Timing CHAIN
To change the timing belt on a 2003 Mitsubishi Lancer, first disconnect the battery and remove the accessory belts. Next, drain the coolant and remove the radiator for better access. Align the timing marks on the crankshaft and camshaft, then remove the old timing belt, tensioner, and idler pulleys. Install the new timing belt, ensuring proper tension, reassemble the components, refill the coolant, and reconnect the battery.
