Vehicles are usually described as 5 speed or 6 speed, meaning they have that many gear ratios. Those gears let the vehicle travel across the full range of speeds and use the engine's power efficiently. Transmissions are complex and are in constant use, so they take a lot of wear and tear. Many owners also forget to check and change the fluid on a regular schedule. That is why transmission problems are so common. At On Site Auto Repair in Santa Rosa, our transmission technicians can diagnose, repair, or replace your transmission. If you are looking for an honest transmission repair shop, give us a call today.
There are several warning signs that your vehicle can give you before your brakes may reach the point of potential failure or extensive repair. Whether composed of ceramic, semi-metallic, or organic materials, brake pads erode each time you depress the brake pedal. If the pads wear down too much without being replaced, the metal housing for the pads will make contact with the metal rotors (or drums), which may produce not only a safety issue but a situation where the rotors/drums are required to be replaced as a result of the prolonged contact of metal parts without the pad buffer. If you are in need of an affordable brake repair mechanic in Santa Rosa, please do not hesitate to schedule an appointment today!
Vehicle Inspection In Santa Rosa
The key to top notch automotive repair and troubleshooting lies in a thorough understanding of what’s actually going on under the hood. Sure, you know that a radiator keeps your engine cool, but understanding how it keeps it cool is the key to solving technical problems efficiently. If you know which parts perform what function, your powers of diagnosis will be much more powerful.
Radiator Inspection Service In Santa Rosa
Ensuring that your vehicle’s engine cooling system is in proper operating condition is extremely essential to engine life and performance. Operating at excessive temperatures can lead to premature engine wear. Your vehicle’s engine cooling system should be checked periodically, and a radiator coolant flush is also recommended to prohibit radiator corrosion. On Site Auto Repair will thoroughly drain and power flush the old coolant and particulates, and refill the cooling system with your vehicle manufacturer’s recommended coolant.

Auto Repair Services We Offer in Santa Rosa, CA
Our shop at 363 W 9th St B & C handles a wide range of repairs and maintenance for drivers across Santa Rosa and Sonoma County.
Engine Diagnostics and Check Engine Light
A check engine light means your car is reporting a fault. We connect an OBD-II scanner, read the fault codes, and explain what they mean in plain language. We diagnose the problem first, then tell you what the repair will cost.
Oil Change Service
We do full-synthetic and conventional oil changes. We use the viscosity grade your manufacturer specifies, such as 5W-30, 5W-20, or 0W-20, and we replace the oil filter every time.
Brake Repair and Replacement
Worn brake pads squeak. Worn rotors grind. A soft brake pedal is a warning. We inspect and replace brake pads, rotors, and calipers using OEM-quality and aftermarket parts, depending on your budget.
Battery, Alternator, and Starter Repair
We test your battery with a load tester, not just a voltage check. We also test the alternator and starter, because a failing alternator will kill a new battery quickly.
AC and Heating Repair
If your AC is not blowing cold, we recharge the refrigerant and check for leaks. If your heat is not working, we diagnose the cause and repair it.
Scheduled Maintenance and Tune-Ups
We handle spark plug replacement, belt inspection and replacement, air and cabin filter replacement, fuel system service, coolant flushes, and transmission fluid service. If you are not sure what your car is due for, we look it up by make, model, and mileage.
Tire Rotation and Inspection
Uneven tire wear affects handling, fuel economy, and tire life. We rotate your tires, measure tread depth, inspect the sidewalls, and check the pressure.
Pre-Purchase Inspection
Thinking about buying a used car? We check the brakes, belts, fluids, undercarriage, and suspension, and we run a diagnostic scan for hidden fault codes. Call for current pricing.
