What Is a Cabin Air Filter & When Should It Be Replaced?

by Leave a Comment

Many car owners have never even heard of a cabin air filter and would have no idea when it needs to be replaced if they had!  Hopefully the information here will answer the questions you might have about this unknown filter.

Cabin Air Filter

Dirty Cabin Air Filter

A cabin air filter is a part of your car’s ventilation system that removes pollutants from the air before they can enter the passenger compartment.  Cabin air filters can also be referred to as pollen or dust filters, interior ventilation filters, ACC filters, or passenger compartment filters.  A cabin air filter purifies the air as well as protecting the heater and AC components.  If the cabin air filter is dirty or clogged, the heating or air conditioning performance will suffer as well as the inside air filtration.  When this filter looses its effectiveness, you might notice unpleasant odors or reduced air flow from the cabin vents.  It is recommended to replace this filter at least once a year or every 12,000 to 15,000 miles.  It should be replaced more often if your car is driven in places with heavy pollution or dusty conditions.  Two types of filters are offered for replacement, single stage and multi-stage filters.  Single stage filters trap dust, large soot, and allergens.  Multi-stage filters use activated carbon that reduces toxic gases and odors as well as dust and allergens.  Multi-stage filters are usually the better quality filter and more often recommended.

This filter is a relatively new feature and not all vehicles have one.   If you own a 2000 or newer car, it probably has one.  Cars and trucks in the U.S. began using cabin air filters around 1995, so check your owner’s manual or talk to your repair technician.  Most repair technicians  will be able to tell you whether or not your vehicle has one.   The ease or difficulty of replacing the filter depends on the make and model of your vehicle.  You might have to have it replaced by a technician.  Once you know whether your car is equipped with one or not, then you’ll know if you need to add” check cabin air filter” to the list the next time your car is serviced!

Transmission Trouble

Has your car lost its get up and go?  Here are five things to look for if you think your car might have transmission trouble.

  1. Lack of Response- Your car shouldn’t hesitate when shifting or refuse to go into gear.  If the engine speeds up when you step on the gas pedal but the car doesn’t, or if the car’s passing gear won’t engage, those could be signs of trouble.
  2. Whining, Clunking or Humming- Your car should shift quietly when it’s running correctly.  The sounds can vary but you should have your car checked if you notice new noises that can begin irregularly then grow in frequency.  If caught early you can avoid costly repairs.
  3. Grinding or Shaking- Your car should shift smoothly from gear to gear.  If you are experiencing any jarring or shimmying when your car shifts you might have transmission trouble.
  4. Check Engine Light- Newer cars have sensors that pick-up small irregularities in the engine and notify the computer that something is wrong.  These sensors can detect vibrations and early problems that you can’t even feel or see.  The check engine light can  also alert you to other issues that might be going on with your car.
  5. Leaking Fluid- Transmission fluid is vital to your car’s shifting ability and should be checked regularly.  The transmission fluid should be bright red, clear and smell sweet if parts are working correctly.  The fluid shouldn’t be dark in color or have a burnt smell.  Unlike motor oil, transmission fluid isn’t burned up so if the fluid level is low it is very possible you could have a leak.  The transmission fluid runs through a filter to help keep it clean.  This  filter should  be replaced according to your manufacturers recommendations so it doesn’t become clogged.   

Just being aware of the signs of possible transmission trouble and looking out for them can help you keep your car on the road and running smoothly.

Do You Need New Brake Pads?

by Leave a Comment

Brakes are one of, if not the most important safety devices on your car!  They should be maintained and inspected regularly to insure your safety and the safety of your passengers.  There is a simple way to determine if you need new brake pads.  Just stop, look and listen!  If your car doesn’t stop when you press on the brake pedal, that is a sign you might  need new brake pads!   If your car pulls to one side or the other when braking, or if the brakes grab or vibrate, those are also signs you might  need new brake pads.   Look at the brake pads. In order to really see the condition of the brake pads the wheels on the car need to be removed.  If the pad depth is less than 1/4 inch, they need to be replaced soon.  If you don’t trust your own judgment have them inspected by a professional. When the safety of your family is riding on your decision, don’t take chances.   Listen for a high pitched squeal.  Manufacturers have built a soft-metal wear indicator into the brakes to alert the driver when the brake pads need changing.  Unfortunately, if you hear a grinding sound that means the brake pad replacement is long overdue and the worn brake pads may have damaged the brake rotors.  Replacing your rotors can be a very costly job; so don’t let your brake pads get to this point!

We are quickly approaching the time of year when snow is a good possibility and no one wants to be driving in the snow with brakes that might not work!  So have your brake pads checked and replaced if needed.  You’ll be glad you did!

Finding a Good Auto Repair Shop

by Leave a Comment

None of us want to be looking for an auto repair shop when our car is in need of major repairs, but finding a good repair shop can sometimes seem a bit overwhelming!  Here are some tips to help you find a good auto repair shop. 

  1. Ask trusted friends, family and co-workers if they know a reputable repair shop.  Word of mouth is usually the best form of advertisement.  Ask them if the service they received was done on time and at the quoted price.  Following the advice of people you trust is always wise.
  2. Check consumer reports online. The internet is a good source of information and you can find other opinions regarding certain auto repair shops, whether the experience was good or bad.
  3. Check with the Better Business Bureau.  Once you find a shop you are interested in trying, they can tell you if there have been any reports filed against them.  Simply log onto www.betterbusinessbureau.com for information free of charge.
  4. Ask about the mechanics training and credentials. Most mechanics will have a general certification and some mechanics have gone on to specialize in certain fields.
  5. Compare rates.  There can be significant price differences between auto repair shops when it comes to parts and labor.  Make sure you know and are comfortable with what you will be charged for their services.
  6. On your first visit to your chosen repair shop, look for a clean well-organized work area and office. This will give you an idea as to how they run their business.   Do you expect to get good and dependable service if the place is a mess?

Once you find a good auto repair shop and are pleased with your  decision, let them know!  We so often complain about the things we don’t like but fail to mention the things we do!  Tell your repair shop when you’re happy with them and don’t forget to say a simple thank you when you pick up your car.  A few kind words can change a “good” auto repair shop into a “Great” one!
