Toyota Hilux Most Common Problems

Since 1968, Toyota has been producing the Toyota Hilux series of pickup trucks, originally as a compact pickup truck until 2004 when it became a mid-size pickup truck. The Toyota Hilux is renowned for its durability and reliability and has been a popular choice globally for many years. However, even with its reputation as a giant in the industry, it is not immune to certain issues. In this article, we will be highlighting some of the most common problems associated with the Toyota Hilux.

Turbo Problems

One common issue with the Toyota Hilux is turbo-related. Symptoms of turbo issues include lack of power, black smoke from the exhaust and unusual noises. This problem is often caused by a split pipe connected to the intercooler, which results in a loss of boost pressure. A replacement pipe can resolve the issue. Proper engine oil and lubricants are also necessary to prevent damage to the turbo caused by poor-quality oil and contaminants.

Another issue with the Toyota Hilux is the potential for foreign objects to enter the turbo through the compressor and turbine inlets, causing damage to the compressor’s wheels and turbine’s blades. Regular air filter servicing and replacement can help prevent this problem.

Turbochargers can wear out earlier than expected, with a lifespan of up to 150,000 miles depending on driving habits and the quality of the turbo. Replacement of the pipe may be necessary in some cases, while proper lubrication or air filter replacement may suffice in others. It is recommended to consult an auto technician for the best course of action based on the specific issue.

Starting and Misfiring Problems

The fuel injectors on Toyota Hilux models with common rail diesel engines are known to cause starting problems and misfiring. Symptoms of this issue include fuel odour, fuel leaks, engine vibration and the check engine light turning on.

Replacing the old fuel injectors with new ones is necessary to fix this problem.

This issue is most prevalent in Toyota Hilux variants equipped with common rail diesel engines.

Causes and Solutions
Here are some potential causes and solutions to starting problems:

Faulty Fuel Injection System
The fuel injection system is essential to the smooth operation of a diesel engine. It supplies fuel to the injectors and adjusts fuel quantity and timing. Fuel injectors promote optimal fuel efficiency and cleaner emissions. However, fuel injectors may become clogged or worn out over time, leading to engine misfiring or difficulty starting. To address this issue, clean the fuel injector or replace it with a new one.

Defective Glow Plugs
Glow plugs warm up the engine cylinder to facilitate efficient fuel combustion. They help warm the engine cylinders on cold mornings when starting is difficult. If the glow plugs are faulty or defective, they may hinder engine performance and cause misfiring and difficulty starting.

What to Do
If you experience starting or misfiring problems, contact a trusted auto expert to diagnose and address the issue.

Loss of Power
Blocked Exhaust Gas Recirculation (EGR) valves are the most common cause of power loss. Carbon buildup inside the valve significantly reduces airflow, causing irregular idling. Cleaning the EGR valve will solve this problem.

Crank Seal Oil Leak

Oil leaks from the crank seal have been a common issue faced by the Toyota Hilux. The leak is typically observed as oil droplets or puddles under the car. To address this, a replacement of the crank seal is required.

This problem is highly noticeable and owners should seek prompt attention to prevent further complications.

Possible Causes and Solutions

Here are some of the reasons for crank seal oil leaks and their solutions:

Extreme Weather Conditions
The rubber material used to make the crank seal can be negatively impacted by harsh weather conditions. Prolonged exposure can cause the seal to shrink and eventually fail, leading to oil leakage.

High Mileage
If your Hilux has covered more than 100,000 miles, it is common for the crank seal to start leaking oil. The best course of action is to replace the seal to avoid further problems.

Poor Installation
Faulty installation is another reason for a leaky crank seal. It is essential to have a professional handle the replacement to ensure that it is correctly installed.

What to Do
If you suspect an oil leak from your Hilux’s crank seal, it is recommended that you consult a professional. Attempting a repair without proper expertise may be risky and worsen the problem. Professionals can accurately diagnose the issue and provide a lasting solution.

5th Gear Synchronisation

Many Toyota Hilux owners have encountered challenges shifting into the fifth gear, which suggests a problem with the manual transmission system. It is advisable to address this issue as soon as possible to prevent further damage.

Below are some potential causes and solutions for the 5th gear synchro problem:

Faulty Synchronizer Ring
The synchronizer ring is an essential part of the transmission system as it facilitates gear engagement. Difficulty shifting into any gear may indicate a problem with the synchronizer ring.

Defective Gear
Manual transmissions typically have five gears and each gear has a dual tooth that receives engagement from the synchro and hub sleeves. Damaged or worn-out teeth in the gear can make it challenging to engage.

Malfunctioning Hub Gear
The hub gear links two different gears together. For example, there is a hub gear between the 4th and 5th gears. A damaged or worn-out hub gear could cause transmission problems.

We recommend seeking the assistance of a professional technician to resolve this issue, as it can be a challenging job to fix.

While the Toyota Hilux pickup truck is known for its durability and reliability, it is not immune to common issues that may arise. Turbo problems, starting and misfiring issues, loss of power, crank seal oil leaks and 5th gear synchronisation problems are some of the most common problems faced by Toyota Hilux owners.

Proper maintenance, regular servicing, and prompt attention to issues can help prevent further complications. It is recommended to consult a professional technician for diagnosis and repair of any problem with the Toyota Hilux. Despite these issues, the Toyota Hilux remains a popular choice globally and continues to hold its position as one of the most reliable pickup trucks on the market.
