Engine Diagnostics

Vehicles with “driveablity” problems require the performance of diagnostic
procedures to determine the cause. Components are tested, their condition
recorded and compared to the manufacturer’s specs.

Transmission Service

Replace fluid, pan gasket and filter on vehicles so equipped. Most cars and
light trucks. Additional costs for special gaskets and filters if needed. Limited
warranty for 12 months/12,000 miles, whichever comes first.

Air Conditioning

The following components are inspected:

  • Performance test system
  • Leak test all connections
  • Check drive belts and hoses
  • Check heating and cooling systems

Batteries

The following components are inspected:

  • Visual inspection
  • Battery cable connections
  • Battery hold-down hardware
  • Battery case condition
  • Electrolyte level (where applicable)
  • Battery load test

Belts & Hoses

The following components are inspected:

  • Visual inspection
  • Checked for glazing, cracking, peeling and softening
  • Checked for proper tensioning
  • Checked for proper alignment of drive pulleys
  • Condition of each belt is recorded

Electrical System

The following components are inspected:

CHARGING SYSTEM

  • Visual inspection
  • Alternator drive belt
  • Alternator mounting brackets
  • Electrical connections
  • Charging system test

Alternator output (current) and voltage are tested.

STARTING SYSTEM

  • Visual inspection
  • Starter cable connections
  • Starter mounting bolts and brackets

Starter Electrical “Draw” Test measures the amount of electrical energy required
to turn the engine over during cranking.

Suspension System

STEERING

  • Tie rod ends (inner and outer)
  • Idler arm
  • Pitman arm
  • Rack and pinion unit
  • Rack and pinion bellows boots

CV Joint/Boots (Constant Velocity Joint/Boots)

A CV Joint is a flexible coupling that allows for changes in the angle between rotating
shafts without affecting the rate of rotation of the drive wheels; the CV Boot protects the
CV Joint from dirt and water.

Inspection includes a visual inspection of the CV boots for tears, splits or leakage of
lubricant. The vehicle is test driven to listen for noises while accelerating and turning.
Includes a visual inspection of U-Joints for loss of lubricant and inspected for excessive movement due to worn components.

Exhaust System

The exhaust system is a complex automotive assembly which has a series of functions
to perform, including carrying engine exhaust gasses safely to the rear of the vehicle,
reducing the engine sound level, maintaining engine performance and reducing harmful emissions through the use of a catalytic converter. Follow maintenance recommendations
of your vehicle manufacturer carefully.

Heating and Air Conditioning

The following components are inspected. Their condition is recorded and compared to manufacturer’s specs. Recommendations are made per the Motorist Assurance Program
Uniform Inspection Guidelines:

Visual Inspection:

  • Interior controls and blower
  • Radiator coolant level, hoses, pressure cap and thermostat
  • The A/C compressor belt for condition and tension
  • Leaks and other damage
  • Component condition, leaks and damage

Heating and Air Conditioning Tests:

  • Pressure test engine cooling system
  • A/C system pressures are measured and compared to manufacturer’s specifications
  • A/C system is leak tested
  • Both the heater and the A/C are performance tested by checking the outlet air temperature at the discharge vents

Shocks & Struts

Shocks and struts are safety components that maintain vertical loads placed upon the
tires. They control spring and suspension movement to keep tires in contact with the
road. Shocks and struts do wear out and should be checked every 12,000 miles just to
be safe. Worn shocks and struts affect vehicle safety.

Wiper Blade Service

Inspect wiper blades every six months (or more often if you notice wear or damage). A
good rule of thumb for timing is daylight saving time, when many other household items
are inspected and checked.
