Preventative Maintenance Services
The following services are recommended at the listed times or mileages. These recommendations are intended as preventative maintenance to extend the life of your car or light truck and help prevent unexpected breakdowns. They are based solely on time or mileage and not on visual or measurements unless specified.

Power Steering Flush
Every 2 years or 24,000 miles

Why: Oxidation by-products, hose material and metallic debris accumulate in the fluid. As contaminated fluid is pumped through the system under very high pressure, it causes abrasive wear in the pump and the rack assembly, leading to premature wear, pump noise, and erratic steering.

Transmission Flush
Every 2 years or 24,000 miles
Why: Oxidized fluid and oxidation residues can cause blockage of oil lines or filter screens. Deposits can also cause malfunction of delicate shift control mechanisms or even complete transmission failure.

Induction/Injector System Flush
Every 2 years or 30,000 miles

Why: Deposits that build up in the fuel induction system may cause driveability problems such as hesitation, surge, stalling, hard starting, rough idle and loss of power. Deposits that build up in the air induction system may cause rough idle, excessive exhaust emissions, loss of performance and loss of gas mileage.

Coolant System Flush
Flush annually

Why: When coolant is depleted of buffering ingredients it becomes extremely corrosive, literally eating holes in coolant system components, as well as clogging passageways in the radiator which may overheat the engine and cause damage beyond repair.

Should be checked for alignment every year, should be aligned minimum every 30,000 miles.

Why: Everyday road shock and general wear and tear can knock your alignment out of specifications. When that happens, control of the vehicle may be threatened and the tires may begin to wear unevenly and rapidly. Note: If your vehicle hits a severe bump or curb alignment should be checked.

Drivetrain Services
The drivetrain serves two functions: it transfers power evenly from the engine to all drive wheels and it varies the amount of torque. The drivetrain may include the differential, a transfer case (in four-wheel and all-wheel drive cars) and the transmission (see "Transmission Services").

Differential Service
Why is it important?

The differential is a special gear box located between the drive wheels of your vehicle. It allows the drive wheels to turn at different speeds, as they must when turning a corner. Over time, high operating temperatures can cause the lubricating fluid in the differential to break down, developing a gummy texture that doesn’t properly lubricate the gears. Replacing the fluid can help you avoid premature wear on the gears in the differential, and can even help reduce wear on drive-wheel tires.

What is the service?

The old differential fluid is removed and replaced with new lubricating fluid based on your vehicle manufacturer’s recommendations. Learn more about Differential Service in How Cars Work.

Transfer Case Service
Why is it important?

The transfer case is a special gear box found in four-wheel and all-wheel-drive vehicles. It sends drive power from the engine to the front and rear axles. In all-wheel-drive vehicles, the transfer case helps to shift power from one axle to another, depend.

A/C Evacuation and Recharge Service The function of an air conditioner is to help remove the heat and humidity from inside the passenger compartment of the vehicle. Powered by a belt, the air conditioning compressor compresses the refrigerant to pressurize it and pump it through the system. The refrigerant is pushed through a valve where pressure and temperature are reduced. The now-cool refrigerant travels through the evaporator in the passenger compartment. As a result, cooled air is blown into your vehicle. This refrigerant returns to the compressor, where the cycle begins once again.

Master Auto technicians will:
  • Visually inspect the air conditioning compressor drive belt for cracks or damage
  • Visually inspect accessible components for leaks or damage
  • Check the operation of the air conditioning compressor and other air conditioning components
  • Evacuate refrigerant from the system
  • Vacuum test the system
  • Recharge the A/C system using the appropriate refrigerant to the system capacity according to the vehicle manufacturer's specifications

PLEASE NOTE: The service is designed as a periodic maintenance service rather than a detailed troubleshooting or repair service. Master Auto technicians begin the service by checking for signs of leaks. We do not recommend servicing systems with detected leaks.*

Serpentine Belt Replacement
The serpentine belt transfers power from the engine to operate various engine components, including the alternator, water pump, power steering pump and the air conditioner compressor.

The service includes:
  • Visually inspecting the serpentine belt
  • Removing the old serpentine belt and installing a new serpentine belt
