2004 Cadillac CTS Timing Belt Parts and Q&A

• Q: What tools are needed to service and repair the timing belt on 2004 Cadillac CTS?

  A: Service and repair of the Timing Belt requires a combination of Timing Belt alignment kit (J42069) and its parts (J42069-10, J42069-20, J42069-40) with crank hub torx® socket (J42098). After placing j42069-20 onto camshaft gears 1 and 2 make sure their marks match exactly before moving on; otherwise adjust the Timing Belt. The j42069-40 tool lets you align to the left of j42069-20 by turning the eccentric counterclockwise until it is correctly positioned then tightening the bolt to 40 nm (30 ft. Lbs.). Use j42098 and rotate crankshaft clockwise two revolutions until reaching 60 degrees before top dead center (BTDC). Then remove j42069-10 and j42069-20 from installation. Place the j42069-10 on the crankshaft sprocket before turning the crankshaft clockwise until the movable lever of the j42069-10 reaches the water pump pulley flange. Check that the crankshaft is not located 180 degrees beyond top dead center and verify that camshaft gear reference marks match the rear Timing Belt cover notches. Perform a reappraisal of the alignment steps when required. To position j42069-20 to the right side perform the same procedure while rotating the eccentric clockwise. Begin adjusting the Timing Belt Tensioner by first rotating the eccentric locking nut counterclockwise until reaching the established position for new or used belts and tighten it to 20 nm (15 ft. Lbs.). Proceed to torque the upper idler pulley bolt as you maintain the eccentric using tool j42069-40. Conduct the last check by rotating the crankshaft clockwise twice through 60 degrees btdc before putting back the j42069-10 tool and checking camshaft gear alignment using the j42069-20. The timing operation will continue when the gear marks consistently match. Move on to reassemble the parts while installing both the crankshaft balancer and Timing Belt cover.
