Review on πŸ”§ A/C Manifold Test Gauge Kit: Boost Your Performance with the Performance Tool W89730 by Robert Gilbert

Revainrating 3 out of 5

Used this to diagnose a failed vacuum pump in one.

Used to diagnose a faulty vacuum pump in a 1985 Mercedes 300D. All I needed to know was if I was getting zero, a small amount, or a full amount of vacuum. An exact measurement was not required. It worked and it's cheap.

Pros
  • Certified
Cons
  • Some faults
