  • Timing Belt Replacement
    Gary's Auto Repair will always include new idler and tension pulleys, and (timing belt driven) water pumps in our Timing Belt Replacement Service. When we service your vehicle's timing belt you can rest assured it will not fail prematurely due to a worn out pulley or water pump.

  • Fuel Injection Flush
    We will disable your vehicles fuel system and run our flush solvent throughout the fuel system components. The throttle plate and bore are cleaned by our technicians when we are flushing the fuel system. This service not only cleans injectors and the throttle area, but also removes deposits from the intake valves.
Factory Recommended Maintenance Services

Major maintenance services are usually recommended every 30,000 miles. We will follow your vehicle's manufacturer's recommendations. What is required will vary, but the following items are often called for:

    • Spark Plug Replacement
    • Fuel and Air Filter Replacement
    • Interior Ventilation Filter Replacement
    • Tire Rotation and Balancing
    • Oil and Filter Change
    • Complete Vehicle Lubrication
    • Complete Vehicle Inspection
      - Inspection Report with every major maintenance service.
  • Brake Fluid Flush
    We will remove and replace your vehicle’s brake fluid and bleed the entire system. Brake fluid absorbs moisture and this service helps protect your braking system from the potential corrosion and rust damage that moisture can cause.

  • Air Conditioner Systems Service
    We service both current systems equipped with r134a refrigerant and older systems with r12 refrigerant. It is not possible to determine the source of a refrigerant leak until the system is filled or re-charged. Once full we add a leak detection dye. If there is a major leak we can usually determine its source the same day. With minor leaks it may take several days or even months for the system to become low enough to fail. If the system fails within 1 year the leak detection dye will enable us to locate the source of this leak.

  • Diagnostic Services
    We retrieve stored codes, analyze live data, consult wiring diagrams and test individual components to determine the root cause of the problem. Along with computer scanners and ignition diagnostic machines, the most common tool used today is a lab scope. To test an individual component accurately, we must tap into the wiring at, or as close to, the component, as possible, to see the actual signal from it. We then test the signal at the computer. This signal is often corrupted before it gets to the computer. Gaining access to the component to test it often involves removing various brackets or components.
    The first level of diagnostic service includes reading computer codes and data, road testing the vehicle and basic component testing. This is all that is needed 80% of the time. If more diagnostic work is needed the customer will be contacted and consulted about what was found and what work is still needed.

  • Automatic Climate Control System Services
    The ASE Master Certified Technicians at Gary's Auto Repair can diagnose and repair today's automatic climate control systems. This requires intricate diagnostic ability to access and test various components involved. After the cause of failure has been diagnosed an accurate estimate of repairs will be offered to the customer.

  • Engine Tune-up
    We will replace your vehicle’s spark plugs, fuel filter, air filter, and PCV valve. Some vehicles have platinum spark plugs, which only require replacement every 2nd tune-up. We also recommend ignition wires and distributor caps be replaced at least every 3rd tune-up, or at 90,000 miles.

    Please note: A tune-up is a maintenance service. Check engine light warnings, drivability symptoms and state emission test failures all require diagnostic time to determine the proper remedy.

  • Engine Replacement
    We often install re-manufactured engines. Along with the replacement engine we always replace common maintenance items such as the spark plugs, thermostat, ignition wires, engine filters, water pump, drive belts and all engine filters to help ensure trouble free operation. Most carry a 3-year / 75,000 mile nationwide parts and labor guaranty.
    A used engine is often a cost effective alternative when a quality low mileage replacement is available. Used engines have much shorter warranty periods than re-manufactured engines, and may not cover all or any of the installation labor charges.

  • Four Wheel Alignment
    We will recalibrate adjustable front-end components to bring alignment angles back to factory specifications. We will provide a computerized print out of the before and after alignment measurements compared to the factory specifications for your vehicle.

  • Coolant System Flush
    We will flush the coolant system and replenish your vehicle's coolant. We will also bleed the air from the coolant system and run the vehicle long enough to ensure coolant circulation.

  • Coolant System Flush
    We will flush the coolant system and replenish your vehicle's coolant. We will also bleed the air from the coolant system and run the vehicle long enough to ensure coolant circulation.

  • Oil Change
    Includes changing your vehicle’s oil and filter and up to 5 quarts of oil. We will also lubricate the front-end if equipped with grease fittings.
    *Additional charges apply to premium application oil filters or canister type filters, over 5 quarts of oil and for synthetic oil.

  • Tire Balancing & Rotation
    Computer Road Force Balance and Rotate your vehicle’s tires. Tighten lug nuts to proper torque specifications.

  • Transmission Fluid and Filter Change
    We will either replace the transmission filter and pan gasket, or flush and replenish the transmission fluid or both. When the pan gasket and filter are replaced much of the fluid remains within the transmission and does not get replaced. When the fluid is flushed and replenished the filter and pan gasket (a common leak source) are not replaced. We usually recommend a complete fluid replenishment as well as the filter and pan gasket replacement.
    Please Note: Some vehicles today use synthetic fluid (most of these are not fitted with dipsticks so the wrong fluid cannot be added). The replacement interval on vehicles with synthetic fluid is usually 100,000 miles.

  • Transmission Replacement
    Replacing your car’s transmission is an expensive service. The quality of the re-manufactured transmission is more important than the price. A cheap job that fails is much more expensive than a quality product. Working with a transmission re-manufacturing facility that we have had a relationship with for many years, makes us confident we are delivering the highest quality unit to our customers. Warrantee is usually 12 months or 12,000 miles (which ever comes first).
    We usually recommend re-manufactured automatic transmissions and offer used standard transmissions. Used automatic transmissions are prone to failure while a re-manufactured standard transmission is often not cost efficient.

  • MotoVac Carbon Clean Service
    Since your car was new, dirt, varnishes and carbon deposits have been forming in your vehicle's fuel system, on the intake valves and in the combustion areas. These contaminants can rob your vehicle of performance, fuel economy, increase harmful emissions and could lead to costly engine repairs if left untreated.


  • Complete Vehicle Inspection
    We will perform a complete vehicle inspection and return to the customer with a detailed report with recommendations on service areas and preventative maintenance.


General Notice: Repair procedures outlined herein will vary from vehicle to vehicle and may change entirely without advance notice.
