What We Handle
Oil Change
We drain old oil, replace your filter, and refill with the manufacturer-recommended grade for your specific make and model. Takes about 30 minutes, and we'll show you the old filter if it's revealing anything about your engine's condition.
Learn moreBrake Repair
We inspect pads, rotors, calipers, and brake lines to determine what's causing noise, vibration, or reduced stopping power. Our shop uses a hydraulic brake lathe to resurface rotors on-site when replacement isn't necessary yet.
Learn moreEngine Diagnostics
We plug into your vehicle's computer system and interpret the actual fault codes causing your check engine light. Our Snap-on diagnostic scanner reads manufacturer-specific codes that generic readers miss, especially on European and Asian imports.
Learn moreTransmission Repair
We diagnose slipping gears, delayed engagement, and fluid leaks through pressure testing and electronic analysis. Angel has rebuilt transmissions on everything from Honda Civics to Ford F-250s over three decades.
Learn moreTire Service
We mount, balance, rotate, and repair tires using a Hunter road-force balancer that measures how the tire and wheel work together. This equipment catches vibration issues that standard balancers can't detect.
Learn moreAC Repair
We test system pressure, check for refrigerant leaks with UV dye, and verify compressor operation. Our Robinair recovery machine handles both R-134a and newer R-1234yf refrigerants required in post-2017 vehicles.
