Reliable Auto Repair & Diagnostics Serving Folsom, CA

Our diagnostic process starts with a professional-grade OBD-II scan that reads all stored and pending fault codes across every module in your vehicle. From there our technicians perform pinpoint sensor testing — checking live data streams, voltage drops, and circuit continuity — to isolate the root cause rather than guessing at parts. We also do a visual inspection of related components like hoses, belts, wiring harnesses, and connectors. Before we recommend any repair we walk you through what we found and why it matters, in plain language.

Most repairs at 916 Auto Repair are priced using labor-guide flat rates, which means you pay for the job, not the clock. For common services like starter or alternator replacement, cooling system repairs, and AC recharge you can expect an average ticket in the $350–$900 range depending on parts. More involved work such as head gaskets, timing components, or full AC compressor replacement typically runs $900–$1,800. We always provide a written estimate before any work begins and are transparent about parts markup — no surprises at pickup.

Yes. For common mechanical issues — starters, alternators, water pumps, serpentine belts, cooling hoses, and basic AC recharges — we typically complete same-day repairs when you drop off in the morning. Morning drop-offs get prioritized scheduling and our diagnostic results are usually ready within two hours so you can make an informed decision quickly. If parts need to be ordered we will tell you immediately and give you a realistic completion timeline.

Absolutely. Warm air from your AC is one of the most common complaints we see from Folsom drivers every summer. We start with a UV dye leak detection to find any refrigerant leaks in the lines, fittings, condenser, or evaporator. If the compressor has seized or the condenser is damaged from road debris we handle full component replacement. Once any leaks are addressed we evacuate the system and recharge it to factory spec refrigerant levels. Most AC repairs are completed same day.

The check engine light can trigger for dozens of reasons ranging from a loose gas cap to a failing catalytic converter or misfiring cylinder. Common causes we see include emissions system faults (O2 sensor, EVAP system, catalytic efficiency codes), sensor malfunctions (MAF, MAP, throttle position), and mechanical wear triggers like misfires from worn spark plugs or coils. The only way to know for certain is a proper diagnostic — not a free code read at an auto parts store, which only tells you the code, not the cause.

We invest in the same professional-grade diagnostic equipment used at dealerships — factory-level scan tools, oscilloscopes for electrical diagnosis, and A/C manifold gauges for precise refrigerant work. Unlike chain shops where technicians are incentivized to upsell, our certified mechanics are paid to fix your car correctly the first time. We have been serving the Gold River and Folsom corridor for years and our reputation in the local community is our most important asset.

Yes. All mechanical repairs at 916 Auto Repair come with a standard parts and labor guarantee. If a covered repair fails within the warranty period we will make it right at no additional cost. We use quality parts from reputable suppliers and stand behind our work. Ask our service advisor for specific warranty terms on your repair at the time of your estimate.

Dealerships charge premium labor rates — often $175–$225 per hour — and apply their corporate pricing model to every job regardless of complexity. At 916 Auto Repair our labor rates are significantly lower while our diagnostic capability is equivalent. You also get direct communication with the technician working on your car, not a service writer acting as a go-between. We do not upsell services your car does not need and we will show you what we found, not just tell you about it.
