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. Col Harrison Automotive in West Ryde 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 Col Harrison Automotive in West Ryde 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 Col Harrison Automotive today. We can perform clutch service and repairs on most makes and models right here in our West Ryde workshop.

Col Harrison Automotive (AU10851) can perform all your Automotive Air Conditioner Regas, Repairs, Inspection or Servicing needs in West Ryde and the surrounding areas. Modern cars are complex and just like the engine your vehicle's air conditioner system has components that need to be serviced or replaced on a regular basis to ensure continued reliable and efficient operation. Leaking refrigerant or low refrigerant due to evaporation means your air con system will begin to deteriorate and will have to work harder, which means you burn more fuel. Therefore it is important to study the condition of the rubber seals at regular intervals for any signs of leaks or fractures which could indicate a loss of refrigerant. A yearly car air conditioning service means you can assist prevention of costly breakdowns now and in the future, keep passengers safe by helping to prevent the build-up of potentially harmful substances and a well serviced automotive air conditioning system actually saves you money because it reduces your overall fuel usage. Col Harrison Automotive care about the environment and have Arctick Authorisation (AU10851) to reliably and responsibly conduct automotive air conditioning regas, repairs, inspection or servicing. Book your next car air conditioning service with the experts at Col Harrison Automotive in West Ryde today! Have questions about your car's air con? 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 Col Harrison 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 Col Harrison 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 Col Harrison 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.
