Leak Detection

1. Tighten the manifold retaining bolt to 18-23 Nm (13-17 ft lb).
2. Add refrigerant to the system if necessary.
3. Leak test the manifold O-ring seals using Rotunda R-134a Automatic Calibration Halogen Leak Detector 023-R1003 or equivalent.
4. If no leaks are found, the manifold O-ring seals are good.
5. If a leak is found at the manifold and the manifold bolt is tightened to 18-23 Nm (13-17 ft lb), install new manifold O-ring seals. Repeat the leak test.
