Questionhow do u set the timing marks on a chryler sebring 2005 2.4 liters 4 cylinder
AnswerHi Lyle,
This is a fairly complex explanation because of the tension adjustment which I can't do justice to because it covers about 8 steps and 3 figures.

PS:Here are the steps. Because of interference concerns, you should have aligned the timing marks before you removed the belt. If you have to move these sprockets to begin with and you think that were not moved since the belt was removed then I would put the belt on now and rotate all the sprockets until they are approximately where they should be and then begin the timing... If one or more sprockets was moved alone or the belt broke you will have to figure out how to get back to the approximate aligned position gradually so as not to damage the valves in this process...
1. Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.
2.Set camshafts timing marks so that the exhaust camshaft sprocket is a 1/2 notch below the intake camshaft sprocket (marks facing oneanother,arrows up), i.e. the intake sprocket mark should be at 9 0'clock and the exhaust sprocket mark should be at 3 o'clock but turned slghtly below the 3 position by 1/2 a tooth notch from where the cam is set.
CAUTION:ENSURE THAT THE ARROWS ARE UP ON BOTH SPROCKETS
3.Install the timing belt: Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets, and then around the tensioner.
4. Move the exhaust camshaft sprocket counter-clockwise to align marks and take up belt slack
5. Insert a 6 mm allen wrench into the hexagon opening located on the top plate of the belt tensioner pulley*. Rotate the top plate counter-clockwise. The tensioner pulley will move against the belt and tesioner setting notch will eventually start to move clockwise. Watching the movement of the setting notch, continue rotating the top plate counterclockwise until the setting notch is alighed with the spring tang. Using the allen wrench to prevent the top plate from moving, torque the tensioner lock bolt to 220 inch-pounds. Setting notch and spring tang should remain aligned after lock not is torqued.
6.Remove the allen wrench and torque wrench.
Note: Repositioning the crankshaft to the TDC position must be done only during the clockwise rotational movement. If TDC is missed, rotate a further two revolutions until TDC is achieved. DO NOT ROTATE crankshaft counterclockwise as this will make verification of proper tensioner setting impossible.
7. Rotate the crankshaft clockwise two revolutions to the TDC position. Verify that the cam and crankshaft timing marks are in the proper position.
8.Check if the spring tang is within the tolerance window. If the spring tang is within the tolerance window , the installation process is complete and nothing further is required. If the spring tang is not within the toleance window repeat steps 5 thru 8.
*The tensioner lock bolt should have been loosened whent he belt was removed, if not, do it now.
