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. GMR Automotive in Caboolture 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 GMR Automotive in Caboolture 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 GMR Automotive today. We can perform clutch service and repairs on most makes and models right here in our Caboolture workshop.

Your car needs to have clean Brake Fluid. Clean brake fluid not only protects your safety it also prolongs the life of your braking system components by preventing corrosion. Your car's Brake Fluid needs to be kept clean and free of moisture in order to maximize braking efficiency, as well as prevent corrosion of your brake system components that could lead to complete brake failure. GMR Automotive offers comprehensive brake services and repairs that use quality parts, all backed by our nationwide warranty. How much does brake system flush cost? The cost of a brake fluid flush depends on the vehicle type and any other additional parts, repairs or maintenance that might be needed. During the process, we'll also take the wheels off to check the calipers, wheel cylinders, brake hoses, brake lines, and master cylinder for any potential issues or signs of wear and inform you of any problems we find. If you'd like to get an estimate, just give our friendly staff a call to discuss your car. What is the brake flush procedure? The brake flush procedure starts by raising the car up and taking the wheels off. Then, we remove the present fluid from the master cylinder and replace it with fresh, quality brake fluid of the right type. We will then 'bleed' each brake and the clean fluid will flush through the system, completely replacing the old. We will also examine the other components of the brake system for any signs of damage or wear that require attention. A brake fluid flush may be done as part of a routine service, but we may also recommend it outside of a regular schedule if necessary. My brake fluid looks fine to me - why tell me it needs a flush? Checking the colour of the brake fluid can be helpful, but don't rely on it alone - even if it looks clean, it might still contain a dangerous amount of water that could lead to boiling and consequent loss of braking pressure or even sudden brake failure. In this case, only a professional boiling point test can tell you the true condition of your brake fluid. How often should brake fluid be flushed? It is generally suggested to change the brake fluid every two years, however, it's best to check the condition of your brake fluid regularly. GMR Automotive can provide you with a full 65 Point Vehicle Inspection Report, with every full car service, to ensure your safety on the road. This report gives you detailed information on the condition of your brake fluid, master cylinder, front and back discs and pads, calipers and cylinders and more, letting you know if any repairs are needed, either now or in the near future. When it comes to brake safety - we don't stop - so you do when you need to.

Moisture can accumulate in the fluid which limits braking efficiency, increases the corrosion of brake system components and can cause total brake failure...

As the colder months approach, ensuring your vehicle remains reliable is more critical than ever. At GMR Automotive, we emphasise the importance of pre-winter battery check-ups to prevent any unforeseen breakdowns and to maintain your vehicle’s performance. The Impact of Cold Weather on Car Batteries It’s a well-known fact that cold weather can significantly impact the performance of your car battery. The lower temperatures reduce the battery's capacity to hold a charge, putting extra strain on it when starting the car. This can lead to a decreased lifespan and, in some cases, failure to start altogether. This is a concern for batteries that are over three years old, as their efficiency starts to diminish. Regular testing of these batteries ensures your vehicle starts through the colder months. Importance of Regular Battery Checks At GMR Automotive, we cannot stress enough the importance of regular battery checks, especially before the winter sets in. A battery that is over three years old is likely to have undergone some wear and tear, reducing its performance and reliability. By conducting regular checks, potential issues can be identified early on, preventing the inconvenience of being stranded due to battery failure.  Rest assured that if you have your car serviced by us, we will automatically include a Battery Test and visual inspection each time. If the battery doesn't' pass the test then we will advise you and with your approval install a new one. Quick Tests and Replacement If you're uncertain about your battery's condition, our experts at GMR Automotive can assist. We have the tools, such as a Battery Load tester, to quickly check your battery's health. If necessary, we can replace the battery to ensure your vehicle keeps running. With a range of high-quality Century batteries on hand, we can promptly replace your battery, minimising any inconvenience. So as the temperatures drop, don't let your car battery's health slide. At GMR Automotive, we are committed to ensuring your vehicle is winter-ready with reliable batteries. Contact us today to schedule your pre-winter battery check-up and stay ahead of the cold.

