All the dust and grit present in the air is kept out of the engine by means of the air filter element. Proper maintenance is vital, as a clogged element not only restricts the air flow and thus the power, but can also cause premature engine wear.
The filter element should be cleaned or replaced every 7,500 miles, or more often if the car is driven under dry, dusty conditions. Remove the filter element and using low pressure compressed air, blow the dirt out.
The filter element used on the Chevrolet Nova/Geo Prizm is of the dry, disposable type. It should never be washed, soaked or oiled.
The filter element should be replaced every 30,000 miles, or more often under dry dusty conditions.Carbureted Engine
- Unfasten the wing nut and clips on the top of the air filter housing and lift off the top.
- Lift out the air filter element; clean or replace it.
- Install the air filter, making sure the element is correctly centered. If a new element is being installed, make certain the height of the new one is identical to the old one. Proper sealing between the top of the housing and the filter is essential.
- Reinstall the top of the housing and attach the clips. Install the wing nut and tighten it snugly with your fingers.
- The air cleaner housing is located on the left front fender, just ahead of the shock tower. Locate and carefully remove the screws or unhook the clips, holding the top half to the bottom half of the housing.
- Lift the top of the casing just enough to remove the old filter. Be careful of other wires and hoses in the area.
- Install the new filter, making sure it is properly positioned in the housing.
