Tire rotation refers to the regular practice of switching the position of each tire on the car.
Purpose: Tire rotation helps to equalize tread wear and is critical to gain the maximum life from your tire investment.

Maintenance Tips/Suggestions: Refer to your owner's manual for the recommended rotation interval and pattern; generally a rotation interval of 6,000 miles is recommended. The rotation pattern varies with different makes and models, which shows the tire locations during rotation. Some vehicles have different size tires on the front and back or directional tires. This limits the locations that a tire may take on the vehicle. When in doubt, check the owner's manual or consult a professional technician for guidance. Tire rotation time also offers a good opportunity to have the tires and wheels balanced. It's another step you can take to maximize your tire investment.

The primary function of your cars suspension and steering systems is to allow the wheels to move independently of the car, while keeping it "suspended" and stable. Any play or uncontrolled motion in these systems results in a deterioration of handling and accelerated tire wear. Vehicle alignment is closely tied to the condition of the suspension and steering systems.

Check the owner's manual to see if your driving habits are considered to be "severe service". This type of driving requires more frequent oil changes, warns the Car Care Council. Have the oil changed accordingly, usually every 3-5,000 miles.

For less wear and tear on the engine, drivers in cold climates (sub-zero driving temperatures) should drop their oil weight from 10-W30 to 5-W30. Your mom and dad would probably suggest simply moving to someplace warmer.

The engine cooling system affects your car’s overall dependability and engine longevity. Cooling systems have advanced over the years with new coolant formulations and new radiator designs and materials. If you suspect a problem with your cooling system, you should check it immediately.

What does it do? The key parts of the cooling system remove heat from the engine and automatic transmission and dissipate heat to the air outside. The water pump circulates coolant through the engine. The coolant absorbs heat and returns it to the radiator where heat is dissipated. The thermostat regulates the coolant temperature to keep it consistent for efficient engine operation.

A program designed to periodically check vehicle emissions to ensure they are within limits. Often referred to as an I/M (Inspection/Maintenance) program, they are used in numerous states and areas as required by the Environmental Protection Agency to improve air quality in those areas.

The axle on your vehicle is the structural component that connects two wheels together on opposite sites. It's a load-bearing assembly that acts like a central shaft, maintaining the position of the wheels relative to each other and to the vehicle body.

Our ASE certified technicians will inspect your engine's cooling system, record the condition, and compare to manufacturer's specs. Recommendations are made per the Motorist Assurance Program Uniform Inspection Guidelines.

The brake system is actually composed of two kinds of systems---Hydraulics and Friction Materials. Here's what happens within these systems between the time your foot hits the brake pedal and your car stops.