GMR Automotive (AU53313) specialises in taking care of your vehicle's air conditioning (AC) regas, repairs, service, and inspection requirements in and around Caboolture.  We acknowledge that modern vehicles are complex, comprising numerous elements that require regular upkeep to ensure they run optimally. Among these components, the car air conditioner is an often-overlooked yet crucial system that impacts the overall fuel efficiency of your vehicle. This article will discuss the importance of routine AC maintenance in optimising your fuel usage, how car ACs work, and how we at GMR Automotive can assist you. Regular Air Con Maintenance and Fuel Efficiency Like your car's engine, the AC system comprises multiple parts that require routine service or replacement for continuous and effective performance. When refrigerant pressure drops due to evaporation over time or leaks, your AC system's functionality starts deteriorating, and it must exert extra effort to perform. This extra work translates into increased fuel consumption. Typically, evaporative or leakage loss of refrigerant means your AC system will begin to wear and work harder, leading to higher fuel usage. It is, therefore, crucial to routinely inspect the condition of rubber seals for leak or fracture signs indicating refrigerant loss. Conducting an annual car AC service can prevent expensive system breakdowns now and later. A properly serviced AC system ensures passengers' safety by protecting them from toxic substances, prevents overheating, and reduces fuel consumption. Here at GMR Automotive, we value environmental conservation, so we offer licensed car AC regas, repairs, service, and inspection by professional technicians. The Functioning of Car Air Conditioners A car air conditioner system is comprised of four critical components, each playing a unique role in cooling the interior of your car. The basic functionality of a car's air conditioner is to extract heat from the air inside your vehicle and displace it outdoors. This process leaves behind 'conditioned' or cooled air for recirculation. The hot interior air is channeled through a gas-filled evaporator, where the refrigerant (in gas form) absorbs the heat, effectively removing it from the car's air. The now heated gas goes through the compressor, where it gets additionally heated via compression. It is then propelled through the condenser, rapidly extracting the refrigerant's heat. Now transformed into a liquid, the refrigerant traverses the expansion device, either a TXV or Orifice tube, regulating its flow towards the evaporator. The high-pressure liquid turns into a low-pressure gas, and a fan blowing over the cold fins of the evaporator completes the process. GMR Automotive: Your Partner in Maintaining Car Air Conditioning Systems At GMR Automotive, we provide reliable and eco-friendly air conditioner maintenance and repair services for your car, ensuring an enjoyable driving experience and optimal fuel efficiency. Trust us to take care of your vehicle while keeping you and the environment safe. Air Conditioning questions answered How do air conditioners work? A car air conditioner system is composed of four essential parts : A belt-driven pump known as a compressor to compress and circulate gas. A radiator like unit called a condenser to redistribute heat and condense gas to a liquid. An expansion device, which could be a thermal expansion valve (TXV) or an orifice tube (subject to the kind of air-con system used). Some systems have an accumulator before the compressor to remove moisture from the refrigerant while TXV systems have a receiver-dryer before the evaporator performs the same crucial task. Both of these parts also store refrigerant. Car air conditioning is designed to pull the heat from the air within the car's interior area and transfer it outside, leaving only cooled or 'conditioned' air to be redistributed. Hot air is passed across a gas-filled evaporator, where the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car. The now heated gas is pulled through the compressor where it is further heated (via compression). The next stage involves the refrigerant being forced through the condenser to extract the refrigerant's heat quickly. The refrigerant, now condensed to a liquid, then moves through the expansion device (either a TXV or Orifice tube), which regulates the refrigerant's flow to the evaporator, changing the high-pressure liquid to a low-pressure mist (gas). A fan blowing over the evaporator's cold fins produces the cold air being blown into the car, and the entire process then begins all over again. Does the car air conditioner use more fuel? Yes! Your car air conditioning is using fuel. However, it's actually more fuel efficient to run car air conditioning than it is to have your windows down due to aerodynamic drag. If your air conditioning isn't performing its best, it may use more fuel to run. To avoid this, it's important that you have your air conditioning serviced regularly by professionals, like the ones at GMR Automotive.  What's the cause of the bad smell in car air conditioning? The damp environment can promote microbes, bacteria and even fungus growth inside the evaporator core. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Although modern evaporator units tend to be more efficient, they have more fins, meaning an increased capability to trap moisture and allow for micro-organism development. How do I know my car air conditioning is due for a service? If you cannot remember when your air conditioning was last serviced, perhaps it's time to book in with the team at GMR Automotive. You should also book in if: Your air conditioning system is blowing warm air There are damp patches or water stains under your dashboard Your car air conditioning system smells funny Your car air conditioning system is making strange noises There is weak air flow from the car air conditioning system Why does the car air conditioner need to be serviced? Car air conditioning is designed to pull the heat from the air within the interior area of the car outside, leaving only cooled or 'conditioned' air to be redistributed. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid. The compressor needs the right amount of oil in the refrigerant to prevent it from seizing up. Should the air filters be jammed with dirt and bacteria, it will affect the entire system's performance, and it can even cause it to stop working altogether. On top of inhibiting air conditioner efficiency, dirty air filters can cause health problems. Being exposed to the elements and very diverse operating conditions and being used intermittently rather than being 'Always On' can cause decay of the hoses, connections and seals. A vehicle air conditioning system should be examined regularly to ensure there are no problems or refrigerant loss due to failure or leakage from these points. Simply by cooling the air in your car under normal running conditions, the air filters get dirty and intermittent use can cause seals to dry and crack, allowing them to leak. Even without leaks, the gas in a car air conditioning system will eventually begin to degrade or evaporate over time. It should be recharged as required to keep the air con system in peak running condition. How often should a car air conditioner be serviced? Your automotive air conditioning system needs to be examined once a year for any signs of problems with the seals, hoses and connections and confirm there is no refrigerant reduction over time. Regularly servicing your automotive air conditioner system keeps refrigerant at optimum levels meaning the system does not need to work as hard. This, in turn, protects the system from damage and minimises fuel expenditure. Can I service my own car air conditioner? Only qualified mechanics with the appropriate training, like the ones at GMR Automotive, should attempt to service a car air conditioner. Specific licences are required to service or repair some types of car air conditioning systems, especially where re-gas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling certain refrigerants, which must always be fully recovered and not allowed to escape into the atmosphere during servicing. Refrigerant can also pose serious health risks if mishandled. Specialist equipment is also required as the air conditioning system is under extreme pressure and must be pulled into a deep vacuum to remove any moisture, to avoid seriously damaging the system. You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.
