Auto Care Services

We are the Premier Auto Repair Center of Merritt Island.


Maintaining the tire balance on your vehicle is critical to receiving satisfactory service from your tire investment. In addition to providing a smooth ride, we at 321 Auto know that balancing is a key component in tire wear.


Friction creates a substantial amount of heat which in turn causes rapid oxidation of brake fluid. Deposits and varnishes form in the brake system causing serious brake system malfunction. 321 Auto quickly and effectively removes oxidized and corrosive brake fluid, replacing it with new fluid.


The mission of 321 Auto is to deliver an accurate analysis and repair of your transmission problems through a combination of computerized diagnostic equipment and trained technicians working together.


321 Auto knows your vehicle's cooling system is extremely important. It’s what regulates the temperature in your engine and protects it from overheating, damage and breakdowns. The cooling system also keeps your engine from freezing during the winter months.

Computer-controlled anti-lock braking systems (ABS) are a recently developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is comprised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydraulics that pulse the brakes on and off rapidly, and the on-board computer.

For best results, consult your owner's manual, but consider that your driving probably constitutes a severe maintenance schedule. Usually, this means oil and filter changes every 3,000 miles or 3 months. If you change the filter yourself, dispose of it properly.

Take used filters to a facility that accepts them. Used filters can be crushed, removing the used oil and the steel part of the filter can be recycled. The oil from one used, seemingly innocent filter leaking into a landfill can taint 62,000 gallons of ground water.

  • Oil filter wrench
  • Oil drain pan
  • Funnel
  • Jack and jack stands or ramps
  • Oil filter


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.

Key Points

  • Check tire tread for wear
  • Replace tires when needed
  • Check air pressure in tire
