INSPECTION AFTER REMOVAL

Appearance
Check for correct assembly, damage and deterioration.

Check Valve Airtightness Use a handy vacuum pump (A) to check.

When connected to the booster side (B): Vacuum should decrease within 1.3 kPa (9.8 mmHg, 0.38 inHg, 0.013 bar) for 15 seconds under a vacuum of −66.7 kPa (−500 mmHg, −19.70 inHg, −0.667 bar).

When connected to the engine side (C): Vacuum should not exist.

Replace vacuum hose if vacuum hose is malfunctioning.
