Do you drive an Automatic vehicle? Then you might not even know there is a clutch in your vehicle. But without it, the gears in your car will not change. Marks Mechanics in Garbutt know all about repairing and servicing these systems including clutches, cables and fluids. Learn more below. What is a clutch? The clutch is one of the most important elements of your vehicles driving operation. Your engine is what causes your wheels to spin, but what happens when your car needs to stop? The engine shouldn't stop spinning but the wheels need to. It's the clutch that allows this to happen. The clutch allows the transfer of power from the engine to the wheels to be interrupted while a gear is being changed or while the car is stationary and the engine continues to run. What is clutch fluid? Some vehicles have hydraulic clutches - when you press the clutch pedal, the clutch fluid moves the pressure from the pedal through to the clutch and disengages the power transmission. Leaking clutch fluid can cause all kinds of problem in your vehicle so it is very important to monitor it regularly. At Marks Mechanics in Garbutt we check your clutch fluid, hydraulic system or clutch cables for you in the course of our free 65 Point Vehicle Inspection - which you can request as part of every car service.
 What signs to look for if your clutch is not performing You should have your clutch looked at if: You notice a burnt ‘toast' or ‘burning rubber' smell in your car, or smoke from under vehicle Your vehicle is slipping out of gear for no reason There is jerky or sticky gear operation Your clutch is not disengaging fully, or your clutch is sticking or shuddering If your clutch is showing any of the problems above - it could mean any number of faults. Clutch problems are difficult to diagnose by symptoms alone because many issues cause the same symptoms, depending on the vehicle and type of engine. The best way to deal with clutch shuddering, slipping or noise is contact us at Marks Mechanics today. We can perform clutch service and repairs on most makes and models right here in our Garbutt workshop.

At Marks Mechanics in Townsville, they specialise in breathing new life into vehicles, ensuring they drive as smoothly as the day they rolled off the production line. One of their remarkable success stories involved a BMW E92 struggling with persistent engine misfire issues. Through a meticulous process known as walnut blasting, Marks Mechanics effectively restored the vehicle's performance, offering the engine a fresh lease on life and returning it to peak driving condition. Understanding Carbon Deposition To comprehend the significance of walnut blasting, it's essential to understand the villain in this narrative: carbon deposition. When a car’s fuel doesn’t burn completely, it leaves behind hydrocarbon olefin residues. These residues cling to the engine intake, valves, and cylinder pistons. Over time and under high-temperature conditions, these residues transform into hard black shells known as carbon deposits. This is where the magic of walnut blasting comes into play, a service that Marks Mechanics has perfected over the years. The Importance of Cleaning Carbon Deposition Why is it so crucial to tackle carbon buildup? These deposits can disrupt the delicate air-fuel ratio, resulting in diminished engine power, increased fuel consumption, and in some instances, prevent the valves from seating properly. This can lead to engine misfires or cause the car to shake intermittently when idling. Regular cleaning every 40,000–50,000 kilometres is pivotal in maintaining the engine's performance, and this is exactly what Marks Mechanics advocates for its clients. Why Walnut Shells Are the Preferred Choice You might wonder why walnut shells are the chosen medium for this procedure. It's simple: they're gentle on metal parts yet remarkably tough on carbon deposits. This makes them ideal for engine cleaning without risking damage to the engine components. Many automobile manufacturers even recommend walnut blasting as the "official" method for carbon deposit removal, a testament to its efficacy and safety.

Marks Mechanics employs state-of-the-art equipment for walnut blasting, ensuring precision and effectiveness. Their advanced tools guarantee thorough cleaning, restoring the engine's optimal condition without any risk of damage. A Look at the Vehicles Serviced Beyond BMWs, Marks Mechanics has honed their expertise by servicing a wide range of vehicle brands with walnut blasting, including Audi, Mercedes-Benz, Volkswagen, Toyota, Ford, Nissan, Mazda and many more. Their commitment to excellence ensures that no matter the vehicle, it receives the highest standard of care and attention. With their deep understanding of engines and commitment to quality service, Marks Mechanics in Townsville stands out as a leader in vehicle maintenance and performance restoration. They invite all vehicle owners in the area to experience the benefits of walnut blasting and keep their engines running smoothly. For anyone seeking to restore their vehicle to its prime, Marks Mechanics is the place to go.
