Never one to leave things alone, and in my search for the best oil cooling
for my TD, I have arrived at a new idea: Use the stock TD water-cooled oil
cooler, but instead of utilizing the already-hot coolant of the engine's
cooling system to try to control oil temps, build a secondary cooling system
dedicated to only the oil cooler. Install a small radiator in front of or
below the current factory unit (van has no AC), and use a small pump to flow
the coolant to and fro. I'll also add a temp switch to signal the pump to
operate only when oil temps exceed the desired amount. I figure this should
be a lot less strain on the oil system than running an air cooled oil cooler
up front, with 30 feet of hose. (My recent rear-mounted air cooled unit did
not control the temps in the high mt. passes of the west, neither did the
stock cooler) The only part I haven't found is a small coolant pump that
could be run constantly at 200 or so degree temps. I had thought of using
the ($$$) Audi aftercool pump from the turbo models, but that isn't really
designed to run more than a few minutes at a time. Any ideas or comments?
Thanks.
