Where is the starter located on a 1997 Cadillac sts Seville?

On a 1997 Cadillac Seville STS, the starter is located on the passenger side of the engine, towards the rear (firewall) side. You'll likely need to remove some components to access it fully, possibly including parts of the exhaust system or some heat shielding. Because of its location and the surrounding components, it's a relatively difficult starter to replace compared to some other vehicles.
