Chrysler Sebring Timing Belt Replacing Procedure how do you properly set and align the timing marks on the 2.4L DOHC motor. I've tried it with the Haynes manual several times and keep getting a stumbling idle with an occasional shut down after racing the motor and a engine code P0016. I set the crank gear one tooth before the mark, the intake cam just like it it suppose to be, and the exhaust cam about half tooth back. Starting from the crank, up to the intake, then to the exhaust cam, using a wrench to turn exhaust cam to line up with intake, and use the tensioner to take up the slack and turn crank to line up. I have done the timing belt on the 2.4 engine like that since it came out. INSTALLATION -  TIMING BELT Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing. Set camshafts timing marks so that the exhaust camshaft sprocket is a 1/2 notch below the intake camshaft sprocket. CAUTION:   Ensure that the arrows on both c...

When To Replace Timing Belt Timing belts have replaced timing chains on many of today's engines. Not to be confused with “V-belts” or “Serpentine belts”, which are located on the outside of the motor to drive accessories, timing belts perform a much more vital role. The purpose of a timing belt is to provide a connection between the camshaft and crankshaft to ensure that the pistons and valves operate together in proper sequence. Timing belts have proven to be lighter, quieter and more efficient than chains, but those benefits come at a cost - they require more frequent replacement than chains. Timing belts are used in two types of engines designated as "free-running" and "interference". If the timing belt breaks on a “free-running” design, the engine will stop and you will need a tow to the repair shop. There is enough clearance between the pistons and valves so no mechanical damage usually occurs. The installation of a new belt is usually all that is neede...

TIMING BELT Working Of Timing Belt Helpful Information Timing belts are more common in overhead cam engines and are more easily serviced than a timing chain. A timing belt is constructed of a fiber reinforced rubber with vertical ribs vulcanized to the inside of the belt. When a timing belt fails it will allow the ribs to shred stopping the driving motion. To check the condition of the timing belt (engine off) remove the timing belt cover (upper), using a flash light inspect the condition of the belt, check for cracks especially at the base of drive teeth. An engine has a unique set of crankshaft, camshaft and accessory timing marks. Maintenance The timing belt or chain needs to be replaced per manufacturer's specification and can fail without warning which stalls the engine. Because a timing chain configuration is more durable, a timing belt will need to be replaced more often, comparatively. Easy to understand guide on how a timing belt works, this information...
