To replace the oil pan gasket on a 2003 GMC Safari van, first, ensure the vehicle is on a level surface and securely raise it using jack stands. Drain the engine oil and remove the oil pan by unbolting it from the engine block, taking care to remove any old gasket material. Clean the mating surfaces thoroughly, install the new gasket (or apply gasket maker if required), and reattach the oil pan with the bolts tightened to the manufacturer's specifications. Finally, refill the engine with oil and check for leaks.
