This engine model, the B254, didn't feature an oil cooler as standard equipment.
However, it's worth noting that:
* Some later models of the 9-3 (2003-2011) with the B235R (turbocharged 2.0L) and B207R (turbocharged 2.0L) engines did include an oil cooler as part of their design.
* Some owners of the 1996 Saab 900 2.5lr V6 might have added an aftermarket oil cooler, particularly if they are doing heavy-duty driving or modifying the engine.
Therefore, to be completely sure, you should check the specific vehicle's documentation or inspect the engine bay. Look for signs of an oil cooler, such as a small, separate radiator-like unit connected to the oil lines.
