At Westys Auto & 4WD, we pride ourselves on delivering top-tier mechanical repairs with a hands-on, honest approach. Specialising in all things 4WD and auto electrical, our workshop is where tough jobs get done right — the first time. Recently, a 4WD ute came into our shop showing signs of major engine trouble. Here’s a behind-the-scenes look at how our team tackled it. The Situation The customer reported: A noticeable loss in power Intermittent overheating Knocking noises coming from the engine bay After an initial assessment, we suspected internal engine issues — possibly a failed head gasket or deeper mechanical wear. The next step? Full engine inspection. Rolling Up Our Sleeves In the photo above, you’ll see two of our mechanics carefully removing the cylinder head. This is a critical part of diagnosing internal damage and is never rushed. This level of disassembly allows us to identify: Cracked or warped cylinder heads Valve damage or failure Excess carbon deposits Piston wear or scoring What We Found Upon removal, we discovered: Evidence of a blown head gasket Carbon build up around the valves Slight warping of the head (likely from repeated overheating) Luckily, the damage hadn’t reached the pistons — meaning a rebuild was viable without needing a full engine replacement. The Plan Going Forward We walked the customer through their options. Based on the findings and the customer's needs, we moved forward with: Head machining Gasket and seal replacement System flush and full reassembly Test drive and final diagnostics Every bolt was torqued to spec, and the engine now runs like a dream. Why It Matters At Westys Auto & 4WD, jobs like this reflect what we’re all about: Attention to detail Support for young tradespeople High-quality repairs built to last It’s more than just fixing cars — it’s about getting our customers back on the road with confidence.

Engine Diagnosis & Repair

A malfunctioning cooling system can quickly turn a pleasant drive into a stressful situation. Here at Westys Auto & 4WD, we understand the vital role a properly functioning cooling system plays in your vehicle's performance and longevity. As the leading experts in Rochester, we are committed to ensuring your engine stays cool and runs efficiently. Understanding the Vehicle Cooling System A vehicle's cooling system is like its personal air conditioner, keeping the engine at the perfect operating temperature. It consists of several components, including the radiator, water pump, thermostat, and hoses, all working together to circulate coolant and dissipate heat. As the engine operates, it generates heat, and without a functioning cooling system, this heat could lead to engine damage or even failure. Regular maintenance of your vehicle's cooling system is as essential as filling up your gas tank. At Westys Auto & 4WD, our professional mechanics have the expertise to perform thorough inspections, ensuring that every component is in top shape. A routine check can prevent overheating, prolong your engine's life, and save you from costly repairs down the road. Warning Signs of Cooling System Issues Being aware of the signs of a failing cooling system can save you from unexpected breakdowns. Keep an eye out for these warning signals: Rising temperature gauge Leaking coolant under your vehicle A sweet, antifreeze smell inside or outside your car Frequent need to top off the coolant Steam coming from the engine If you notice any of these symptoms, it's time to let the experts at Westys Auto & 4WD take a closer look.

Don't let the heat beat your engine!

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.

Modern radiator coolants not only protect your car from overheating, or the fluid from freezing, they also protect the radiator system from corrosion. Westys Auto & 4WD in Rochester 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 Westys Auto & 4WD in Rochester 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!
