NOTE: If the vibration damper and crankshaft pulley have to be separated, mark the vibration damper and crankshaft pulley so that they may be reassembled in the same relative position. This is important as the vibration damper and crankshaft pulley are initially balanced as a unit. NOTE: If the vibration damper is being replaced, check if the original vibration damper has balance pins installed. If so, new balance pins (6A328 or equivalent) must be installed on the new vibration damper in the same position as the original vibration damper. The crankshaft pulley (new or original) must also be installed in the same relative position as originally installed. 8.

Refer to Crankshaft Pulley and/or Damper and/or Crankshaft Front Seal in this section. 2. If a new engine front cover is to be installed: Install oil pump and filter body . Clean water pump gasket surface. Position a new water pump housing gasket (8507) on the engine front cover and install water pump . Install water pump retaining bolts. Tighten to 20-30 Nm (15-22 lb-ft). 3. Lubricate crankshaft front seal with clean engine oil XO-10W30-QSP or -DSP or equivalent meeting Ford specification ESE-M2C153-E. NOTE: Gasket and Trim Adhesive D7AZ-19B508-B or equivalent meeting Ford specification ESE-M2G52-A is recommended to hold the engine front cover gasket (6020) in position while the engine front cover is installed. 4. Position a new engine front cover gasket on the cylinder block and install the engine front cover / water pump assembly using dowels for proper alignment. 5. Install the engine front cover retaining bolts. Tighten to 20-30 Nm (15-22 lb-ft). Install the capscrew (Part No. N804841) nearest the oil bypass filter flange last, and tighten last.

1. CAUTION: At no time, when the timing chain(s) are removed and the cylinder heads (6049) are installed, may the crankshaft (6303) and camshafts (6250) be rotated. Failure to follow these directions will result in valve and/or piston damage. NOTE: Because this is not a free-wheeling engine, if it has jumped time, there will be damage to the valves and pistons (6108) and will require the removal of the cylinder heads . The camshaft sprockets (6256) should only be disassembled from the camshafts when one of the components is to be replaced. Remove valve covers (6582) , oil pan (6675) and engine front cover (6019) as described. 2. Remove crankshaft position sensor pulse wheel. 3. Rotate engine to No. 1 top dead center (TDC). 4. NOTE: Cam Positioning Tool Adapters 303-413 (T92P-6256-A) and Cam Positioning Tool 303-380 (T91P-6256-A) MUST be installed on camshaft to prevent camshaft from rotating. Install Cam Positioning Tool Adapters 303-413 (T92P-6256-A) and Cam Positioning Tool 303-380 (T91P-6256-A) on flats of camshafts . 5. Remove two bolts retaining RH timing chain tensioner (6L266) to cylinder head and remove timing chain tensioner . 6. Remove RH timing chain tensioner arm (6L253) . 7. Remove two bolts retaining RH timing chain guide (6K297) to cylinder head and remove timing chain guide . 8. Remove RH timing chain from camshaft sprocket and crankshaft sprockets (6306) . 9. NOTE: Cam Positioning Tool Adapters 303-413 (T92P-6256-A) and Cam Positioning Tool 303-380 (T91P-6256-A) MUST be installed on camshaft to prevent camshaft from rotating. Remove two bolts retaining LH timing chain tensioner to cylinder head and remove timing chain tensioner . 10. Remove LH timing chain tensioner arm . 11. Remove two bolts retaining LH timing chain guide to cylinder head and remove timing chain guide . 12. Remove LH timing chain from camshaft sprocket and crankshaft sprocket . 13. If necessary, remove camshaft sprockets and crankshaft sprockets as described. 14. CAUTION: Do not rotate crankshaft and/or camshafts . Engine damage may occur. Inspect the plastic running face on timing chain tensioner arms and timing chain guides . If worn or damaged, remove and clean oil pan and oil pump screen cover and tube (6622) . Installation

Checking Timing An access plug is provided in the cam drive belt cover so that camshaft timing can be checked without removal of the cover or any other parts. 1. Remove the access plug from the cam drive belt cover. 2. Rotate the crankshaft so that the No. 1 piston is rising on compression stroke. 3. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TC mark on the belt cover. Always turn the engine in the direction of normal rotation (clockwise, as viewed from the front). Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner. 4. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover. 5. Install the belt cover access plug. Adjusting Timing Belt SPECIAL SERVICE TOOL(S) REQUIRED Description Crankshaft Belt Tension Adjusting Tool T74P-6254-A 1. Remove the outer timing belt cover as outlined in this section. CAUTION: Attempting to adjust timing belt tension without loosening spring pivot bolt will break Crankshaft Belt Tension Adjusting Tool T74P-6254-A when relieving tension on the belt. 2. If belt timing or tension is incorrect, loosen timing belt spring pivot bolt. 3. Hold tensioner with Camshaft Belt Tension Adjusting Tool T74P-6254-A. 4. While holding tensioner, loosen adjusting bolt and gradually release spring tension. Loosening Timing Belt Tensioner, 2.3L Tool Number 8 — 5. Using adjusting tool, pry tensioner away from belt. While holding, tighten adjusting bolt. There should be no tension on belt. Camshaft Timing Belt, 2.3L I-4 Timing Mark on Camshaft Sprocket Remove the bolts holding the crankshaft position sensor in place and pull the sensor assembly free of the dowel pin. 7. Remove the crankshaft pulley , crankshaft pulley hub and timing belt guide. 8. Remove the drive belt and inspect it for wear or damage. If the belt is damaged, replace it. 9. Remove one spark plug from each cylinder. 10. If not done: a. Loosen tensioner adjusting bolt. b. Using Camshaft Belt Tension Adjusting Tool T74P-6254-A, pry tensioner clockwise against spring tension as far as possible. c. Tighten adjusting bolt to hold tensioner in released position. 11. Align crankshaft so number one piston is at TDC (top dead center) as indicated by timing mark. 12. Line up camshaft sprocket timing mark with inner timing belt cover timing mark and key is pointing down.
