Used in internal combustion engines, Exhaust Gas Recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique which is used in both petrol and diesel engines. EGR recirculates a portion of an engine's exhaust gas back to the engine cylinders, diluting the oxygen in the incoming airstream and reducing peak in-cylinder temperatures.

Fitted to modern common rail diesels and petrol engines in order to meet Australian Design Rules (ADR's), the EGR system is a form of emission control designed to reduce emissions of harmful NOx gases into the environment.

NOx (or Nitrogen Oxide) is produced by an engine during the combustion cycle and is considered harmful to the environment. The EGR recirculates some of this NOx back through to the intake side of the engine to help maintain lower combustion chamber temperatures, minimising the amount of NOx emmitted.

As gases from the combustion cycle escape past the Piston Rings (called blow-by gases), they become trapped inside the crankcase, causing pressure to build up, promoting the builld up of sludge and shortening the life of the oil.

This pressure must be relieved and this objective is achieved via a process known as Positive Crankcase Ventilation through the PCV Valve. While necessary to avoid damage to seals and eventually the engine, this process also releases small amounts of engine oil back into the intake at the same time.

When the oil allowed through by a PCV Valve, turbocharger shaft or air compressor meets the recirculated NOx Gases within the Intake Manifold it becomes a problem. When mixed, a build-up of sticky Carbon deposits is created, slowly solidifying over time and effectively choking the system. EGR valves are also affected by carbon buildup.

5. What are the effects of carbon buildup?

Over time this build-up restricts air flow to the point where efficiency of the engine becomes impacted and fuel economy suffers. In very serious cases it could even end up with damaged seals and the engine needing to be replaced.

One of the most common issues drivers face is battery failure during the colder months. Why is this? The cold weather significantly impacts the chemical processes inside a battery, reducing its ability to hold a charge. As temperatures drop, the battery’s capacity decreases, while the engine requires more power to start due to thicker engine oil. This creates the perfect storm for battery failures, making it essential to choose a battery that's up to the challenge of cold weather.

Keeping your vehicle running safely and smoothly starts with regular log book servicing. At Peers Motors Pinnaroo, your trusted Repco Authorised Service centre in Pinnaroo, we carry out servicing that protects your warranty, preserves your vehicle’s reliability, and helps prevent costly repairs down the track.

Log book servicing is a scheduled service program set by your vehicle’s manufacturer. It outlines specific checks, adjustments, and parts replacements required at certain intervals—usually based on kilometres travelled or time passed. Even if you don’t have the physical log book with you, there’s no need to worry.

Peers Motors Pinnaroo follows the manufacturer’s guidelines using industry-leading Repco information systems and qualified technicians. This means your service is completed to the same standards as the dealership, and your warranty remains intact.

A log book service ensures your vehicle’s core systems—engine, brakes, suspension, steering, tyres, electrical components, and safety features—are checked and maintained at the right time. It keeps your car performing as intended and reduces the risk of unexpected breakdowns.

Even if you haven’t reached your next scheduled interval, pay attention to:

Any of these can indicate that components are wearing out or lubricants and filters need attention.

Skipping services doesn’t just impact one part—it can lead to a chain reaction:

Old engine oil can cause excessive engine wear

Blocked filters can reduce performance and fuel economy

Worn brake components can affect ABS performance

Neglected cooling systems can cause overheating, especially in hot Australian summers

Tyre wear can worsen suspension and steering issues

Regular servicing protects your whole vehicle, not just the individual parts being replaced.

Driving conditions in Australia vary dramatically between seasons, and vehicles experience different stresses during summer and winter.

Seasonal Servicing: Summer vs Winter Safety Checks

Australian summers—especially in places like Pinnaroo—bring extreme heat, long road trips, and more stop-start city traffic. A summer safety check focuses on:

Battery health (heat reduces battery lifespan)

In cooler months, your car faces cold starts, moisture, and reduced traction. A winter safety check prioritises:

Summer checks aim to prevent overheating and ensure reliable long-distance travel, while winter checks focus on visibility, traction, and cold-weather starting problems.

Modern cars can have more than 30 onboard computers, and many service items include software checks and updates—not just mechanical work. This is why specialist diagnostic equipment, like that used at Peers Motors Pinnaroo, is essential.

Whether you’re navigating urban traffic, coastal humidity, regional heat or country roads, Pinnaroo driving can be demanding. Dust, temperature swings, and stop-start conditions all increase wear on critical components. Our technicians understand local conditions and adjust your servicing needs accordingly.

A vehicle's cooling system is a critical component that ensures the engine operates efficiently and reliably. Without an effective cooling system, engines can overheat, leading to potential damage and costly repairs. Here, we explore the workings of radiators and cooling systems, the benefits of coolant flushing, and what to watch out for to prevent system failures.

A vehicle's cooling system is designed to remove excess heat from the engine, ensuring optimal performance and longevity. The primary components of the system include the radiator, water pump, thermostat, and coolant. The water pump circulates coolant through the engine, where it absorbs heat. The heated coolant then travels to the radiator, where it is cooled by air before circulating back to the engine. The thermostat regulates the coolant flow based on the engine's temperature, maintaining an optimal operating environment.

Over time, contaminants such as rust, scale, and other deposits can accumulate within the cooling system. These contaminants can clog the system, reducing its efficiency and potentially causing overheating. Regular maintenance and inspection are vital to ensure that the system remains free from obstructions that can impair its function.

