Vectra B
Field Remedy: 1300
Remedy:Warning: Observe Safety Regulations-Air Conditioning. There are two possible cases: 1. The Air conditioning system has a pressure drop caused by an leaky hose. 2. The Air coditioning system is pressureless caused by a cracked hose. First case: - Check system pressure. - Visual check
Check air conditioning system for leaks by use of a leak
detector (only at vehicles without contrast detergent),
Check air conditioning system for leaks by use of an UV-lamp
(only at vehicles with contrast detergent).
- Drain air conditioning system. - Replace air conditioning pipe with damping rubber. - Evacuate and refill air conditioning system. Second case: - Check system pressure. - Visual check
Check air conditioning system for leaks by use of a leak
detector (only at vehicles without contrast detergent),
Check air conditioning system for leaks by use of an UV-lamp
(only at vehicles with contrast detergent).
- Drain air conditioning system. - Replace air conditioning pipe with damping rubber. - Replace receiver dryer. - Evacuate and refill air conditioning system. Working procedure: 1. Disconnect battery. 2. Check system pressure. Note: If there is only a pressure drop at the air conditioning system,
follow the instructions of the description "first case".
If the system is pressureless, follow the instructions of the
description "second case".

18. Install both upper radiator brackets. 19. Tighten refrigerant pipe at the separator point. 20. Lift vehicle. 21. Reposition damping rubber (Pic. V). 
22. Install one clamp (under coolant, Pic. VI). 
23. Fix a vacuum pipe with length of ca. 20 mm on the stud (Pic. VII). 
24. Reinstall engine compartment side cover. 25. Lower vehicle. 26. Refill air conditioning system - see working procedure "Evacuate and refill air conditioning
system", group "D", Service Instruction Vectra-B.
27. Reconnect battery. 28. Program volatile memories. Second case: 1. Check air conditioning system for leaks (only at vehicles without
contrast detergent)
- see working procedure "Leak Detection in the Refrigerant Circuit
(up to 10/98)", group "D", Service Instruction Vectra-B.
