Follow these steps carefully
Disconnect the negative battery cable. Drain coolant and oil if the front cover must come off. This is an advanced job — have the service manual torque/timing specs ready.
Remove the serpentine belt, harmonic balancer/crank pulley, and any brackets blocking the timing cover. Support the engine if a mount must be removed. Unbolt the timing cover carefully and note sealant locations.
Rotate to TDC and install cam/crank locking tools if specified. Relieve tensioner pressure, remove the chain, guides, and tensioner as a set. Inspect sprocket teeth for hooking or wear and replace sprockets if worn.
I've learned to lock it at TDC and do not trust your memory of the marks — on this engine a tooth off means doing the whole front cover again. Rotate it twice by hand and recheck before the cover goes back on.
Fit new guides and tensioner, then route the new chain with colored links or marks aligned to the sprocket marks per the procedure for this engine. Oil the tensioner as required before activation.
Activate the tensioner, remove locks, and rotate the engine by hand two full turns — reconfirm all marks. Clean cover mating surfaces and apply the specified sealant bead; install a new front crank seal. Torque cover bolts in sequence.
Clean the cover mating surfaces completely and lay the sealant bead exactly as specified — I have seen more timing-cover oil leaks from rushed sealant than from bad gaskets. New front crank seal while you are in there.
Reinstall the balancer, belt, and mounts. Refill oil and coolant, reconnect the battery, and start the engine. Listen for chain rattle on cold start and watch for oil/coolant leaks at the cover. Clear cam/crank correlation codes and verify with a road test.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
