Keep your cool, without global warming. A proactive car air conditioning approach to protecting our environment.  As Australia begins phasing down HFC use (from January 2018), many new vehicle manufacturers may be switching to new air conditioning systems using the more environmentally friendly refrigerant R-1234yf, instead of R-134a. The benefits of using R-1234yf "Twelve Thirty Four", as R-1234yf is sometimes known, is an HFO type refrigerant delivering high performance, resulting in a more efficient air-conditioning system, fewer emissions and reduced fuel consumption. Hydrofluoroolefins (HFO's) have a double carbon bond meaning they trap less heat in the atmosphere than Hydrofluorocarbons (HFC's) and break down faster. Importantly, R-1234yf systems are specifically engineered to prevent refrigerant leakage and loss, including into the interior of the vehicle. The leakage of refrigerants contributes considerably to greenhouse gases. Why the switch? Older type refrigerants accumulate in the upper atmosphere as greenhouse gases and contribute significantly to Global Warming for a considerable time. In the mid-'90s, the old R-12 (or Freon), which takes a long time to break down into a non-greenhouse gas, was replaced with R134a, which breaks down much quicker. R-1234yf takes that improvement to the next level, breaking down in less than half the time of R-134a (and a fraction of the time R-12 can take). R-134a will remain in use for some time and a licensed mechanic can still service R-134a air con systems, but new vehicles will likely use the new systems with R-1234yf. Some already are. Irrespective of what type of refrigerant your car air conditioner uses, a car service workshop undertaking air conditioner service must have the right knowledge and equipment to handle these gases responsibly. You should always take your car to a mechanic with the skills and specialist equipment to undertake air conditioning service safely and correctly.

Understanding Hydraulic Hoses Before delving into the exceptional services offered by D & D Mechanical & 4WD, let's briefly explore the importance of hydraulic hoses and their essential role in heavy machinery serving a variety of purposes due to their flexibility and ability to withstand high pressure. Here are some of the key uses: Power Transmission: Hydraulic hoses are crucial in transmitting power to different parts of the machinery. They convey hydraulic fluid, which generates the force needed to operate the equipment's moving parts. Actuation of Cylinders: These hoses are used to transfer fluid to hydraulic cylinders, which then extend or retract to perform tasks like lifting, digging, or pressing. Cooling Systems: In some machinery, hydraulic hoses are used in cooling systems to transfer coolant to various parts, helping to maintain optimal operating temperatures and prevent overheating. Lubrication: They can also be employed in lubrication systems to deliver oils and lubricants to parts that require smooth and efficient movement, reducing wear and tear. Flexible Connections: Due to their flexibility, hydraulic hoses allow for movement and vibration in machinery without causing damage, making them suitable for connecting moving parts. Pressure Absorption: Hydraulic hoses are designed to absorb and dampen pressure spikes in hydraulic systems, which protects components from damage and ensures smooth operation. Remote Operation: In scenarios where control systems are located at a distance from the machinery, hydraulic hoses provide the means to remotely operate equipment safely and efficiently.

Modern radiator coolants not only protect your car from overheating, or the fluid from freezing, they also protect the radiator system from corrosion. D & D Mechanical & 4WD in Goolwa are very knowledgeable and experienced in looking after these systems.  It is recommended that you exchange your radiator coolant fluid every two years or 40,000 km's whichever comes first. However the size of the engine, the climate in your area, the age of your current coolant, and the total miles that have been driven can all affect the need to replace the coolant in your radiator. Knowing when to replenish your radiator fluid isn't always easy - obviously, when it has gone a dirty brown colour it's a sign it probably needs to be flushed and replaced - however even fresh-looking coolant could have lost its corrosion protection properties and without measuring its reserve alkalinity there's no signal that it is no longer protecting your vehicle components, and it could even be doing more damage than good. Maintaining good coolant means your radiator system will be much better protected from corrosion and will have a longer life span, it will help prevent you from having to replace expensive engine components. At D & D Mechanical & 4WD in Goolwa at your request, we will perform a full 65 Point Vehicle Inspection report for free as part of any minor, major or log book service. Part of this inspection includes checking the level and condition of coolant in your system and the written report will advise you if we feel a radiator flush, fluid replacement or any repairs are required to maintain the performance of your vehicle.

Even if it looks clean, your coolant still might need replacing!

Faulty and low charge batteries are to be avoided. Don't wait till you're stranded somewhere on the side of the road, hoping for a jump start. It is easy to have your car, bike, truck battery tested or charged up at D & D Mechanical & 4WD in Goolwa.  Often issues occur because we have all reduced how much we drive or decided to only rely on one car (as petrol prices skyrocket!) and have left the other in the garage. But did you know that batteries can still discharge even when your car isn't in use? - ask D & D Mechanical & 4WD about a battery test today!  Our technicians do a battery load test as part of the 65 Point Vehicle Inspection Report that comes free with every car service. If you have concerns, we can do a stand-alone battery test and inspection right here in Goolwa. Car Battery FAQ How do I know if my battery is getting flat or low? The most obvious sign of a flat battery is when your car won't start, but modern motor vehicles can show symptoms like non-essential functions not operating correctly - things like idle stop-start function not working, or the car's air-conditioning not working effectively.
Other signs you might need a new car battery include: Vehicle is slow to start Engine won't start Dash Lights work, but engine won't start Constantly needing a jump start Film or corrosion on the battery Cracked swollen or leaky battery Rotten egg smell under the hood Do I need a new car battery? The most obvious sign of a flat battery is when your car won't start. Modern motor vehicles can show symptoms like the idle stop-start not working or the car's air-conditioning not working to full capacity.

Other signs include cracked, dirty or leaky batteries, a rotten egg smell under the hood of your car, or regularly needing a jump start or recharge. The best way to know if you need a new battery is to get a car battery test at {{{businessName}}} Does a flat battery use more fuel? Yes! When your car battery is running flat, the alternator works harder to recharge the battery. This added load on the engine means it burns more fuel. Where can I buy a new car battery? Come in and see us! As a Repco Authorised Service Centre, {{{businessName}}} have access to the highest quality batteries to suit most vehicles. Who can test my car battery? {{{businessName}}} can do a battery load test. Phone us or visit the workshop today. Why choose {{{businessName}}} for a battery test? If you have concerns about your vehicle's performance, it is wise to get your battery tested at a full-service workshop like {{{businessName}}} rather than at a parts store. That's because we take into consideration the whole vehicle and can diagnose any deeper issues. There is nothing worse than replacing your car battery only to find the problem actually lies elsewhere… except maybe being told your battery test is fine with no explanation for your ongoing issues! Can my car battery be recharged? Yes, in fact the battery is being recharged by the alternator in your car whenever the engine is running. Sometimes this fix isn't enough, and your battery requires an external recharge. It's best to ask the professionals like our team at {{{businessName}}} about this, as you could void the battery warranty by recharging it yourself. Sometimes external recharging is not the best option because every battery eventually reaches a point in its life where replacement is the only answer to avoid unexpected breakdowns. Can I fit my battery myself? The short answer is yes...But! Modern vehicles are “computers on wheels”, so if you decide to DIY you must follow proper installation procedures to avoid damaging the ECM (Engine Control Module) and TCM (Transmission Control Module). Plus, if the battery gets incorrectly installed, items like the radio, the navigation system and security codes may need to be professionally reset. Talk to {{{businessName}}} today. We can recommend the right battery for your needs and install it for you. 

Ever replaced your battery only to find your car problem wasn't fixed? Don't be left feeling flat, get your battery tested at a full service workshop.
