Your Vehicle’s A/C System

When the temperatures start to get high, you want to make sure that your vehicle’s A/C system is functioning properly. If not, you could end up driving across town sweating buckets as you go. If you want to ensure that your system works properly, you need to maintain it properly. Proper maintenance requires routine servicing and recharging of your unit. Let’s learn more about your A/C system and how it works.


How Does an Air Conditioning Unit Work?


Your air conditioning unit runs off of refrigerant. When refrigerant (a liquid) is added to your unit, it is pressurized and condensed until it is cooled. This cycle continues on for as long as your air conditioning unit is running.


The two most common types of refrigerant used today are R134 and R12. They are popular because they can be evaporated at low temperatures and can be condensed when temperatures are high. Like many of the liquids used within vehicles, these refrigerants can be damaging to the environment. As such, their usage is regulated and all air conditioning recharges must be carried out by a professional.


What Components is my A/C System Made up of?


  • The Compressor – The compressor is a pump that is driven by a belt and connected to the engine. As the name states, the compressor compresses the refrigerant and transfers it throughout the system.
  • The Condenser – When hot air comes from the compressor, it is the job of the condenser to cool that air. The hot air enters the condenser through the top and then circulates throughout it. As it does so, it begins to cool. Once the air is turned into a high pressure liquid, it is ready to exit the condenser.
  • The Accumulator – The accumulator is what holds the refrigerant. In addition to holding the refrigerant, it also makes sure that this liquid is the only thing that is transferred into the expansion valve.
  • The Thermal Expansion Valve – It is the thermal expansion valve that regulates the amount of refrigerant that enters the evaporator. As such, it helps to keep your vehicle cool, but not overly cold.
  • The Evaporator – Not only does your A/C system pump cool air into your car, it also works to absorb the heat that is inside. It is the evaporator that does this.


You may need to have your A/C system repaired if…

  • No cool air is discharged. If your A/C system only blows warm air, it may need to be recharged.
  • It is making noise. A noisy system usually means there is probably something wrong with your compressor.
  • The fan stops blowing air
  • The fan does not seem to be blowing a lot of cool air. If air is not blowing at full capacity, there could be something wrong with your electrical system.


If you want your A/C system to perform at its best, you need to keep it well maintained. As a general recommendation, you should have your air conditioning unit checked and flushed every two to three years.

Learning About Auto Fuel Systems

We all care about how our vehicle looks and functions, but most of us couldn’t care less about how the engine operates or any of the mechanics behind the functionality. But sometimes it can be interesting to learn about your vehicle. One question that many ask is “how does fuel reach my engine?” Prior to 1980, it was the carburetor that sent gas from the tank to the engine. Today, it does so through the help of the fuel system.


Some may think that the workings of the fuel system are more complicated than they really are. The truth is, it’s very easy to understand how fuel reaches the engine. Simply put, the fuel system collects gas from the fuel tank and transfers it to the cylinder chamber located in the engine. In more detail, the fuel sits in the tank until it is needed. Once it is, it is sprayed into the engine’s cylinder. Once the fuel reaches the cylinder it is vaporized and mixes with the air that is also in the chamber. Soon, the mixture of fuel and air will be burned, giving your vehicle the power it needs to run.


There are several different parts that make up the fuel system. Included within these are the tank, the pump, the line, the filter, and the injector. The fuel tank is what holds the fuel and the pump is what transfers the fuel through the filer and lines and into the injector.



As mentioned previously, the fuel system did not always work as it does now. In earlier days, it was the carburetor that powered the fuel system. However, as vehicles began to evolve, the functioning of the carburetor also needed to change. To be more specific, vehicle updates required manufacturers to add over 7 new circuits to the carburetor, making it way too complicated use. As such, it was eventually replaced with the fuel injection system which was much easier to manufacture, maintain, and repair.

Of course, today’s fuel injection system is significantly more efficient than the carburetor. Not only does it produce better gas mileage, but is also much more precise, injecting the exact amount of fuel that the engine needs.

Without your fuel injection system, your vehicle could not run. If there is a problem with your fuel injection system, your vehicle may not run efficiently. If you have any future issues with your fuel injection system, you should now know exactly where the problems could stem from.

Preventative Maintenance for your Vehicle

If you don’t perform regular maintenance checks on your vehicle, you could run into some costly repair bills. And while maintenance tasks will cost you money, they can also help to save you money. A quick maintenance task of $30 can help you to spot a potential $500 problem before is hits, thereby saving you a great deal of money in the long run. Let’s take a look at some of the many reasons why preventative maintenance is so highly recommended by mechanics.


What Makes Preventative Maintenance so Important?

 The main reason that most people engage in preventative maintenance tasks is because it can save them a great deal of money on hefty repair bills. As an example, a simply oil check can help you spot signs of low oil levels that can indicate leaks. Repairing a leak that is found will cost you money, but not nearly as much as it would cost you to replace the entire engine if the leak was never found and all oil leaked out of it.


In addition to saving you money, preventative maintenance can also improve the performance of your vehicle (helping to keep you safe), as well as extend its lifespan.


What do I Need to Check Regularly?

  • Brake fluid levels – If you notice that the level of your brake fluid suddenly drops, you may have a leak. When leaks are not dealt with properly, hydraulic pressure can decrease which can, in turn, affect your braking abilities and reduce your safety on the roads. You should check your brake fluid levels at least once a month and change them at regular intervals.


  • Motor oil – Your vehicle’s motor has several different jobs. Not only does it cool and clean the engine, but it also protects and lubricates it. As such, it is essential for your vehicle to function properly. If you don’t change your motor oil at regular intervals, you could cause damage to your engine, eventually leading to engine failure (and a very costly repair bill).


