What we work on

Every job starts with a real diagnosis, not a guess. If you don't see your service listed, call — we likely cover it.

Diagnostics & check engine lights

Dash light on? We hook up OBD-II scanning to read the actual fault codes, then verify the root cause by hand before recommending any repair. No guessing — just a clear, honest read on what's actually wrong.

Routine maintenance & oil changes

Oil and filter changes, fluid flushes, belt and hose inspections, tire rotations, and manufacturer-recommended service intervals that keep your warranty intact and your engine running its full lifespan.

Wheel alignment

Pulling to one side, uneven tire wear, or a steering wheel that's off-center? We align all four wheels to manufacturer spec so your car tracks straight, your tires last longer, and your steering feels right.

Brakes & suspension

Soft pedal, grinding noise, or a car pulling to one side — we inspect pads, rotors, calipers, and the full suspension system, then replace only what's worn past spec. Every brake job is road-tested before handoff.

Engine & transmission

Timing belt replacement, transmission fluid services, and clutch work — the systems that determine whether your vehicle lasts another five years or starts costing more than it's worth.

Electrical & battery

Battery testing, alternator and starter repair, and wiring diagnostics for the issues that don't always throw a clean code — the kind of troubleshooting that takes real diagnostic patience.

Air conditioner repair & heating

Common questions

Before you call

Do you work on all makes and models?

Yes — domestic, import, and most hybrid vehicles. Give us a call first if you have something especially specialized.

Do I need an appointment?

Appointments get priority, but we take walk-ins for diagnostics and quick maintenance when the bay allows.

Will you call before doing extra work?

Always. You get a written estimate up front — nothing gets touched beyond that without your sign-off.

What's covered under your warranty?

Most repairs are backed by a 12-month / 12,000-mile warranty on parts and labor.

Not sure which service you need?
