18 Steps

Obtain the correct replacement filter:

It should be the same as the one you will replace. Consult your vehicle service manual or auto parts store if you need assistance finding the right part.

Secure the vehicle:

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

Open the bonnet (hood):

Release the bonnet with the lever inside the car. Move the exterior bonnet catch for final release. Lift the bonnet and secure it with the prop rod.

Locate the air filter:

Air filter is located on the top of engine.

Remove the air filter cover:

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 out of the air conduit and lift it up so it comes off the lower part of the housing.

Take out the air filter:

Now you can see a round or rectangular filter made of cotton, paper or gauze. Filters have a rubber rim that seals off the unit’s interior. Simply lift the filter out of the housing.               

Clean the air filter housing:

Connect the air hose to the compressor and use the compressed air to blow out the dust, or use a vacuum cleaner to suck up any dirt. Seal the air conduit with removable adhesive tape. It only takes a minute and that way you won’t get any dirt into the engine whilst cleaning.

Replace the filter:

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.

Replace the cover:

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 the engine’s performance. 

Tighten all the screws or clamps:

recheck that you have put everything firmly back together by rocking the unit gently with both hands.  k. Shut the bonnet securely.

19 One of the most important aspects of customer service is that of what is often referred to as he Feel Good Factor. Basically the goal is to not only help the customers have a good experience, but to offer them an experience that exceeds their expectations. 

Several key points are listed as follows:

Know your product:

Know what products/service you are offering. In other words, be an information expert. It is okay to say ‘I don’t know’, but it should always be followed up by “but let me find out” or possibly “but my friend knows!” Whatever the situation may be, make sure that you don’t leave your customer with an unanswered question.

Body Language/Communication:

Most of the communication that we relay to others is done through our body language. If we have a negative body language when we interact with others it can show our lack of care. Two of the most important aspects of positive body language are smiling and eye contact. Make sure to look your customers in the eye. It shows that we are listening to them. And then of course, smiling makes the conversion more positive.

Anticipate Guest Needs:

Nothing surprises your customer more than an employee going the extra mile to help them. Always look for ways to serve your customer in more ways than they expect. In doing so it helps them to know that you care and it will leave them with the “Feel Good Factor” that we are searching for.

21 Sensitive air bag systems: 

In older model cars, the airbag deploys when a front-end crash occurs. However, many of today’s vehicles come equipped with more sensitive air bag systems, which sense the difference in the size and weight of the occupants and deploys the air bags accordingly. This technology may even be able to detect that an individual is not wearing a seat belt or that he or she is positioned abnormally in the seat and compensate the air bag deployment to accommodate this.
