Engine Diagnostics

Engine Diagnostics

We have exceptional diagnostic capabilities at Automotive Authorities. Not only do we use the latest technology and state-of-the-art equipment, our technicians review areas of your vehicle’s engine that may not be covered by a computer system. If your check engine light is on, we’ll find out why and make sure your running conditions are safe and sound.

Engine Repair

Engine Repair

Complete engine service and repair can be anything from a replacement remanufactured engine to a leak repair to a new timing belt to manufacturer’s mile interval services. Our mechanics can appropriately handle any engine issue, including diesel engine repairs on Ford Powerstroke, Dodge Cummins, and Chevy Duramax.

Brake Service

Brake Service

Not being able to stop is one of the worst things that can happen on the road. Brakes wear out and need to be serviced and replaced on a regular basis for optimum safety and performance. Our knowledgeable technicians understand the driving conditions in the Longmont area, and we know that your brakes require care—which is why we provide a complimentary inspection with every service to ensure that any issue is fixed before it becomes a dangerous problem.

Most vehicle manufacturers recommend recharging your air conditioning service every two years to keep it performing optimally. At Automotive Authorities, we offer complete A/C repair and recharge services, ensuring your air conditioning system has a long and trouble-free life.

Timing Belts

Timing Belts

Timing belts have a significant role to play in your car’s engine. They keep everything moving at the right time, ensuring your engine gets what it needs, when it needs it. A worn timing belt can damage your vehicle’s engine, so don’t hesitate to come by if you’re due for maintenance.
