What is a Vacuum Line in a Car and What Does it Do?
A vacuum line in a car is a hose or tube that connects various components of the engine to the intake manifold. Vacuum lines play a critical role in the functioning of the engine by carrying vacuum to different components such as the brake booster, emissions control systems, and HVAC (heating, ventilation, and air conditioning) controls. These lines are typically made of rubber and can become corroded or leak over time, leading to various engine problems.
