When a car owner hears a hissing sound coming from under the hood, it’s usually time to start checking the vacuum lines. Vacuum lines are an essential part of a car’s emissions control system, and they deliver air or fuel to various parts of the engine. These lines are crucial to the proper functioning of a car’s engine as they regulate the flow of air and fuel, and more. However, vacuum lines are also prone to damage, causing a myriad of problems for car owners. This article will highlight some of the reasons why vacuum lines break.
Exposure to heat
Vacuum lines are made from rubber material that can withstand high temperatures to a certain degree, but consistent exposure to extreme heat can damage them over time. If you live in hot areas or drive for extended periods, vacuum lines could wear out faster than usual, causing them to break.
Aged Lines
Like all components, parts that are subjected to constant use will eventually wear out or deteriorate. Vacuum lines are no exception. With time and use, vacuum lines begin to lose their elasticity, making them rigid, brittle, and prone to cracking, splitting, or breaking. Experts recommend changing your vacuum lines every 4 – 6 years, depending on the car’s usage.
Incorrect Installation
A car’s vacuum lines may require replacement now and then, but improper installation can lead to vacuum leaks and breakages. During installation, if vacuum lines are stretched too much or not aligned correctly, the lines become weak, reducing their lifespan. To avoid such issues, it is recommended to have a professional car mechanic install the replacement vacuum lines properly.
Abrasion
Another reason why vacuum lines break is abrasion. The vacuum lines frequently run across several sharp and rough-edged components of the engine that rub against the hoses over time, causing them to deteriorate. To avoid vacuum line abrasion, manufacturers suggest routing vacuum lines away from sharp edges and using sleeves or caps to protect them for longer-lasting performance.
Age-related wear-and-tear
The wear-and-tear of aged vacuum lines is pretty common. The more a car ages, the greater the chances of vacuum line breakdown. As parts continue to reach the end of adjustment, weakened or old hoses can result in engine failure or a reduction in performance. Regular engine inspections and maintenance will identify hoses that require replacement, and it is recommended to replace hoses when cracks, weaknesses, or damages are present.
In conclusion, regular vacuum line inspection and maintenance can help avoid breakdowns and save you significant costs down the line. If a vacuum line breaks, call a professional mechanic to replace it. Never try to fix the line yourself, as engine errors could lead to bigger, more costly problems.

Frequently Asked Questions about Why Vacuum Lines Break
What are vacuum lines?
Vacuum lines are rubber hoses that connect various components of a vehicle’s intake and emissions systems to a vacuum source. They are responsible for controlling many different functions within a car, including emissions control, power brakes, and air conditioning.
What causes vacuum lines to break?
There are several reasons why vacuum lines might break. Over time, they can become dry and brittle as a result of exposure to heat, chemicals, and other environmental factors. They can also become damaged if they come into contact with another part of the engine or if they are pinched or twisted during installation or maintenance.
What are the symptoms of a broken vacuum line?
When a vacuum line breaks, it can cause a number of different problems with your car. These can include rough idling or stalling, a loss of power or acceleration, reduced fuel efficiency, and even engine damage. If you notice any of these symptoms, it’s important to have your car checked by a mechanic as soon as possible.
Can I replace vacuum lines myself?
If you’re experienced with automotive repair and have the right tools, you may be able to replace vacuum lines yourself. However, it’s important to use the correct type of hose and to install it properly to ensure that it functions correctly. If you’re not confident in your ability to do this, it’s best to leave the job to a qualified mechanic.
