A long time ago, in a garage far, far away, a grimy parts monkey sold me this radiator and oil cooler combo for some ridiculous price. I bought it on the spot and was d@mn happy about it. I was told it was 'the wagon size oil cooler' and thats why it was so expensive.

Today I bought the larger of the two oil coolers @ the JY, it measures just under 4" in width and I took it from a turbo model. The one in my car measures just under 3" in width and I have no idea what its origin is.

Where is this smaller oil cooler from?

What is the likelihood that my high operating temps are the cause of this small oil cooler? - - I easily reach 100*C on a good 1/4 mile uphill climb in 80*F weather, but it stays right there.

Who has some good suggestions for cleaning an oil cooler, or should a shop do it?
