    Home News My Toyota Hilux 3. My Toyota Hilux 3. There seems to be mainly two problem areas experienced with the Toyota Hilux 3. Injector failure Do you experience noise and excessive white smoke during a cold start?

    These are the symptoms of a faulty injector. Yes, the D4D system commonly present itself with injector problems, but this not Hilux-specific; all common rail diesel engines tend to suffer the same fault, but why? The reason is that diesel fuel has to comply with emission laws; fuel companies therefore add additives to reduce emissions and these additives create sticky deposits in the fuel system.

    Whenever these deposits even in miniature quantities find their way into the injector, you are in for some trouble. Your vehicle will start to experience rattling to various degrees , and the only thing to do is to replace the injectors.

    If you fail to do this, it can cause immense internal engine damage, leading to motor failure. There are a few preventative steps which may be taken: Rail injectors should not be introduced to Bio Diesel.

    Dirty diesel is the biggest killer of injection systems. That is why you should always fill up at reputable and well-maintained fuelling stations. The best thing to do is to bring your vehicle to your nearest Steves Auto Clinic and have the injectors tested.

    The cost of having these done will far outweigh the costs of replacing broken injectors. Owners sometimes fit an extra inline diesel filter and a water trap — connected in series to the already present filter — to protect the sensitive injectors. Steves Auto Clinic, at the request of vehicle owners, can assist in this regard. One could easily mistake this noise for an injector failure, but below the rpm mark it tends to do that, especially in the morning when the engine is cold.

    After about km, the noise may go away as the engine heats up. The reason is that the lifters are still dry and only get lubricated after a few kilometers. The rattling sound is therefore normal, in this sense, but to play safe, have Steves Auto Clinic give your vehicle a thorough inspection to make sure that any noises may not be the start of something more serious.

    Low grade oil being used This is a common problem, and this tendency should be avoided. Many a Hilux 3. Using low grade oil will result in an excess of heat building up due to poor friction. This in turn results in carbonisation and supply blockages as seen in the oil pick up below.

    If this ever happens, be sure to embrace yourself for an engine change because sludging to this extent can never fully and properly be cleared from the oil galleries. This ought to be done every 60 km, to be on the safe side. Turbo fails to kick in If it feels as if your Hilux 3. Also have the EGR exhaust gas recirculation system checked because this may be dirty.

    Water Pump Finally, you may also think of having your Hilux 3.

    What is a Toyota D-4D engine? This type of diesel engine injects fuel into the engine as a fine mist, under high pressure. It offers better fuel efficiency and lower emissions than a petrol engine.

    D-4D engines are famous for reaching very high mileage with no issues. What are common Toyota D-4D diesel injector problems? After a certain mileage, Toyota D-4D diesel injectors — or common rail injectors — will eventually fail and have to be reconditioned or replaced. The average life span of Toyota diesel injectors is 8 to 10 years, or between and kilometres.

    Toyota injectors can also fail prematurely, even at low mileages, due to blockage, sticking or fuel contamination. If an injector fails, it will interfere with fuel supply. This can lead to catastrophic engine failure and very high engine rebuild costs. In newer common rail diesel engines, like the Toyota D-4D, engine modifications designed to reduce sulphur emissions have resulted in diesel injectors with extremely fine tolerances.

    Toyota Hilux, Prado and Fortuner injectors depend on near-perfect filtration and lubrication. Internal seal failures are also a common Toyota D-4D injector problem. Diesel, we offer expert Toyota Fortuner and Toyota Hilux diesel injector reconditioning. We can also replace Toyota injectors, expertly and at a reasonable price. What causes rattling or misfiring of a Toyota Hilux, Prado or Fortuner fuel injector? Sometimes this is simply because you started a diesel engine at a low temperature.

    More serious causes include internal diesel injector leakage, damage to the seals of the combustion chamber or coolant leakage. To determine the cause, have your vehicle professionally evaluated. Wish I had taken it in ages ago as it had always smoked and agents just tried to talk the problem away. It is now much improved. My fuel economy is better, increased from average actual measured range of I also no longer cover vehicles behind me in a plume of black smoke.

    My D4D had a serious black smoke issue since I bought it. Excellent service. Always kept me up to date so I knew exactly what the status was and what will happen next. You guys come highly recommended! Diesel for the great service I received in reconditioning the injectors on my Fortuner.

    They provided excellent service and communicated clearly every time they made contact to keep me up to date with progress. Thanks guys.

    Saved pulling engine out and honing. Also mates golf buggy was blowing heaps of smoke because lack of maintenance, double dosed the fuel by the end of the game smoke gone. Saved an engine rebuildBrilliant product and I highly recommend using all of Cost Effective Maintenance products. Definitely worth the money! I have been using FTC Decarboniser and ran an oil flush through it at 1.

    Still does not use a drop of oil between 20,km service intervals. Had my mechanic pull the sump off to do a bearing roll at Christmas and we found insides spotless, even still has cross hatching in the bores!

    Sump and head haven't been off before.

    I absolutely No wonder the mining industry uses CEM products as part of their maintenence schedule. Yes, I'm a devote regular customer.

    Have been using CEM products for nearly 20 years. Never looked But the tractor was a definite improvement, the engine ran sweeter and a lot less gunk from the exhaust, really noticeable. Thoroughly recommend, the only suggestion is to maybe reconsider the product names But names are not everything, absolutely worth the money. Many thanksread more gary clothier 14 Oct 20 Using both the Petrol and Diesel additives and car idles and runs better as well as improved Using FTC Decarbonizer and are totally converted.

    I have been using the FTC Decarbonizer for the last My mechanic has warned me the engine on my Winnebago Motorhome Chevy 6. There is now no evidence of smoke from the exhaust under load, the performance has improved, the engine just runs smoother, but incredibly it starts first time after being a difficult starter for several years. I am looking forward to its next service to see what the mechanic has to say.

    Great product. I have been using their engine and Service is terrific, and advice is accurate and helpful. These products are simply the best there are. It has made a HUGE difference in all of them. My little After using the AW10, it is quiet and the temp takes a while to get to it's working temp. The car runs really well now. All the other cars are running well too.

    Works so much better than anything else I have tried. I first saw the XTroll rust treatment way back in the late 80's.
