A vacuum hose is used on an automobile engine to precisely operate various components. When vacuum hoses fail, a number of problems may be caused that result in poor engine performance.
Vacuum hoses are thin rubber hoses that are used to deliver vacuum to numerous engine components. Vacuum hoses are designed to be flexible, yet rigid enough to not collapse when under heavy vacuum. Though similar in appearance, vacuum hoses are not interchangeable with emissions and fuel hoses. These hoses are designed to resist deterioration from contact with chemicals and may collapse from vacuum pressure.
Though often neglected until leaking or broken, vacuum hoses should be regularly inspected for damage. Hoses that show cracks, wear from abrasion or heat, or collapse easily when pinched should be replaced. Vacuum hoses may also become clogged from sediments.
When replacing vacuum hoses it is important to use an identical hose. Both inner and outer measurements are important to assure the hose can carry the required amount of pressure. Vacuum hoses should be placed to avoid tight turns that can cause the hose to kink. It is important to assure that the hose is not in contact with hot or moving parts that may damage the hose.
