Ford F150 produce a burning smell during driving, and it is necessary to counter them because it can also increase the risk of firing in various components.
The burning smell comes from Ford F-150 because of overheating in alternators, installation of new parts, failed catalytic converters, engine overheating, burnt-out blower motor, worn-out braking system, and faulty AC compressors. Moreover, it is due to loosening serpentine belts, excessive tire rubbing, blown-out fuse, short circuits, and oil and coolant leakage.
It is better to avoid driving your Ford F150 trucks because burning smells represent malfunctioning in its different parts, and these can also get damaged when you do not stop them.

Overheating of alternators
You can see the burning smell from your Ford F150 trucks because of overheating alternators. The overheating issue comes when batteries are damaged and their wiring connections are loose.
Moreover, the faulty alternator diode and malfunctioning voltage regular make them bad and produce more heat. The temperature of these components gets high when you do not clean them and their terminals.
These damaged bearings and poor lubrication cause the problem. The issue also comes when the vent system is blocked and does not allow the hot air to move outside.
Check the alternator and replace its faulty components. Keep them clean and regularly service them to prevent overheating. Ensure that batteries are not dead and their connections are correctly fastened.
Installations of new parts
You can often feel the burning odor from your vehicle when you drive a few miles after installing new components.
The issue mostly comes when you add the components of engines, braking systems, and exhausts. People add them when one of their parts becomes bad and stop functioning.
The new components are coated with a protective layer, which can produce a terrible smell when the Ford F150 temperature rises.
The temperature increases when you drive them and turn on the ignition. You cannot see any visible smoke from them because of only the heating of the outer core.
It is better to contact the dealers if the smell lasts longer during driving. The issue also comes from their poor attachment; you can see smoke with a stinky and terrible smell.
Failed catalytic converter
Catalytic converters are primarily present in old models of automobiles to make the environment safe and increase the efficiency of Ford F150 trucks.
These are helpful in the conversion of toxic gasses from the exhaust system to less toxic ones. The failure of the catalytic converters does not remove these gasses.
The pungent smell of sulfur dioxide from the exhaust system moves inside and makes you uncomfortable. The failure of catalytic converters comes from the damaged connected parts, including spark plugs and exhaust valves. Moreover, thieves also stole them because of their costly manufacturing materials.
These can also malfunction because of bad sensors, hitting road surfaces, and dirt and dust accumulation. Therefore, regular cleaning and servicing are necessary to avoid issues with the parts of the catalytic converter.
Remove the dust and debris from them to avoid overheating and melting.
Engine overheating
The overheating in the engine produces a burning smell in your Ford F150 pickup. In addition, the temperature of the engine compartment increases because of faulty thermostats that do not maintain their temperature.
The problem comes when coolant is not moving through the pipes properly because of their low level. The coolant leakage from the radiator hose and cap also increases the temperature.
The overheating causes the burning and melting of plastic screws and head gaskets. The rubber-like smell comes from the melting of these components.
Check the coolant level and radiator fan to maintain the internal temperature. In addition, replace the head gaskets with aluminum type so they cannot melt from overheating.
Worn-out braking system
The worn-out and damaged braking system increases heat and friction between their components. The burning smell from the pickup trucks comes from the faulty braking system.
The overuse and frequent use of brake pedals during driving increase the risk of overheating and friction. Moreover, the problem comes from the leakage of the brake fluids.
The brake caliper also gets stuck and keeps the brake pedals in contact with the rotors. In addition, the worn-out and old parts of the braking system release more heat.
Check the braking components and brake fluid levels and their leakage. Replace the worn-out parts with new ones to avoid stinky smells.
Faulty AC compressors and blower motors
The faulty ac compressor can produce a burning smell from your trucks because it increases the overheating.
Overheating in compressors comes when refrigerants do not move through the clogged coils. In addition, the temperature of these components rises due to the poor lubrication of their parts.
The incorrect maintenance and poor ventilation cause the heat to remain in these systems, increasing the temperature, and people say that AC smells bad. The burnt-out motors of the air conditioning system also cause this bad smell from the vehicles.
The blower motors become faulty because of electric failure, damaged bearings, poor airflow, dust, debris, and clogged air filters.
Routinely maintain or service the compressor parts and lubricate them to reduce friction. Clean the air filters with a hairdryer and vacuum cleaner to remove dust for smooth airflow.
Loose serpentine belts
The serpentine belt runs along your Ford F150 and is made of rubber material. The primary function of a rubber serpentine belt is to transfer power to the respective components of the engine.
The overheating in the engine affects the functioning of serpentine belts. These do not sufficiently transfer the power and become loose.
These can also come out from the pulley and cannot function. This is because the friction increases, and rubber parts start to melt when these come off from the tensioner pulley.
You can feel the rubber-like burning smell from these components because of oil and fluid leakage. You can add belt conditioners or lubricants to prevent it from slipping from the pulleys.
Excessive tire rubbing
The excessive tire rubbing with road surfaces increases friction between the wheels and the ground. The excessive rubbing of wheels on roads also increases the chances of overheating.
The rubber tires produce a burning smell when exposed to excessive heat from the road. The issue comes when you apply brakes frequently during driving.
Moreover, the heavy hauling puts pressure on tires and increases friction between them and ground surfaces. You can also face the problem when tires are underinflated and are not aligned properly.
Inflate the tires properly and keep the air compressors with you while off-roading. Avoid heavy hauling and frequent brake application because it produces more heat.
Blown-out fuse and short circuits
Various fuses are present in pickup trucks because of the electrical components. Each electrical system has a separate fuse to control the power supply.
The fuse prevents its respective component from getting damaged by preventing a power supply surge. It blows out, so power cannot reach these parts.
Fuses are less costly to replace instead of damaged components. However, the blown-out fuse causes a burning smell in vehicles; you can identify them from their brown color.
Moreover, the wires are also running to provide electric current. The damaged and loose connections produce short circuits and a burning smell.
Use the correct amperage fuse and avoid touching them frequently during installation to reduce the chances of their blowout.
Track the wires to find the short-circuited wire and replace them.
Oil and coolant leakage
The oil and coolant leakage from the engine compartments comes into the exhaust system. The burning smell from Ford F150 trucks comes when the exhaust fumes of oil and coolant leak.
Oil leakage occurs when crankshaft and camshaft ventilation or seals are bad. The oil comes from the exhaust pipes due to damaged head gaskets.
The damaged oil filler cap and worn-out gaskets cause the problem. In addition, coolant also comes from the heater cores and exhaust systems and produces a bad smell.
This is because the air is trapped from the outer source. However, the damaged radiator hose and cap can also cause coolant leakage.
Check the oil level in the engine by using the dipstick method. Replace the gaskets, seals, radiator cap, and hose if these are worn out.
