when I turned around
the line had pushed it's self of the tubing I used for the splice. By the time I shut the engine off it had
pushed out just over 2 quarts of fluid. I did have a pan under the Nav that caught most of the fluid, but
about 1 cup was on the ground.
So I replaced the SS tubing with some aluminum tubing which I roughed up with some emery cloth
before installing. This seemed to hold for 20 minutes with no problems. I then went for a 30 mile
highway cruise and it was working with no unexpected consequences.
While watching the setup before leaving on the 30 mile cruise, I measured both input/output lines to
the OEM cooler. There was a consistent 15°F difference across the cooler with the hottest line going
across the the bottom of the cooler in the photo below. I did have a floor fan blowing across the cooler
to help make a greater difference between the input and output lines.
To make sure I didn't have the same problem as above with the line coming off, I slightly flared the
end of the steel line I cut thru. It was still easy to push the new hose from NAPA that I bought.
So I can now confirm that I have configured the system with the OEM cooler first, then it
goes to my remote filter and Derale remote cooler, like shown below. [Filter not shown]
It's the same photo as above, but this is my final configuration. So far all I can tell is the fluid temp heats
up slower, but with the weather cooling off, it's going to be nearly impossible to do a good comparison. Guess
it will be next year, so much for a scientific study.
