To replace the timing chain on a 1994 GMC 2500 Vandura, first disconnect the battery and remove the front engine covers. Align the timing marks on the crankshaft and camshaft gears to ensure proper timing. Remove the old timing chain and gears, then install the new chain and gears, ensuring the timing marks are correctly aligned. Finally, reassemble the engine components, double-checking that everything is secure before reconnecting the battery.
