To replace the oil pan gasket on a 1990 Chevy Astro Van, first, lift the vehicle securely and drain the engine oil. Remove the oil pan by unbolting it from the engine block, taking care to clean the mating surfaces thoroughly. Install the new gasket, applying a suitable sealant if recommended, and then reattach the oil pan, ensuring all bolts are tightened to the manufacturer’s specifications. Finally, refill the engine with oil and check for leaks.
