Diagram ref no 6

Engineered to OE standards, this unit replicates the original shape, mounting points, port alignment, and internal volume. Its material resists heat, oil vapor, and pressure cycling to provide reliable vacuum buffering over long-term use.

Over time, the vacuum reservoir can crack, leak, or lose internal sealing, leading to:
•  Reduced braking assistance
•  Malfunction of intake or exhaust actuators
•  Check-engine lights caused by vacuum faults
•  Rough idling or loss of power under load

Replacing the vacuum reservoir restores full vacuum stability and ensures proper operation of all connected systems. This is especially important when diagnosing brake booster failures, emissions issues, or vacuum leak codes.
