The oil filter sifts out contaminants, allowing the oil to flow through the engine unrestricted. Should the oil filter become restricted or clogged with contaminants, they will flow around the filter. This bypassing is a safety mechanism, but you never want to let oil and filter changes go so long that bypassing takes place. Stop by today and let us check your oil before major damage can occur to your engine
In order to meet Federal Exhaust Emission and Fuel Economy regulations, today's vehicles are equipped with highly sophisticated electronic engine control systems. These systems do not require periodic adjustments. The only services required on a scheduled basis are spark plug and filter replacement. In older cars however tune up are part of a regular maintenance regimen. Let Duffey Auto Services help maintain your older or newer vehicle.
We can help you choose the right battery for your vehicle and lifestyle. Our staff can safely and professionally install your battery and get you back on the road.
Exposure to heat, vibration and contamination makes belts and hoses wear out faster than any other components in your car. That's why regular inspections are so important.
Inspection/Maintenance programs evaluate the emissions from vehicles and single out those that are polluting beyond the limits established for certain model years of vehicles. Aside from identifying vehicles with high emissions, such programs advocate proper maintenance to prevent high emissions due to maintenance neglect.
Vehicle inspection is a procedure mandated by governments in many states, in which a vehicle is inspected to ensure that it conforms to regulations governing safety, emissions, or both. Inspection can be required at various times, e.g., periodically or on transfer of title to a vehicle. If required periodically, it is often termed periodic motor vehicle inspection; typical intervals are every two years and every year.
Clogged fuel injectors can cause your vehicle to run sluggish and can rob performance. And just off the shelf fuel injector cleaners are not enough. The proper steps in fuel injector system service are:
• Check fuel pump operating pressure and volume
• Test pressure regulator for operation and leakage
• Flush entire fuel rail and upper fuel injector screens to include pressure regulator
• Clean fuel injectors
• De-carbon engine assembly
• Clean throttle plate and idle air control (IAC) passages
• Check minimum air flow rate and adjust if needed
•

Tire rotation helps to equalize tread wear and is critical to gain the maximum life from your tire investment.
One of the leading causes of tire failure and casing rejection during the retread process is a faulty repair. This area is most often overlooked when fleets design tire maintenance programs, but as a recent survey from the monthly magazine Tire Business indicates, 46% of tire failures were caused by improper repair procedures. Of course this means higher tire costs.
When a radial tire has been damaged to the point where the steel cords are exposed to the elements it is important that the area be repaired as soon as possible so that moisture is not allowed to migrate along the belt package causing further damage.
The most effective method of repair for nail holes (1/4") is the plug and patch repair. The plug stops the migration of moisture and the patch on the inside of the tire supports the plug. For repairs larger than a nail hole (3/8" and larger) the tire should be removed from service.
This method of repair not only reduces the number of tire failures but promotes casing recovery as well. Our experienced professionals are trained to identify weather or not your tire can be safely repaired.
Proper wheel balance ensures that the wheels, while spinning, do not have a heavy spot that can cause vibration and premature wear of tires, struts, shocks and other steering and suspension components. When combined with proper wheel alignment, balanced wheels ensure smooth and enjoyable driving. Duffey Tire Service has state of the art wheel balancers to ensure your tires are performing properly.

