In my application the standard factory oil heat exchanger lowers my oil
operating temperature appx 15, 20 f at highway speed. (15/40 oil) That
cooler operating temperature (typically about 190f) also holds the oil
pressure around 60psi at 3200rpms....
After I swapped engine block to a 93 ABA Jetta 2.0 liter, I ran for a
couple of weeks without the factory cooler, the way the 1.8l Cabriolet
inline motor came from Vw, and I was seeing about 210f at speed. A major
highway climb at speed was causing the oil to hit 230f, and at that
temperature, the operative oil pressure did not please me. I re-used the
ABA cooler from the donor motor. Now, the oil temperature stays good, but
INTERNET rap says the factory coolers often fail..and the rap was right, I
think.
At least now I have an excuse to replace the coolant hoses now. I
have run a few hundred miles with the coolant lines to the factory cooler
connected... Nothing bad happens, other than less cooling, that I could see.
Finding hoses to route coolant to the 1.8l head (and the cooler) I have
on my hybrid inline, that required some creative routing...
