Businesses listed under Engines typically supply, repair, rebuild or service engines and related components. Their work may cover petrol and diesel engines for cars, vans, motorcycles, boats, agricultural machinery, generators and other equipment. Some specialise in particular engine types or applications, while others handle a range of makes and sizes. Services can include fault diagnosis, servicing, removal and refitting, machining, reconditioning and complete engine rebuilds. Work may involve inspecting and replacing worn parts such as pistons, bearings, valves, seals and timing components, as well as testing an engine after repairs. Suppliers may offer new, used or reconditioned engines, along with components and accessories. The exact services available vary, so customers commonly need to provide the engine type, vehicle or equipment details and information about the fault or work required.
