Engine
NOTICE: Remove the cylinder heads before removing the crankshaft. Failure to do so may result in engine damage.
NOTICE: If the fuel rail is used as a leverage device, it may be damaged. Care must be taken when working around the fuel rail.
NOTE: During the repair or replacement of fuel-related components, cap, tape or otherwise appropriately protect all liquid and vapor fuel openings to prevent the ingress of dirt or foreign material. Remove all caps, tape and other protective materials prior to installation.
NOTE: For additional information, refer to the exploded views under Engine Engine - Assembly in the Assembly.

- Discard the gaskets and the bolts.
61. NOTICE: Make sure all coolant residue and foreign material are cleaned from the block surface and cylinder bore. Failure to follow these instructions may result in engine damage.
NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gaskets.
NOTE: Observe all warnings and cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block in the following sequence.
1. Remove any large deposits of silicone gasket material with a plastic scraper.
2. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4. Apply metal surface prep, following package directions, to remove any traces of oil or coolant and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
62. Support the cylinder head on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion. For additional information, refer to Engine.
63. Remove the 2 bolts and the CKP sensor.
64. Using the Strap Wrench to hold the crankshaft pulley, remove the bolt.
65. NOTE: If the pulley bolt is not installed, the tool will bottom out before the pulley is off.
