Tools Required: Socket set, torque wrench, timing chain tool kit, oil catch pan, OBD-II scanner.
Disconnect the negative terminal of the battery.
Drain the engine oil into an oil catch pan.
Remove the engine cover and any components obstructing access to the timing chain (e.g., air intake, accessories).

2. Remove Timing Chain Cover

Remove the bolts securing the timing chain cover using a socket wrench.
Gently pry off the timing chain cover, taking care not to damage the gasket.

3. Remove Old Timing Chain

Align the timing marks on the crankshaft and camshaft gears as per the service manual.
Remove the tensioner and guide rails from the timing chain using the appropriate socket.
Carefully remove the old timing chain from the sprockets.

4. Install New Timing Chain

Place the new timing chain onto the crankshaft and camshaft sprockets, ensuring the timing marks remain aligned.
Reinstall the timing chain tensioner and guide rails, following the manufacturer's instructions for torque specifications.

5. Reassemble and Refill

Clean the timing chain cover mating surface and apply a new gasket or sealant as recommended.
Reinstall the timing chain cover and torque the bolts to the specifications.
Refill the engine with new oil and reconnect the negative battery terminal.
