| 2 - 3M ROLOC™ BRISTLE DISC |
| 3 - PLASTIC/WOOD SCRAPER |
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 or a wire brush (1). See Fig 1
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 or wood scraper (3). See Fig 1.
- Drill motor with 3M Roloc™ Bristle Disc (white or yellow) (2). See Fig 1.
CAUTION:
Excessive pressure or high RPM (beyond the recommended speed), can damage the sealing surfaces. The mild (white, 120 grit) bristle disc is recommended. If necessary, the medium (yellow, 80 grit) bristle disc may be used on cast iron surfaces with care.
