Oil Changes

Engine Oil

Engine oil is what lubricates a car’s engine, allowing it to run smoothly and last longer. Car owners must maintain a car’s engine by changing the oil and using the oil appropriate for their cars make and model. Every car comes with a “check oil” light and an oil filter under the hood. These components allow car owners to monitor their oil levels and add oil as needed without having to hire a mechanic.

Changing the Oil

An important part of routine car maintenance is changing the oil regularly. The necessary frequency of oil changes has become a point of contention among experts. The Engine Oil Bible maintains that engine oil can’t be changed often enough, but Nordic Group insists that, with the advent of detergent oils and multi-weight oils, some vehicles can go as far as 5,000 miles before needing an oil change. The best course of action is to check the owner’s manual and follow manufacturer’s recommendations.

An obvious benefit of changing one’s own oil is saving money, but oil change services frequently advertise bargains. If the “check engine oil” light comes on while driving, this is a strong indication that the car is running low on oil.  A driver does not need a mechanic to add oil. However, if the oil light stays on or lights up shortly after adding oil, there may be a leak, and a mechanic should look at the car.

Brake Service

Brakes are pretty much the most important safety device on your car. If you’ve ever partially lost your brakes in the past, you’ll agree that it’s not something you want to experience again. Inspecting your brakes twice a year for wear and damage can protect you and your passengers. Additionally, it will also help save you money by catching any damage before it becomes too costly.

Brake System Components That Can Fail

The master cylinder, the heart of the vehicle’s braking system, holds the brake fluid when it is not being delivered to the brakes through the brake lines. If brake fluid leaks because the master cylinder is worn or brake lines are plugged or broken, the fluid cannot be delivered, and the brake pads will become ruined.

The brake fluid itself can become dirty or contaminated as it draws rust-causing moisture and picks up other debris, or it can break down from excess heat. Clean brake fluid is either clear or slightly yellow, while dirty brake fluid may be brown or even black. Old and dirty brake fluid can damage ABS brake systems internally.

The brake lines connect to the master cylinder through a combination valve, which combines a metering and proportioning valve. It regulates the pressure on the front and rear wheels to make sure both sets of brakes are applied simultaneously. A malfunctioning combination valve may cause the wheels to lock up.

Brake pads and shoes can be made of ceramic, metal or organic materials, while the disc rotors and drums they press against are made of metal. Because the pads and shoes create friction to stop the car, they gradually wear down over time and may wear away completely, letting the metal of the calipers and cylinders they are attached to grind against the rotors and drums and damage them. Some pads have a metal strip attached that sounds a warning whistle when the pad becomes too worn, but this strip sounds only when the car is in motion and the brakes are not applied.

Transmission Service

Using the latest in state-of-the-art technology, we will install a safe and effective cleaner to suspend harmful varnish and sludge from the transmission valve body, torque converter and lines and install new high-tech fluid with conditioners.

Just like your engine, you should have your transmission serviced regularly. When Smith Bros. Garage, Inc. in Shrewsbury, [ST] services your transmission, we:

• • Remove and inspect the pan
  • Clean or replace the screen
  • Clean the pan
  • Reinstall the pan
  • Install a new gasket
  • Replace old transmission fluid with new, high quality fluid
  • Make any additional needed changes and adjustments

By replacing the old transmission fluid, the expert team at Smith Bros. Garage, Inc. essentially gives your vehicle’s transmission new life. The new fluid restores your clutch’s holding power. This reduces slip and heat production. Additionally, flushing the old fluid gets rid of small bits of clutch material and metal shavings, which can damage your transmission by clogging passages and wedging themselves between moving parts. Getting rid of the old fluid reduces wear within the transmission.
Replacing old fluid with new also provides better lubrication within the transmission, which boosts the holding ability of the transmission’s friction components. Improved lubrication also results in less heat. By decreasing friction and heat, your transmission will work better for a longer amount of time. A simple service can save you the money and time that come with a major transmission repair or replacement.

Fuel/Air Induction Clean-up

Over time, deposits build up on intake valves, injectors, ports, fuel injectors and combustion chambers within your vehicle. These build-ups can cause loss of power, shaky idling, hesitation, hard starting, misfire, pinging and knocking noises and, perhaps worst of all, poor gas mileage.

Our team of auto technicians at Smith Bros. Garage, Inc. in Shrewsbury, PA use specialized fuel system and air induction cleaners and conditioners to clean your vehicle’s fuel injectors, throttle body, intake valves, ports and air intake. These cleaners and conditioners remove harmful combustion chamber deposits from all these components, allowing your engine to run more smoothly. By cleaning the induction system thoroughly with specialized equipment and conditioners and cleaners, our team can make your vehicle run more efficiently.

The quality of the gasoline you put into your vehicle can vary greatly. When the gasoline is of poor quality, it can cause deposit buildup. Modern vehicles—especially those with gasoline direct injection—are particularly sensitive to deposits that build up in fuel injectors, intake valves and ports. Using specialized equipment, our mechanics will quickly and effectively clean the intake manifold, ports, intake valves and combustion chamber and install injector cleaning additives in your vehicle’s tank. This service will restore lost power and performance and will reduce harmful exhaust emissions.

Air Conditioning Service

The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle’s air conditioning unit is designed to move heat from the inside of your car to outside of it.

Your vehicle’s air conditioning unit has six major components:

• The refrigerant carries heat. In modern cars, refrigerant is a substance called R-134a. Older cars’ refrigerant is called r-12 freon, which is more expensive and difficult to find than R-134a.
• The compressor circulates and compresses refrigerant within the vehicle’s cooling system.
• Your vehicle’s condenser changes the refrigerant from gas to liquid and expels heat from the car.
• The expansion valve (sometimes called the orifice tube) is a nozzle that simultaneously drops the pressure of the refrigerant liquid, meter its flow and atomize it.
• Your vehicle’s evaporator transfers heat to the refrigerant from the air blown across it, cooling your car.
• The receiver or dryer filters your vehicle’s refrigerant and oil, removing moisture and other contaminants from them.

When you start your vehicle’s air conditioning system, the compressor works by putting the refrigerant under pressure, sending it to the condensing coils, which are generally in front of your vehicle’s radiator. The condenser expels hot air to outside the car, cooling the air within the vehicle. When this happens, the refrigerant is cooled, and it changes from a gas to a liquid, which then passes through the expansion valve and to the evaporator.

Once the evaporator receives the liquid-state refrigerant, it loses pressure and cools the remaining liquid. The vehicle’s blower moves air across the evaporator and into the vehicle’s interior. If you keep your air conditioning unit turned on, the refrigerant goes through this cycle continuously.

If any of these components is damaged, it can turn your cool car into a furnace during the summer months. Your vehicle’s air conditioning issue could be as simple as topping off refrigerant to replacing a valve. When your air conditioning unit is not working as it should, bring your vehicle to Smith Bros. Garage, Inc., conveniently located in Shrewsbury, PA. One of our trained air conditioning specialists will inspect your car’s air conditioner, all lines, the evaporator and the compressor for leaks and wear.
