Tools Required:

 

Removal

  1. Refer to Water Pump Removal. Perform all steps except removal of the pump. Leave water pump attached to the front cover.
  1. Drain the crankcase.
  1. Remove the crankshaft pulley from the crankshaft vibration damper. Remove the damper attaching capscrew and washer. Install Crankshaft Damper Remover T58P-6316-D on the crankshaft vibration damper. Remove the vibration damper.



    NOTE: Cover the front oil pan opening while the cover assembly is off to prevent foreign material from entering the pan.

  1. Remove the oil pan-to-cylinder front cover attaching bolts. Carefully separate the cylinder front cover from the oil pan gasket. Remove the cylinder front cover and water pump as an assembly.

    If a new front cover is to be installed, remove the water pump from the old cylinder front cover and install it on the new cover.

  1. Discard the cylinder front cover gasket.
  1. Check the timing chain deflection. Refer to Section 03-00.
  1. Crank the engine until the timing marks on the sprockets are positioned.



  1. Remove the camshaft sprocket capscrew and washer. Slide both sprockets and the timing chain forward, and remove them as an assembly.



 

Installation

  1. Position the sprockets and timing chain on the camshaft and crankshaft simultaneously. Ensure timing marks on the sprockets are positioned.
  1. Install the washer and camshaft sprocket capscrew. Tighten the sprocket capscrew to 54-61 Nm (40-45 lb-ft).
  1. Clean the cylinder front cover and the block gasket surfaces.
  1. Install a new oil seal in the cylinder front cover.
  1. Lubricate the timing chain with clean engine oil XO-10W30-QSP (ESE-M2C153-E) or equivalent.
  1. Coat surface of the oil pan gasket with sealer. Apply Silicone Rubber D6AZ-19562-AA or BA (ESB-M4G92-A and ESE-M4G195-A) or equivalent at the corners.

    NOTE: Gasket and Trim Adhesive D7AZ-19B508-AA (ESR-M11P17-A and ESE-M2G52-A) or equivalent is recommended to hold the gasket in position during assembly.

  1. Coat the gasket surfaces of the block and cover with Perfect Seal Sealing Compound B5A-19554-A (ESR-M18P2-A and ESE-M4G115-A) or equivalent, and position a new gasket on the block.
  1. Position the cylinder front cover on the cylinder block. Use care when installing the cover to avoid seal damage or possible gasket mislocation.
  1. Install the cylinder front cover to seal alignment tool into proper position.
  1. It may be necessary to force the cover downward to slightly compress the pan gasket. This operation can be facilitated by using Front Cover Aligner T61P-6019-B.
  1. Coat the threads of the retaining screws with oil resistant Pipe Sealant with Teflon® D8AZ-19554-A (ESG-M4G194-A and ESR-M18P7-A) or equivalent and install the screws. While pushing in on the alignment tool, tighten the oil pan-to-cover retaining screws to 16-24 Nm (12-18 lb-ft).
  1. Tighten the cover-to-block retaining screws to 16-24 Nm (12-18 lb-ft). Remove the pilot.



  1. Apply Multi-Purpose Grease D0AZ-19584-AA (ESR-M1C159-A and ESB-M1C93-A) or equivalent to the oil seal rubbing surface of the vibration damper inner hub to prevent damage to the seal. Apply Silicone Gasket and Sealant F1AZ-19562-A (WSE-M4G320-A2) or equivalent to the keyway before installing on the crankshaft.
  1. Line up the crankshaft vibration damper keyway with the key on the crankshaft. Install the vibration damper on the crankshaft using Crankshaft Sprocket and Damper Replacer T52L-6306-AEE. Install the capscrew and washer. Tighten the screw to 95-122 Nm (70-90 lb-ft). Install the crankshaft pulley.
  1. Refer to Water Pump Installation. Perform all the required steps except installation of the pump.
  1. Fill the crankcase with the proper grade and quantity of engine oil.
  1. Fill and bleed the cooling system.
  1. Operate the engine at fast idle. Check coolant and oil leaks. Check and adjust the ignition timing.
