As a complimentary service, we check all of the above items when you have your oil changed at AJ's Auto Repair.  We strive to anticipate the needs of our customers and develop the plans necessary for meeting those needs.  After every oil change, we will provide you with a complete breakdown of the inspection of your vehicle, and highlight any specific areas that need to be addressed in order to maintain the reliability and safety of your vehicle.

  • Inspect for water leaks
  • Inspect for fluid leaks
  • Inspect condition of hoses
  • Check starter operation
  • Check fuel delivery system for leaks
  • Check A/C and heater operation
  • Check wheel bearings
  • Check tire pressure and tread wear
  • Inspect steering
  • Inspect exhaust system
  • Inspect interior and exterior lighting
  • Check for warning lights



Many preventative services are based off of elapsed mileage.  There are several services to pay attention to aside from the normal 30k, 60k, 90k, 120k maintenance services that are suggested by your vehicle manufacturer.  Below are a list of services and their recommended service mileage.

  • Have your air filters replaced if needed.  A clean cabin air filter helps protect those with allergies by filtering out dust, pollen, and other contaminants.  A clean engine air filter helps to ensure smooth airflow to the engine, and helps keep gas mileage high.
  • Have your Air Conditioning checked for proper operation.  Recharge with additional coolant as needed.
  • Check all fluids and top off as needed.  Inspect fluid reservoirs for cracks and leaks.
  • Inspect tires to make sure there is no abnormal wear due to poor alignment.  Have tire pressure adjusted to ensure proper traction and tread wear.
  • Have your cooling system inspected to limit the chances of overheating during hot weather.
  • Have your battery and battery connections checked for proper operation and corrosion.  The computer systems in modern day vehicles must see the proper voltage in order to instruct the operation of the many systems, modules, and components in the correct fashion.
  • Have your brake system inspected for proper operation.  This includes all brake lines, calipers, rotors, drums, pads, and shoes.  Clean   and adjust as needed.
  • Have your vehicle evaluated for a cooling system flush.  Making sure that the coolant in your vehicle is clean and provides adequate protection against freezing helps to prevent expensive repairs and ensures proper operation during inclement weather.  Maintaining the correct pH level in your cooling system helps to prevent corrosion that can damage the sealing surfaces of your engine's head gaskets.
  • Inspect hoses for leaks and wear.  Inspect all belts for cracks.  Cold weather can cause hoses and belts to deteriorate more rapidly.
  • Check all fluids and top off as needed.  Inspect fluid reservoirs for cracks and leaks.
  • Inspect tires and brakes to make sure they are safe for winter driving.
  • Inspect windshield wiper blades.  Worn out wiper blades decrease visibility.
  • Check heater operation.
  • Check your external lighting, including headlights and brake lights.

Scheduled maintenance procedures are critically important to the mechanical stability of the modern automobile.  These procedures are outlined for each vehicle in your owner's manual, which is typically located in your vehicle's glovebox.

30k, 60k, and 90k maintenance procedures, if properly completed, will save you money by minimizing unexpected and expensive mechanical breakdowns.  A timing belt for example, if left unattended beyond the suggested replacement interval, can cause severe engine damage when it breaks.  Remember, simple and inexpensive maintenance is far less expensive than replacing an engine, transmission, or major electrical components.

Approximately every 3,000 miles, we suggest checking the following key areas:

​Every 30,000 miles:

  • Cooling system flush
  • Transmission flush
  • Transfer case service and flush (4x4 and AWD vehicles only)
  • Differential service
  • Brake fluid flush
  • Power steering system flush
