REMOVAL & INSTALLATION



See Figures 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

The air cleaner element must be replaced every 2 years or 30,000 miles (48,000 km), whichever occurs first. This is a maximum interval; the filter should be checked periodically and replaced when dirty or obstructed. The air filter element is one of the cheapest forms of insurance for the engine. Never operate the engine with the filter element removed or the filter housing lid removed.

When buying replacement parts in the aftermarket, compare the replacement unit to the old one. Check that the diameter and height are identical. Cheap, poorly made filters will not seal properly, allowing dust and road grit into the engine.

  1. Unplug any electrical or vacuum connections on the air cleaner cover.
  2.  
  3. On 1994-95 4-cylinder Accords, remove the air cleaner duct by pulling it straight out. Now, loosen the screws from the battery set plate and push it away from the air cleaner.

  1. Using a damp, clean rag, wipe the inside of the air cleaner housing.
  2.  

To install:
  1. Install a new air cleaner element. Make absolutely certain the air filter element is properly seated; the lid will mate to the filter, sealing the housing and forcing all intake air through the filter.
  2.  

Air cleaner elements are not interchangeable, although they may appear to be. Make sure you have the proper element for the year and model.

  1. Fit the lid or cover onto the housing. Many round housings have arrows stamped into the metal; align the arrows before attempting to install the lid. Correct alignment insures a tight seal.
