Steps to change your Air Filter

 

 

  1. Secure the vehicl Park the car on level ground and apply the parking brake. Shift into first gear (manual transmission) or Park (automatic transmission) and then turn off the ignition.

 

  1. Locate the Air Filter Housing. It will usually look like a black plastic box. The air filter housing is usually situated near the engine, on the side of the engine bay. Fuel-injected cars tend to have a square or rectangular air filter. Typically, it has a big air intake hose connected to it.

 

  1. Sensors and Hoses. Some Air Filter Housings may have a sensor or a hose plugged into the side of the Intake Hose. Refer to your Owner’s Manual or Repair Manual if you have one of these and if it needs to be unplugged before you remove the top of the Air Filter Housing.

 

  1. Remove top of Air Filter Housing. With a damp clean rag wipe off any dirt, so it doesn’t fall into the housing. Now use the appropriate tool, as indicated in your Owner’s Manual or Service Manual. Loosen the hose clamp that seals the air conduct. Undo all the screws holding the air filter cover. Some models have wing nuts; other air filters are just clamped on with a quick release system. Keep screws and other parts together and in a safe location so you can find them later. Pull the cover up and out of the air intake and lift it up so it comes off the lower part of the housing.

 

  1. Remove the old filter carefully. The old air filter should be pulled out by hand, no tools are need.

 

  1. Clean the compartment. Be careful that no dirt or debris falls into the carburetor or the intake hose during this process.  If you have excessive dirt or debris inside the compartment, vacuum it out before installing the new filter.  Never blow out the dirt or debris, it may go into the air intake hose. Use a clean rag to wipe any dirt and debris from the housing and the seal that you could not vacuum out.  Now is a good time to check for cracks or damage to the interior and exterior of the housing and air intake hose.

 

  1. Compare filters. Before you throw away the old filter, compare it with the new filter to make sure they are the same size and shape.

 

  1. Install new filter in and close cover. Replace the old filter with a new one. Simply insert it into the housing with the rubber rim facing up. Make sure the edges are sealed by the rubber rim. Carefully insert the cover back into the air conduit and then press the entire piece down onto the lower half of the air filter unit. Make sure it’s on straight and securely; otherwise you could alter engine performance. Tighten all the screws or clamps and recheck that you have put everything firmly back together by rocking the unit gently with both hands.

 

  1. Mark your calendar. Generally, it’s best to replace the air filter every 15,000 miles. If you drive in dusty or dirty conditions, it is suggested to inspect more often. Most people change the air filter every other oil change.
