Monroe’s Trusted Auto Repair Shop

FS Autoworx has been a family-owned shop serving Monroe, WA, and Snohomish County since 2020. We handle domestic, import, European, and diesel vehicles—from oil changes to full engine rebuilds—with 75+ years of hands-on experience.

Every Vehicle Type, One Trusted Shop

Domestic Trucks and Cars

Ford, Chevy, GMC, Dodge, and Chrysler vehicles are the backbone of Snohomish County. We know these platforms well—gas and diesel, older body styles, and current model years.

Import and Asian Vehicles

Toyota, Honda, Nissan, Subaru, Mazda, Hyundai, and Kia owners are all welcome here. We service imported makes across the full range of maintenance and repair needs.

European Makes

BMW, Mercedes-Benz, Audi, Volkswagen, and Volvo vehicles require attention to manufacturer specifications. We have the diagnostic tools and experience to work on European platforms correctly.

Diesel Engines

Diesel is our specialty. From Cummins and Powerstroke to Duramax and smaller import diesel engines, we have 75+ years of diesel-specific diagnostic and repair experience backing every job.

From check engine lights to complete engine rebuilds, we diagnose accurately and repair with precision.

Transmission Service

Fluid changes, inspections, and full transmission repairs for automatic and manual gearboxes across all makes.

Electrical and Diagnostics
