The air cleaner is a paper element contained in a housing located either on the left side of the engine compartment (fuel injected vehicles) or over the carburetor. The air filter element should be inspected at each oil change and replaced, at least every 30,000 miles or 36 months, whichever comes first.
The air cleaner serves a dual purpose. It removes dust and dirt particles from incoming air in order to protect the internal engine parts. But it also acts as a flame arrestor in the event of an engine backfire. For this reason, the engine should never be started with the air cleaner removed from the housing or an engine fire could occur in the event of a backfire.
Check the air filter element more often if the vehicle is operated under severe dusty conditions and replace, as necessary.
REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Loosen the clamp, then separate the air duct from the air cleaner housing.
- For carbureted vehicles, remove the wing nut from the top center of the air cleaner housing assembly.
- Release the air cleaner housing hold-down tabs.
- Either lift the housing cover or separate the housing, then remove the air cleaner element and replace if dirty. If the element is only slightly dusty it can be cleaned by blowing compressed air through the element from the clean side.
- Wipe all dust from the inside of the housing using a clean rag or cloth.
- Install the element into the housing, then position the cover over the element.
- Secure the cover using the fasteners and, if applicable, the wing nut.
- Attach the air duct and secure using the clamp.
