Which Repair Services Does M&M Auto Techs Provide?  

Our service menu covers the full spectrum of what your vehicle needs to stay safe, reliable, and efficient on Southern California roads. Brake repair is one of our most requested services. Our technicians inspect every component of your braking system, including brake pads, rotors, calipers, brake lines, brake fluid, and the ABS, to ensure your stopping power is never compromised. We also perform engine diagnostics using advanced computerized scanning tools that read fault codes and live sensor data, giving us an accurate picture of what is happening inside your engine before we recommend any repairs. Cooling system repair is another area where we excel, addressing issues with the radiator, water pump, thermostat, coolant hoses, and heater core that can lead to overheating if left unresolved. For vehicles approaching higher mileage, timing belt replacement is a critical service we perform with precision, replacing not only the belt itself but also the tensioner, idler pulleys, and often the water pump in the same visit to protect your engine from costly internal damage. Suspension repair rounds out our mechanical offerings, with our team inspecting and replacing shocks, struts, control arms, ball joints, tie rods, sway bar links, and bushings to restore the smooth, stable ride your vehicle was designed to deliver.  

How We Handle Electrical and Climate System Repairs 

Electrical and climate-related issues can be some of the most frustrating problems a driver faces, largely because the symptoms are not always obvious until the problem becomes serious. Our technicians are experienced in alternator repair, diagnosing failures in the rotor and stator assemblies, voltage regulators, alternator bearings, and pulley and belt systems that keep your charging system functioning properly. A failing alternator often goes hand in hand with battery trouble, so we also specialize in car battery replacement, evaluating cold cranking amps, battery voltage, and terminal condition to match your vehicle with the right AGM or standard battery for its demands. When the summer heat in San Bernardino makes your commute unbearable, our car A/C repair service addresses the full system, including the compressor, condenser, evaporator, expansion valve, refrigerant levels, and blower motor, to restore cool, comfortable airflow to your cabin. We use both R-134a and R-1234yf refrigerants depending on your vehicle’s specifications, and we perform leak detection to ensure the repair lasts. Whether you are searching for general auto repair near me or need a specific system diagnosed and repaired, M&M Auto Techs has the expertise, the equipment, and the commitment to get you back on the road right.
