Dodge Journey: Cleaning, inspection

CLEANING

To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of aluminum engine components and multi-layer steel cylinder head gaskets.

NOTE: Multi-Layer Steel (MLS) head gaskets require a scratch free sealing surface.

Remove all gasket material from cylinder head and block. Be careful not to gouge or scratch the aluminum head sealing surface.

Clean all engine oil passages.
