Haynes lists the entire procedure for setting the position of the cams etc. Positioning of these is critical...If off by even a slight amount the valves WILL strike the pistons and destroy the engine. DO NOT use any parts made by SA Gear...They have no quality control and will deny any claim made against them. Make sure that the chain guides are in good condition and that the chain tensioner is operating properly.

On a 2.4, there are no timing marks...There are holes in the cam gears that need to be aligned with corresponding holes in the head.
Though it's not terribly difficult to do, it must be done precisely according to instructions or valves will hit the pistons and destroy the engine. You can find instructions for this procedure in haynes and other vehicle service manuals. (too long to write out here).
Remember...this is an exact install...you cannot just get close!!!
Good luck! Post back if you need further specific instructions with any part of the job.

YOU WILL SEE A HOLE IN THE CAM GEAR THAT A 3/8 BOLT WILL FIT INTO. PUT A BOLT INTO THE HOLES OF BOTH CAM GEARS. THEN LINE UP THE CRANK PULLEY KEYWAY AT ABOUT 12 O'CLOCK WITH THE MARK ON THE ENGINE BLOCK.
MAKE SURE TO COMPRESS THE CHAIN TENSIONER AND RELEASE IT WHEN THE CHAIN IS IN POSITION.

well, there a few ways to look at this. Yes it has a timing chain/belt. Most people replace them when they break, or if there is another reason to have work done in and around the timing cover, such as a gasket leak or, on your car, the hydraulic tensioner adjusted too tight from the factory.
After research, apparently these cars have had reported problems (ecotech 2.2 L4 motor.), but no help from GM.
Manufacturers suggest to change it at a certain interval/mileage, usually 60k.
