ENGINE MAINTENANCE

Engine maintenance is vital to keep your car or truck operating at peak performance. It also impacts the longevity of your vehicle's engine. Trust the experts at Twin Ridge Auto and Light Truck Service to help you protect your investment. Call us at 301-829-6100 or visit our shop in Mt. Airy 21771.

These are some of the engine maintenance services we offer.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system

You can count on the experts at Twin Ridge Auto and Light Truck Service to help your diesel engine last a long time.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 301-829-6100 or visit Twin Ridge Auto and Light Truck Service today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Twin Ridge Auto and Light Truck Service today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Twin Ridge Auto and Light Truck Service in Mt. Airy, MD 21771. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Twin Ridge Auto and Light Truck Service, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 301-829-6100 or visit Twin Ridge Auto and Light Truck Service today.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Twin Ridge Auto and Light Truck Service in Mt. Airy, MD 21771.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Twin Ridge Auto and Light Truck Service, we can pull the code and diagnose the problem for you. Give us a call at 301-829-6100 or stop by the shop for our expert assistance.


What Our Customers Are Saying

We have had Scott and Earl work on our cars for over 20 years. They helped us get 430K out of our Toyota Echo before the A/C failed and it just didn't make economical sense to repair. We know they will always give us an honest opinion on what needs to be done and charge a fair price. They are a pleasure to work with.


-Stephen S.

Scott, Eric and the gang are a good bunch to work with. Having worked in the industry myself for a number of years, I know when a shop doesn't have it's stuff together. They are honest and do a good job.....what more could you ask for?


-Craig K.

Trustworthy, kind, and fair. What else could you want or expect from your mechanic? We wouldn't take our cars anywhere else.


-Janine M.

Great service and I can trust them with my car. Highly recommended.


-Michael C.
