Radiator & Trans Cooling Lines - what's this?

<< < (2/2)

roadking77:
I asked an Olds friend of mine. He is pretty sure the outlets on the motor side are for oil cooling which would have been a rare option on the car. They should be a bit larger than the outlets on the front side which are for transmission cooling. I suppose if you are not using the oil cool function you could plug those two?

I had a diesel Toronado and it had a set of coil cooler lines like that.  So I'd say that's an olds diesel rad out of 40-year-old something or other.

You don't have to plug them if you don't use them.

Wallington:
Are the front lines larger than the rear lines, or look to be the same? Have read those that used the engine oil coolers on the diesels used a larger line, perhaps 1/2", due to the thicker consistency than trans fluid.

Wallington:
One would hook up to this:

Mine was that way if I remember correctly.  1979 Toronado.  It's been 40 years, so I could be wrong.
