Causes of Smoke Coming from Under Hood Passenger Side

Engine Overheating

One of the most common causes of smoke coming from under the hood passenger side is engine overheating. When the engine overheats, the coolant may boil and turn into steam, which can escape through the radiator cap or the coolant reservoir.

This steam can be seen as smoke coming from under the hood. Overheating can be caused by a variety of factors, including a malfunctioning thermostat, a damaged water pump, or a leak in the cooling system. It is important to address engine overheating as soon as possible to prevent further damage to the engine.

Oil Leak

Another common cause of smoke coming from under the hood passenger side is an oil leak. Oil leaks can occur due to a variety of reasons, including a damaged valve cover gasket or a cracked engine block.

When oil leaks onto hot engine components, it can burn and produce smoke. It is important to address oil leaks as soon as possible to prevent further damage to the engine and to avoid the risk of a fire.

Coolant Leak

Coolant leaks can also cause smoke coming from under the hood passenger side. Coolant leaks can occur due to a damaged radiator, a damaged hose, or a damaged water pump.

When coolant leaks onto hot engine components, it can boil and produce steam, which can be seen as smoke coming from under the hood. It is important to address coolant leaks as soon as possible to prevent further damage to the engine.

Electrical Short Circuit

An electrical short circuit can also cause smoke coming from under the hood passenger side. Short circuits can occur due to damaged wiring, a malfunctioning alternator, or a malfunctioning battery.

When a short circuit occurs, it can cause electrical components to overheat and produce smoke. It is important to address electrical short circuits as soon as possible to prevent further damage to the electrical system and to avoid the risk of a fire.
