OEM Vacuum Reservoir for the 2002 - 2006 Nissan Altima equipped with the 2.5L QR25DE.

The Vacuum Reservoir, also known as a vacuum canister, is a component of the vehicle's vacuum system that stores vacuum pressure for use by various systems, such as the brake booster, HVAC system, and emissions control system. Over time, the vacuum reservoir may become worn, damaged or develop leaks, and may need to be replaced.

Here are some signs that the vacuum reservoir may need to be replaced:

• Poor braking performance:The vacuum reservoir plays a crucial role in the brake booster system, and a failing reservoir may result in reduced braking power or a hard brake pedal.
• HVAC system problems:If the vacuum reservoir is failing, the HVAC system may not work properly, leading to issues such as poor airflow, incorrect temperature regulation, or defrosting issues.
• Illuminated Check Engine Light:A faulty vacuum reservoir can cause emissions control system problems, which can trigger the check engine light to come on.
• Whistling or hissing noises:If the vacuum reservoir has developed a leak, it may produce a hissing or whistling sound from the engine bay.
• Vacuum system malfunction:If the vacuum reservoir is failing, other vacuum-powered systems such as the cruise control or power locks may malfunction.

Replace your insufficient Vacuum Reservoir with this genuine Nissan replacement part.