The primary function of your cars suspension and steering systems is to allow the wheels to move independently of the car, while keeping it "suspended" and stable. Any play or uncontrolled motion in these systems results in a deterioration of handling and accelerated tire wear. Vehicle alignment is closely tied to the condition of the suspension and steering systems.
The heater in your car is basically a smaller version of your cooling systems radiator. Hot engine coolant is circulated through a small radiator, often times called a heater core. A fan is positioned in front of the heater core to blow cold outside air over the fins. As this air travels over the heater core, it heats up and becomes the hot air which blows out your heater vents. Like your engines cooling system radiator, the heater core can suffer some of the same issues. If the heater core becomes clogged with rust or sludge, you will no longer have heat. Also leaks can cause a cabin full of white steam and really mess up your windows. If you smell the sweet aroma of coolant when your heater is on, chances are, you have a small leak in the heater core. Often times the heater core is buried under the dashboard, and replacing it, is a major job.
The air conditioning system in your car is comprised of a compressor, condenser, expansion valve and evaporator. If you have ever used a can of compressed air to clean computer components, you will know that the bottle gets very cold in a short amount of time. This is due to the rapid expansion of the compressed gas. The same thing happens in your car’s air conditioning system. Refrigerant is compressed in the compressor and turns into a hot gas. In the condenser, this hot gas is cooled to a liquid state and travels to the expansion valve. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that eventually blows out your vents. Duffey Auto canter can keep the interior of you car cool by repairing your vehicles AC system.
Vehicles with automatic transmissions require transmission fluid. It protects the transmission from running too hot, especially during strenuous conditions such as towing or steep hills. If you will be putting more driving stress than normal on your vehicle, it's important to have your car inspected and serviced to prevent the transmission from overheating. However, completely flushing and replenishing your transmission fluid requires a specially-designed machine.
Complete brake service does not leave important things undone to save time and/or money. We are talking about things like rebuilding or replacing high mileage calipers and wheel cylinders, replacing disc and drum brake hardware, resurfacing or replacing drums and rotors, changing the brake fluid and bleeding all the lines, checking and adjusting the parking brake and even checking the ABS system.
Oil pressure light flickering? Engine knock? Both? Major repair problem or minor annoyance? Either way, you should always quickly investigate the source before it becomes an even bigger problem.
Does your vehicle start slowly? Do extreme temperatures affect your vehicle's ability to start? Does your vehicle need to be jump started? Any of these conditions may indicate the need for service or repairs to your vehicle's starting and charging system. Bring your vehicle in today to have one of our professionals check it out to see if you are in need of a new starter.
Think you have steering or suspension problems? Beside pulling and bouncing, telltale signs include uneven or excessive tire wear and poor steering control.
Auto radiator repair is a necessary fact of life for just about every car owner. Your car's radiator works like the air conditioner in your house to keep your engine cool. But radiators tend to get clogged, corroded, suffer from wear and tear, and develop leaks. The last thing you want is to have a problem develop when you are on the road, so properly maintaining your car's cooling system is vital to a safe and happy ride. According to experts, vehicles that are over five years old are most prone to radiator problems.
Even though alternators are generally sturdy, there are many reasons why they can stop charging properly. They’re often susceptible to heat. If you’ve been driving long distances in extremely warm weather, they can lose their ability to produce a current. They can also be damaged from voltage irregularities. For example, if you jump start a car and cross the jumper cables, the current can overload the alternator.
Also, its ability to produce a full current can be affected if one of the diodes goes bad. The diodes are essential for converting the output from AC to DC. If one of them is damaged or burns out, the alternator’s output can be diluted.
Our auto electrical specialists know that every year the technology for the electrical system in your auto becomes increasingly more complicated. The auto electrical system operates a wide arrange of components in your automobile, including the wiring and circuits, charging and starting system, mirrors and windows, instrumentation, lights, antilock brakes, and much more. If you are having problems with your car or truck starting and your troubleshooting has ruled out the battery or starter then the culprit may very well be the vehicle's electrical system.

Your car not only has to help keep your family safe, it has to do its part to keep the planet safe. Most people think their car’s exhaust system is designed only to reduce noise, but it is also responsible for reducing harmful emissions from entering the atmosphere. A properly functioning muffler and exhaust system not only sound better, they are better – for you, your car, and the environment.
The most important thing to know about timing belt replacement is that it is not an optional piece of car maintenance. Having the timing belt replaced at recommended intervals is critical to the smooth operation of a car. At the very least, a failed belt can put a car out of commission until a new one can be installed, but in some types of engines, it can cause a catastrophic engine failure, which is definitely undesirable.
The water pump pushes coolant through a vehicle's cooling system. The water pump is operated by a fan belt at the front of the engine or by the timing belt.
A failing water pump may start to leak coolant and/or make a rumbling sound as the water pump's bearings start to deteriorate.
To replace the water pump, the cooling system is drained and the fan belt or timing belt and pulleys are removed.
