Auto mechanics perform routine maintenance and extensive repair on cars, trucks and sport utility vehicles (SUVs). They must be familiar with a wide variety of vehicle systems to diagnose problems, replace components and ensure that a vehicle is safe to drive. Auto mechanics make use of many different types of tools, ranging from simple to high tech.
Wrenches and Sockets
The base of an auto mechanic's tool kit consists of wrenches and sockets. These tools are necessary for removing fasteners to gain access to different parts of the vehicle, both in the interior and under the hood. Mechanics need sockets with both English and metric measurements for use with both import and domestic cars. They also use specialty versions of common hand tools like oil filter wrenches, torque wrenches and Allen wrenches to remove specific components.
Brake Tools
Auto mechanics use a series of specialty tools for servicing car brakes. Brake spring pliers are useful for disengaging the small springs that engage inside a brake assembly. Mechanics may also use vice grips to grasp the small components within the brake assembly. Brake dust and brake fluid are both hazardous, so mechanics use special cleaning products to remove residue and basic safety items like gloves and eye protection to stay safe.
Electrical Tools
Automotive electrical systems are complex networks of wires, motors, switches and computers. To diagnose and repair electrical problems, auto mechanics use tools like a multimeter, which detects amperage and voltage, as well as 12 volt circuit testers and test probes that pierce wire insulation. Wires, wire cutters and electrical tape are also tools of the trade for rewiring electrical accessories.
Large Tools
Auto mechanics make use of some large-scale tools that perform special functions in certain repairs. Frame machines are the size of a car and attach to the vehicle's underbody to bend the frame back into shape following an accident. Engine hoists, which may be mechanical or hydraulic, lift the engine out of a car using chains and pulleys for mechanical advantage. Lifts can raise even the heaviest car or truck so technicians can work more freely on wheels, exhaust systems and gas tanks. Mechanics also use welding torches to repair and fabricate vehicle frames and exhaust systems.
Computers
Computers are an essential tool for auto mechanics who work with newer cars. Many of the vehicles on the road today use advanced engine control units to manage performance and diagnose problems. A mechanic with the proper equipment can tap into the on-board computer memory to identify and irregularities or error codes that might indicate where the problem originated.
