However, "interchangeability" is a complex issue. While the engine might *bolt in*, you'll need to consider:
* Specific Engine Code: The exact engine code (found on the engine block itself) is crucial. Slight variations between years and even within the same year can exist.
* Wiring Harness and Computer (ECM): These need to be compatible. A simple swap isn't guaranteed. You might need to adapt the wiring harness or even replace the ECM.
* Exhaust System: The exhaust might need adjustments or replacement.
* Transmission Compatibility: Make sure the transmission is compatible with the replacement engine.
* Mounting Brackets: While generally similar, minor differences might require some adjustment.
It's strongly recommended to consult a Saturn repair manual or a reputable parts supplier (like a salvage yard specializing in Saturns) to confirm exact compatibility. Simply looking at the year is insufficient. You need the precise engine code for a reliable determination.
