Re: oil cooler/oil heat exchanger combo?

Brilliant, my man! I'm assuming that you're in agreement with my idea of
mounting it backwards, correct? I can explain it to myself and have it
make perfect sense. And then I can run it past myself again and prove that
it won't work at all. :^)

No worries, man. The check was sent out yesterday. :^)

-correct on all counts.

Actually, the european type is not a sandwich plate between the oil filter
mount and filter. The thermostat is actually *inside* the mount itself.
Therefore with the euromount and stock exchanger combined, were at the
stock length and appearance.

Correct.

Up to a point this is all good. In the beginning when just warming up,
it'll all happen more quickly. After that has occured, however, I don't
see the two systems working together most efficiently. The oil cooler will
simply assist the radiator in blowing off heat; that's all. Actually, I
guess that the number one question here is whether the perfect temperatures
for the oil and water are the same. If they are, then there is no need
for this combination. However, I'm figuring that there is a difference.
And as long as the two can be eventually separated, it is a good modification
for the car.

Nah, it is set and fixed.

It definitely can't cool too much. If anything the question is will it
cool enough. As long as the water can abe shut off from the exchanger when
it gets hot, it'll be gauranteed perfect.
