2001 Cadillac Seville • V8 2WD Automatic • 144,000 miles

I have a 2001 cadillac seville sts and I have to replace my radiator due to a leak that is now causing the car to overheat. How do I know if I should get a radiator with engine oil cooling or not?

I don't believe either model in 2001 had engine oil cooling. The earlier Sevilles(-97) did. The way you can validate this is to check on the passengers side of the radiator for lines attaching to the side tank. If there are none, it has no engine oil cooling. The transmission oil cooler is the one on the left(drivers) side of the radiator. Typically, on earlier years, it was the higher power option(engine code 9) that had oil cooling. Models like the Eldo ETC, STS, and Deville Concours.
