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

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

CAUTION: The use of unapproved cleaning methods can cause severe engine damage.

Only use the following for cleaning gasket surfaces:

- Solvent or a commercially available gasket remover.
- Plastic or wood scraper (4).
