Fuel injectors are the beating heart of your diesel engine and the quality of fuel you run through them has a major impact on their lifespan. Whether in your truck, heavy machinery or stationary generator, knowing how to identify when fuel is impacting your engine and what can affect its quality, can save the motor you depend on.
How to tell if your fuel has gone bad
There are four main signs that can signal that your fuel could be causing problems with your injectors including low RPM, dark smoke, bad smells from the engine and cloudy fuel.
Reduced power and low RPM in your engine could be a sign poor fuel is affecting from clogs or blockages affecting the amount of fuel able to be injected.
Smoke coming from the engine is always a red flag but if it is very dark it could be a sign your injectors have been clogged by the fuel and you need to get your engine cleaned right away.
If you’re getting an off or bad smell coming from your engines while driving, its could be poor quality fuel causing a leak from the nozzles or your engine is having to work too hard.
It’s a good idea to always check your fuel before putting it in if its been stored as cloudy fuel could be a sign of loss of quality. If the clarity of the fuel has been impaired it might be a sign there is debris that could line the engine and cause blockages.
Western Australia has set off to a scorching summer, with the mercury already rising above 40 degrees as early as November in Perth.
The sweltering heat is problematic for those working out in the conditions, and the same goes for your diesel truck and a variety of machinery such as earthmoving equipment and forklifts.
With the heat directly impacting your truck’s performance, it is more important than ever to ensure you diesel cooling system is in optimum condition to maintain efficiency and reliability.
How does heat affect performance?
High temperatures put extra stress on your diesel engine cooling system because it has to work overtime to keep temperatures down.
The engine is kept cool with help from a water pump, which pushes water and coolant through galleries in and around the engine block.
As it passes through, the mixture draws out the heat caused by combustion and the friction of the moving components.
The water carries the transferred heat back to the radiator, where it is cooled by the fan and outside air (keeping in mind this is much hotter in summer) before returning to the motor.
This circuit repeats continuously during use to keep the engine within ideal working temperatures.
This is why any disruption to this system can lead to extensive leaks and damage and will require a visit from our mobile diesel mechanic in Perth.
Prevention is key, so have a chat with the Diesel West team to organise a Perth truck service to ensure your diesel cooling system is in optimal condition and avoid disruptive breakdowns and downtime.
Flush the system
As part of the service, your Diesel West mechanic will inspect your coolant system for leaks and coolant condition, and if required, flush the radiator and have it refilled with high quality engine coolant.
It is natural for scale and rust to build-up in the system over time, but this will affect the radiator’s ability to remove heat from the coolant. By flushing the system, you will effectively remove any debris which may have been affecting its performance.
Our expert team will also examine the condition of all your belts and hoses, as well as check your diesel vehicles fan and thermostat.
A simple step you can complete is to keep the outside of your radiator free from bugs, dirt and debris. These can inhibit airflow through the radiator and decrease cooling efficiency.
Engine oil has the primary responsibility of lubrication, but also plays a part in removing heat from the engine, like the water flowing through your radiator.
Heat is generated from the combustion of diesel and friction caused by the moving parts, such as the pistons and valve springs.
By reducing the amount of friction between the parts, you can manage the heat produced in the engine. This is done using quality oil and quality filters which are regularly changed.
Among its many other roles, engine oil transfers heat away from the lubricated engine components during operation.
As the oil travels around the motor, it absorbs increasing amounts of heat, before transferring to the coolant through the engine oil cooler & then to the engine sump to be cooled by the external air.
Once it has been cooled, it is recirculated through the system.

Hydraulic systems can be basic or very complex depending on system design & function.
But they all have they same basic preventative maintenance principles:
Lack of servicing can cause the system to not function as intended, hydraulic pumps to fail and oil leaks to develop.
Carrying out regular preventative maintenance on your hydraulic system such as hydraulic filter changes, oil changes, fixing hydraulic oil leaks can ensure your hydraulic system on your truck, wheel loader, skid steer or excavator will work hard for you & your business day in day out.
If you have hydraulic faults or need some servicing and repairs on your earth-moving equipment or other machinery get in touch with Diesel West
Most modern day diesel engines have a Diesel Particulate Filter or DPF as standard to meet government set emissions control. This brings in other maintenance requirements.
In normal operation the DPF is activated automatically on your vehicle whether it’s a car, 4wd or Japanese truck. As long as they are fitted from factory with a DPF system.
There is some key points to remember:
If you have a DPF warning lamp or flashing check engine light your DPF system may need some diagnostics carried out and require repairs to the Diesel Particulate Filter system.
In simple terms no, but there’s more to it.
A major reason for people choosing to get there vehicle or machinery serviced by the dealership is “it will void my warranty”. This is not true, providing the mechanic that has previously serviced the vehicle is qualified, registered & has used reputable or genuine parts.
If you’re comparing genuine vs aftermarket parts pricing it’s worth finding out what brands your mechanic is using. If your mechanic is using a reputable brands for their aftermarket parts than there will be no product quality issues as most reputable brands can’t afford to have a “bad name” in the industry they are supplying parts to.
Non-dealer servicing is usually cheaper mainly because their overheads are lower, but it’s important to note that they can’t carry out any warranty work in regards to issues covered under your warranty.
Diesel West uses high quality aftermarket parts whenever possible to pass on the lower pricing to our customers. If you need 4wd, commercial vehicle, truck or earthmoving machinery servicing or repairs contact us to discuss.
If you have heard of diesel engines clogging up their intake systems and costing a lot of money on repairs, then you’ve probably heard of fitting a catch can.
Modern diesel engines are designed to burn as much of its own fuel burn by-products as possible to help with emissions control.
During the combustion process not all the pressure created by the burning fuel is sealed in the combustion chamber, the small amount that escapes becomes what is called “blow-by”, which then goes out through the crankcase ventilation. This blow-by contains an “oil mist” which then sucked into your engine intake system. Over time, the oil accumulates to leave an oily residue from the point of entry to the intake system all the way into the engine.
There is also Exhaust-gas-re-circulation or “EGR” systems fitted to all modern diesel engines. Similar to the “oil-mist” is re-ingested into the engine via the intake system usually into your engine intake manifold. This exhaust gas contains a lot of exhaust contaminants & carbon.
How does this become a problem?
When the exhaust gas enters the intake it sticks to the fine oil residue on the inside of your intake manifold. Over time, this can build up and even block up your intake ports to the engine, as well as covering engine management sensors.
This is where you come into problems with the diesel engine starting, running smoothly or using more fuel.
One of the ways you can help limit this is by getting a diesel engine catch can fitted to your vehicle.
The catch can will help filter out the oil mist from the air intake which will then drastically lower the amount of carbon build up in your engines intake manifold. It will also reduce the oil build up that can accumulate in intake pipes, hoses, inter-cooler & can coat airflow sensors or other sensors on your intake system.
When it gets to the stage that the engine no longer runs smoothly or the cause has been determined to be the intake system build up, there’s only one option….to pull it apart, get it clean, then put it back together.
If you’re looking at installing a catch can on your vehicle, Diesel West can help.
Maintaining your trucks brake system is essential to make sure your truck stops safely, whether you carry large loads or a smaller delivery truck they all play an important role….to stop your truck.