Coolant flushing is a preventive maintenance procedure that involves removing old coolant and contaminants from the system and replacing it with fresh coolant. This process helps maintain the efficiency of the cooling system, preventing corrosion and reducing the risk of overheating. Regular coolant flushes can also extend the life of the engine by ensuring that it operates at the correct temperature.

Several signs may indicate a problem with the cooling system. These include:

Overheating: The most obvious symptom, often indicated by the temperature gauge reading higher than normal.

Coolant Leaks: Visible leaks or a low coolant level can suggest a problem.

Unusual Noises: Sounds such as grinding or hissing can be indicative of issues within the system.

Steam or Smoke: Emissions from under the bonnet are a serious sign of overheating.

When a cooling system fails, the engine can quickly overheat, leading to significant damage. Potential issues include:

Potential Damage from Cooling System Failure

Warped Cylinder Heads: Excessive heat can cause the cylinder heads to warp, leading to a loss of compression and engine performance.

Blown Head Gasket: An overheated engine can cause the head gasket to fail, resulting in leaks and a drop in engine efficiency.

Engine Block Damage: Prolonged overheating can crack or warp the engine block, requiring costly repairs or replacement.

For residents in Pinnaroo, maintaining your vehicle's cooling system is crucial for its longevity and reliability. Peers Motors Pinnaroo offers comprehensive cooling system services, including inspections, coolant flushing, and repairs. With their expertise, you can trust that your vehicle will be in capable hands, ensuring you stay on the road safely and efficiently. Visit Peers Motors Pinnaroo today for all your automotive needs.

Radiators and Cooling Systems: Essential Knowledge for Your Vehicle

If your vehicle is suffering from poor fuel economy, a lack of power when accelerating, an overall lack of power or the engine seems to be abnormally hot all the time it could be time for a carbon clean.

Diesel engine intake and carbon cleaning is an essential but often overlooked part of maintaining a modern diesel engine.

Most people do not realise how much carbon builds up in their engines. It accumulates on pistons, rings, valves and injectors. Build up in EGR valves and intake manifolds causes engines to run rough, have reduced power and use more fuel.

Since 1999 most cars in built in Australia will have an EGR system of some kind. If your vehicle is fitted with an EGR system there is something you should know.

Carbon buildup in EGR Valves and the Intake Manifold could be choking your engine.

This can happen to both petrol and diesel engines but turbo and diesel engines tend to be more susceptable to the problem, especially where a PCV system is used. Peers Motors Pinnaroo have the skills and equipment to give your engine a full carbon clean to help ensure a correct fuel mix, improve efficiency and fuel economy and generally protect the engine.

Your vehicle's differential bushings might be the culprit if they’re old, worn, or cracked. These essential components help control movement in the joints, absorb bumps on the road, and reduce vibrations and noise whether you’re driving forward or reversing. At Peers Motors Pinnaroo, your trusted local mechanic in Pinnaroo, we’re well-equipped to handle this and many other automotive issues.  

The Ford Territory and Falcon are undoubtedly two of the most popular vehicles seen on Australian roads. However, both models are known to experience significant wear in certain rear suspension components, particularly the rear differential bushing. This is most common in vehicles that have covered high mileage, possess high horsepower, or are regularly used for towing.

If you’ve noticed a clunking noise or felt a jolt when accelerating or shifting between drive and reverse, it may indicate that your differential bushing is no longer functioning as it should. The rear differential bushing is designed to ensure a smooth and quiet transfer of power from the engine to the rear wheels, making it a vital part of your vehicle’s performance.  

Ignoring this issue can lead to additional wear and tear on other drivetrain and suspension components, potentially resulting in more costly repairs. Acting promptly when symptoms arise is both practical and cost-effective.

At Peers Motors Pinnaroo, your local Repco Authorised Service centre in Pinnaroo, our skilled team has extensive experience diagnosing and resolving this problem. We can replace your worn rubber differential bushing with a durable Nolathane alternative, which is specifically engineered to address these concerns and restore your vehicle to peak performance.

If clunking has become a regular part of your Territory or Falcon experience, don’t wait—get in touch with the team at Peers Motors Pinnaroo today.

At Peers Motors Pinnaroo in Pinnaroo, we understand how crucial the transmission is to your vehicle’s performance.  

Your transmission enables your car to shift smoothly between gears, and transmission fluid plays a vital role in making this possible. Not only does it ensure seamless gear changes, but it also protects the internal components of your transmission. While transmission fluid doesn’t naturally decrease with use, it’s still important to check its level regularly. 

Over time, transmission fluid can become contaminated with metal particles and debris, which can reduce the lifespan of your transmission. Replacing a transmission is a costly repair, so maintaining clean, adequate transmission fluid is a smart way to protect your vehicle and avoid unnecessary expenses in the long term. 

Additionally, it’s worth noting that transmissions can suffer from overheating if fluid levels are too low, as the fluid also helps regulate temperature within the system.

At Peers Motors Pinnaroo, we offer a comprehensive 65 Point Vehicle Condition Report with every full car service upon request. This includes inspecting your transmission fluid, and we’ll let you know if it needs replacing or if your vehicle could benefit from a transmission service.

Ensure smooth gear changes with Peers Motors Pinnaroo. We check and maintain transmission fluid as part of our services to keep your vehicle performing at its best. Book a service today!
