General Motors — Cyclone Type Air Cleaner Servicing
Maintenance
From a General Motors operator's manual — check it applies to your exact model before use.
Before you start
- If left loose, dust will be drawn in and the air cleaner will fail to function properly.
Procedure
- Remove the dust cup and withdraw the element.
- On a double element type cleaner, do not remove the inner element when the outer element is cleaned.
- Remove the inner element only when the outer element is replaced; replace both elements at the same time.
- Prior to installation, clean the inside of the case and dust cup, and slowly insert the element.
- If placed horizontally, install the dust cup with the assembling direction indicating mark facing upward.
- Make sure the element and dust cup are securely installed.
