The Toyota Hilux is a series of pickup trucks manufactured by Toyota since 1968. Toyota designed the Hilux as a compact pickup truck between 1968 and 2004, and starting in 2004, it became a mid-size pickup truck. This time we bring you the common faults of the Toyota Hulix, so stay with us and keep reading.
Hilux has gained a lot of popularity and has become one of the best-selling and most sought-after pickup trucks around the world. However, like any vehicle with the passing of time, it presents its problems.
Toyota Hilux Common Faults
Known for its durability and reliability, the Toyota Hilux has enjoyed great popularity around the world for decades. However, even the giants have their weaknesses; therefore, in this article, we will talk about some of the most common Toyota Hilux problems.
1. Turbo problems
There have been several complaints about the Toyota Hilux turbo. Complaints border on the palpable lack of power and the unpleasant dark smoke coming from the exhaust.
Some owners have also claimed to hear a strange noise coming from the turbo, which is also ominous. Turbo problems eventually lead to a complete loss of boost pressure and therefore require immediate attention.
Possible causes and solutions
Here are some of the causes of Hilux problems and their solutions:
1- Lack of adequate lubrication
Every car needs motor oil and lubricants, especially for moving parts, as it helps prevent corrosion and keep them in good condition.
The turbo also needs a regular flow of clean oil to keep it running smoothly. When the turbo is starved of oil or poor quality oil is supplied to it, contaminants will almost certainly show up and cause serious damage.
2- Defective seals
There are gaskets between the supercharger and the engine, and if they wear out, oil will leak into the exhaust. Consequently, this will put an unusual load on the turbo when increasing the air pressure.
Finally, it will reduce the boost delivered by the turbocharger.
3- Foreign objects
The compressor and the turbine are two of the fundamental components of the turbo. Unfortunately, both components have inputs that can input objects like dirt, small stones, leaves, and the like.
If this happens, the efficiency of the turbo will be reduced, as objects often damage the compressor wheels and turbine blades.
The best preventative measure against this is to have the air filter checked and changed regularly.
4- Worn Turbo
Turbochargers are often expected to last up to 150,000 miles (241,000 kilometers). However, they can wear out sooner, depending on your driving habits and the quality of the turbo. In this case, what you have to do is replace the tube.
Not all turbo problems require pipe replacement; some just need proper lubricants or air filter replacement. This is why we advise you to consult an auto technician to find out the best way to act.
2. The truck has a hard time starting
One of the most common Toyota Hilux problems is misfiring and starting problems. The often suspected reason for this is a problem with the fuel injectors.
The problem is more common in variants of the Toyota Hilux that are powered by common rail diesel engines. Other possible symptoms are a strong smell of fuel, fuel leak, engine chattering, check engine light coming on, among others.
Possible causes and solutions
Here are the possible causes and solutions to boot problems:
1- Defective fuel injection system
The fuel injection system is crucial to the proper functioning of a diesel engine. It helps supply fuel to the injectors and also makes adjustments to fuel quantity and timing.
Fuel injectors facilitate optimal fuel efficiency and keep emissions cleaner.
Most fuel injectors last around 100,000 miles (161,000 kilometers). However, they are vulnerable to clogging and can wear out. Clogged or worn fuel injectors can cause engine misfiring or hard starting.
The solution to this is to clean the fuel injector or replace it with a new one.
2- Defective spark plugs
Spark plugs heat the engine cylinder to facilitate effective combustion of fuel. On cold mornings when starting is difficult, they help warm the engine cylinders.
Therefore, if the glow plugs go bad or are faulty , they can hamper engine performance and lead to misfiring and hard starting.
As we have seen above, hard starting or misfiring problems are probably problems with the fuel injectors or glow plugs. However, we advise you to inform your dealer or a trusted automotive expert to locate the problem and find a lasting solution.
3. Oil leak from crankshaft seal
The Toyota Hilux has faced countless criticisms related to oil leaking from the vehicle’s crankshaft seal. Fortunately, oil leaks are easily noticeable because they often puddle under the truck.
This problem usually means a crankshaft seal failure, which needs to be addressed as soon as possible before it gets worse.
Possible causes and solutions
Here are some of the reasons why the crankshaft seal has been leaking oil:
1- Adverse weather conditions
The crankshaft seal is made of rubber, and its elasticity makes it vulnerable to excessive temperatures. Eventually, the crankshaft seal shrinks and gives way completely, causing an oil leak.
2- High mileage
If you have completed more than 100,000 miles (161,000 kilometers) with your truck, it is normal for the crankshaft seal to break. The best course of action is to have the crankshaft seal replaced.
3- Faulty installation
Many owners complain that the crankshaft seal leaks soon after getting a replacement. If this happens, do not rush to replace the component again. It is likely an installation issue. Crankshaft seal installation is not as easy as it sounds and is best done by professionals.
If you suspect that your Hilux has a faulty crankshaft seal, we advise you to have it checked by a professional. Taking matters into your own hands can be very risky, as crankshaft seals are delicate components and best handled by experts.
4. Difficulty getting into 5th gear
A good number of Toyota Hilux owners have also complained of unusual difficulty getting into fifth gear. This portends a problem with the manual transmission and should be attended to immediately.
Possible causes and solutions
Here are the possible causes and solutions for this problem:
1- Defective synchronizer ring
The synchronizer ring is crucial to the transmission system as it helps it to engage gear. It is the reason why you can turn their gears and expect them to respond accordingly.
If you are having difficulty getting into any of the gears, the problem is most likely with the synchronizer ring.
2- Defective gear
Most manual transmissions have gears 1 through 5. Each gear has something like a double tooth, which receives the synchronizer engagement with the hub sleeves. However, if these teeth become damaged or worn, it becomes difficult to use the gear.
3- Bad hub gear
The hub gear is responsible for the engagement between two different gears. For example, there is a hub gear between 4th gear and 5th gear. If the hub gear is damaged or worn, it could cause transmission problems.
If you have problems with the 5th gear of your Toyota Hilux or with any of the gears, it is best that you go to a trusted technician, in this way you can find the particular problem and give it a suitable solution.
