Do you need to remove the crank pulley change oil pan gasket on a 1995 Chevy Lumina 3.1 auto 4dr?
No, you generally do *not* need to remove the crankshaft pulley to change the oil pan gasket on a 1995 Chevy Lumina 3.1L. The oil pan is located below the engine, and access is typically achieved from underneath the vehicle. While some other components might need to be removed (like the oil drain plug and possibly some heat shields), the crankshaft pulley is not in the way.
