Engine














NOTICE: 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.

NOTE: If the cylinder head(s) is replaced, a new secondary timing chain tensioner will need to be installed.

NOTE: For additional information, refer to the exploded view under the Assembly procedure.
