Burning Smell in Truck: Major Causes
Below are the most common causes of burning smell coming from your truck:
Overheated brakes
One of the most common causes of a burning smell in trucks is overheated brakes. Drivers may encounter this smell, especially when driving through steep terrain or during stop-and-go traffic. This smell is often sharp and reminiscent of burning rubber. Brakes become extremely hot when they are used excessively, causing brake pads to emit this distinctive odor.
To avoid the burning smell coming from your truck due to overheated brakes, truck drivers should allow brakes to cool down before resuming driving. Plus, avoid excessive braking on long descents by using lower gears or engine braking whenever possible.
Clutch problems
A slipping clutch in trucks with manual transmissions can generate a burning smell similar to scorching paper. One may notice it when shifting gears or climbing steep hills in Australia. What causes it, you ask? This can happen when your truck’s clutch wears down, resulting in excessive heat buildup due to friction between the clutch plate and flywheel.
If this smell is coming frequently from your truck, it usually indicates your clutch may need replacement. Have a mechanic check the clutch promptly if this issue persists.
Electrical issues
Short circuits and overheated wires are another common source of burning smells in trucks. Often resembling melting plastic, these electrical issues in your truck are particularly dangerous. Not only do they threaten your truck’s systems but also increase the risk of fire. Endangering both the driver and others on the road.
Always consult with a professional mechanic at the first sign of an electrical issue. Regular electrical inspections can help you catch and resolve these problems beforehand. Thus, reducing the risk of potential fire hazards and costly repairs.

Oil leaks
Oil dripping onto hot engine parts like exhaust manifolds is another common cause of a burning smell in trucks. This creates a distinct pungent odor that has had to be ignored.
Always check your engine for leaks and address any issues promptly to prevent this. Cleaning up spilled oil can also help reduce lingering smells and prevent further burning.
Coolant leaks
When coolant leaks onto hot engine parts, it can create a burning smell as it evaporates. Coolant leaks are especially concerning as low coolant levels can lead to overheating and severe engine damage.
To avoid these, regularly inspect the coolant system of your truck for any leaks. Repair any detected issues as soon as possible to maintain safe operating temperatures and optimal performance.
Transmission fluid leaks
Transmission fluid is essential for smooth transmission operations in your truck. When it leaks and hits the hot surfaces, it emits a sharp chemical-like burning smell that is super hard to miss.