  • Oil filters – Your oil filter holds  a very important job; it helps to prevent dirt and particles from reaching, and causing damage to, your engine. Be sure to change your oil filters on a regular basis to prevent engine damage.


  • Air filters – Like oil filters, air filters also help to keep dirt away from your engine and should be changed regularly.


  • Transmission fluid – Transmission fluid is what your vehicle uses to help shift from gear to gear effortlessly. Without it, you could experience transmission failure – another hefty repair bill. Change your transmission fluid often.


  • Coolant – Coolant is used within a vehicle’s cooling system to prevent it from overheating. What would happen if your vehicle overheated? The engine would be destroyed and you would be stuck at home! Check your coolant levels often and change it anytime the fluid becomes discolored.


When it comes to vehicles, there are many different maintenance tasks that need to be performed. As such, the tasks listed above are just a few of the many and are designed simply to get you started. As a general recommendation, you should take your vehicle in for regular maintenance checks every 3000 miles. Doing so could prevent you from ending up with a $1000 repair bill.

How to Keep Your Vehicle Looking Like New

Let’s face it, vehicles aren’t cheap. As such, we want to do everything that we can to keep them looking like new. Not only will maintenance of your vehicle make it look good, but it will also improve performance, decrease repair bills, and increase resale value. If you perform small maintenance tasks regularly, keeping your vehicle in tip-top condition will be easy. Here are a few things that you may want to consider doing on a regular basis if you want to keep your car looking like new:

1) Clean and wax the exterior – Cleaning the exterior of your vehicle won’t just make it shine, but it will also help to prevent the paint from rusting. To clean your vehicle properly, start with a good wash and scrub to remove any built-up dirt or grime. In addition to washing the body of the car, also be sure that you remove any dust from the wheels. Once washed, give your vehicle time to dry. Then, wax it. As you go about cleaning and waxing, be sure to pay attention to areas that might often be neglected (such as the trim).

2) Vacuum once a week – Every time we step into our vehicle we load it with dirt from our shoes. If we don’t clean it regularly, this dirt can quickly build-up until our vehicle becomes almost unbearable to sit in. Always be sure to vacuum the seats, the floors, and spots that are difficult to reach (in the seats, under the seats). In addition, pay close attention to the floor mats which accumulate the greatest amount of dirt.

3) Wash your headlights – If you don’t wash your headlights, they can quickly become a victim of oxidation. When this happens, they can become foggy and dimmed, failing to do their job properly. And while they can be cleaned after becoming discolored, headlights are much easier to clean if maintained regularly. Before wasting any money on headlight cleaner, try toothpaste – it works wonders!

4) Clean the inside – Clean the inside of your vehicle just as often as you clean the outside. Use a damp cloth to clean seats, dashboards, and paneling. In addition, use protectant to help preserve your fabrics.

Not only should you follow the tips above, but you should also have your upholstery detailed one or two times each year. In addition, use engine shampoo every few months to remove any grime that is built-up on engine parts.

If you want to keep your vehicle looking and running like new, you need to treat it good. Keeping it clean is just one of the many ways that you can help preserve your vehicles youthfulness and beauty.

Learning about Hybrid Fuel Systems

Today’s society is becoming increasingly aware of environmental issues and everyone is trying to do their part in protecting the earth. One easy way to do your part is by switching to a hybrid vehicle. Completely eco-friendly, the hybrid car emits significantly less pollutants into the air than other vehicles. In return, it causes less smog and less damage to our environment. One of the hybrid’s most popular models, the Toyota Prius, is not only eco-friendly, but also has a smaller engine which makes it extremely good on gas.


When looking for a hybrid vehicle, there are several different models to choose from. One of the most common is the electric-petroleum model. The Toyota Prius being one of these, these vehicles are named as such because they are both electric and gasoline powered at the same time. The electric motor is used to power the wheels and the gasoline, well, we all know what that does.


Because hybrid vehicles are designed with internal combustion engines, they put a large amount of pressure on the fuel system to function properly. If the fuel system does not function efficiently, fuel will not be stored properly, will not stay clean, and will not make it to the engine’s cylinder.


One thing that the hybrid does have in common with other vehicles is that it uses the fuel tank to store gasoline. The difference is that hybrids are designed with a bladder fuel tank which is smaller than regular tanks. As fuel is added, the tank will expand. As it lessens, the tank will contract. Such a function leaves less room for fuel to evaporate and less vapor emissions are released into the air.


In addition to bladder fuel tanks, hybrids also have an EVAP (Evaporative Emission Control System). This system is designed specifically to help reduce emissions, ensuring that vapors for the fuel tank and fuel system are not released into the atmosphere.


While not all do, there are some hybrid’s that use two types of gasoline. Of course, different types of gasoline cannot be stored in the same tank. As such, vehicles that have this option generally have what is called a “parallel fuel system” or two different gas tanks.


There are several benefits that come along with owning a hybrid. Included within these are:

  • Your vehicle will release less harmful emissions into the air
  • Your fuel efficiency will be increased
  • Your vehicle will become more resistant to damage caused by extreme temperatures, shock, stress, or vibrations
  • Hybrids have cleaner engines in which oil lasts longer. As such, you will not have to pay as much in the way of maintenance fees.


As the health of the environment becomes more and more of a concern, we are likely to see more and more hybrid vehicles on the road. Not only are these vehicles eco-friendly, but they are also much more fuel efficient than other vehicles. In addition, they are built stronger and will rack up less in the way of repair bills than regular cars. What more could you ask for in a vehicle?
