- 1.NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
Drain the cooling system. Refer to Cooling System Draining, Filling and Bleeding .
- 2.
For 3.5L Twin Independent Variable Cam Timing (Ti-VCT) engines, remove the engine front cover. ENGINE - 3.5L TI-VCT .
- 3.
Rotate the crankshaft clockwise and align the timing marks on the intake VCT assemblies as shown in illustration.
- 5.NOTE: 303-1248 will hold the camshafts in the TDC position.
Install 303-1248 onto the flats of the LH camshafts.
- 7.NOTE: 303-1248 will hold the camshafts in the TDC position.
Install 303-1248 onto the flats of the RH camshafts.
- 8.NOTE: The 3 steps are for primary timing chains which have colored links that are not visible.
Mark the timing chain link that aligns with the timing mark on the LH intake VCT assembly as shown in illustration.
- 9.
Mark the timing chain link that aligns with the timing mark on the RH intake VCT assembly as shown in illustration.
- 10.NOTE: The crankshaft sprocket timing mark should be between the 2 colored links.
Mark the 2 timing chain links that align with the timing mark on the crankshaft sprocket as shown in illustration.
- 14.NOTE: Removal of the VCT oil control solenoid will aid in the removal of the primary timing chain.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid free of dirt and debris.
Remove the bolt and the LH intake VCT oil control solenoid.
- 15.NOTE: Removal of the VCT oil control solenoid will aid in the removal of the primary timing chain.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid free of dirt and debris.
Remove the bolt and the RH intake VCT oil control solenoid.
- 17.NOTE: Do not use power tools to remove the bolt or the LH primary timing chain guide may be damaged.
Remove the bolt and the upper LH primary timing chain guide.
- 18.NOTE: The VCT oil control solenoids are removed for clarity.NOTE: 303-1530 is inserted through a hole in the top of the mega cap.
Compress the RH secondary timing chain tensioner guide and let install 303-1530 in the hole on the rear of the secondary timing chain tensioner guide and let it hold against the mega cap to retain the tensioner in the collapsed position.
- 21.NOTE: Do not use power tools to remove the bolt or the RH primary timing chain guide may be damaged.
