Mechanical repairs we carry out in Rumney
A mechanical repair covers any fault in the moving, load-bearing or drivetrain parts of a car or van, and drivers who come to our Rumney workshop often need more than one of them looked at in the same visit. Every repair is carried out in house at Wentloog Road, with no subcontracting.
- Engine faults: misfires, loss of power, overheating and oil leaks, starting with engine diagnostics so the fault is confirmed before anything is quoted.
- Brakes: pads, discs, calipers, master cylinders, hoses and pipes. See our brake repair service.
- Clutch and gearbox: clutch kits, dual-mass flywheels and hydraulic faults. See clutch replacement.
- Suspension and steering: shock absorbers, control arms, drop links, track rods, wheel bearings and ball joints. See suspension repairs.
- Exhausts: manifolds, mid sections, rear boxes, catalytic converters and lambda sensors. See exhaust repairs.
- Cooling system: water pumps, thermostats, radiators and pressure testing.
- Timing belts and chains: replaced at the manufacturer interval to protect the engine. See cambelt replacement and wet belt replacement.
How every repair is handled
- The fault is diagnosed before a quote is given, not guessed from a symptom.
- You get a written quote before work starts, and a phone call before anything is added.
- All repairs are carried out in our own workshop, with no subcontracting.
- Parts carry a manufacturer warranty and our labour is guaranteed.
How long do common repairs take?
Brake pads and discs usually take under two hours. A clutch replacement takes most of the working day. A timing belt replacement typically takes three to four hours, depending on the engine. Larger jobs such as engine rebuilds take longer, and we discuss the timescale when we quote so you are not told after the work has started.
How do I know my car needs a mechanic?
Unusual noises are usually the first sign: a knock over bumps, a squeal from the brakes, a rattle underneath or a change in how the car handles. Warning lights, smoke from the engine bay, vibration through the steering wheel or a car that pulls to one side are all reasons to book an inspection. Our guide on when you need a mechanic in Cardiff covers the signs in more detail, and our engine management light guide explains the most common warning light causes.
Cars and vans we repair
We repair cars from all the major manufacturers, including Ford, Vauxhall, Volkswagen, Audi, BMW, Toyota, Nissan, Honda, Kia, Hyundai, Peugeot, Renault, Skoda, Seat and Mercedes-Benz, along with vans such as the Ford Transit, Volkswagen Transporter, Mercedes Sprinter, Renault Trafic and Vauxhall Vivaro, and hybrid models. If your car has failed its MOT on mechanical grounds, we repair it and retest it on site.
