Removal (First Design)
- If replacing the vacuum check valve and/or the upper vacuum hose, disconnect the vacuum check valve from the brake booster.
- If the vacuum check valve needs to be separated from the upper vacuum hose, release and reposition the clamp on the vacuum hose, and remove the valve from the hose.
- If replacing the vacuum check valve, remove the grommet from the brake booster and discard the grommet.
- Release and reposition the clamp on the upper vacuum hose, and remove the vacuum hose from the lower vacuum hose and pipe assembly.
- If replacing the lower vacuum hose and pipe assembly, release the vacuum hose connector retainer, then remove the connector from the vacuum port on the intake manifold.
- Remove the lower vacuum hose and pipe assembly retaining nut, and remove the assembly.
