This is relevant to the 6 cylinder 9-5 only. This has no relevance to 4 cylinder Saabs.

When my oil cooler began leaking coolant, I began investigating alternatives to the USD $460.00 Saab replacement oil cooler. I'd read on the Saabnet Forums that the Cadillac (97-01 Catera and 03-04 CTS) and Saab (~2000 9-5 SE 6 cylinder) use the same basic engine. In an attempt to save some cash, I decided to order up an oil cooler for a Cadillac to see if it would work. The Cadillac part was USD $230.00. I ended up returning the Cadillac oil cooler (part number 93176626) and purchasing the proper Saab oil cooler (part number 4770988).
