Engine Gasket Surface Preparation

ENGINE GASKET SURFACE PREPARATION





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.

Never use the following to clean gasket surfaces:

- Metal scraper
- Abrasive pad or paper to clean cylinder block and head
- High speed power tool with an abrasive pad (1), 3M Roloc(TM) Bristle Disc (2), or a wire brush (3)

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

Only use the following for cleaning gasket surfaces:

- Solvent or a commercially available gasket remover
- Plastic scraper
- Sealing surfaces must be free of grease or oil residue. Clean surfaces with Mopar(R) brake parts cleaner (or equivalent)
