Brakes & Calipers - Spongy Brakes

If your brake pedal feels spongy, it is likely that there is air in the hydraulic system. It is the elasticity of the air that creates the mushy feel of the brake pedal. To remove the air, the system must be bled. Air usually enters the system either via a leak somewhere along the brake system's...

Electrical Systems - All Charged Up

Radiator & Cooling Systems - Not So Cool(ant)

When an automobile's radiator leaks, it may be that the coolant has not been changed according to the recommended schedule and has become corrosive. Coolant leaks may also stem from normal vibration that has led to separation between parts connected by solder, epoxy, or mechanical crimps...

Suspension Systems - Ties that Bind

Tie rods are suspension components that relay force from the steering center link or the rack gear to the steering knuckle, which enables the wheels to turn. When this component becomes worn or loose, it causes a feathered wear pattern on the tires. One simple and effective way to detect worn ...

Kevin and Rick are always easy going and great guys to do business with. They have pointed out a couple things going bad on my car and didn't pressure me into replacing right away. Instead they gave me a time-line.

Kovach's was wonderful. They looked at my car within 10 minutes, let me know what the source of the leak was, and helped me make an informed decision regarding repair. Better yet, they didn't charge me to inspect it.
