Special tools and workshop equipment required
- Cooling System Charge Kit :VAS6096
- Cooling System Tester - Adapter :VAG1274/10
- Cooling System Tester - Adapter :VAG1274/8
- The removal of A/C system components is described in this repair manual in such a way that only a small amount of air enters the coolant circuit. Therefore, it is not necessary to bleed the coolant circuit completely after removing and installing these components.
- However, if a large quantity of coolant has escaped due to another concern, for example, due to a leaking hose, the coolant circuit must be completely bled with the :VAS6096 . Refer to COOLANT, DRAINING AND FILLING [For engine(s) CTGE, CEUC] or COOLANT, DRAINING AND FILLING [For engine(s) CPNB] or COOLANT, DRAINING AND FILLING [For engine(s) CREC, CREH] or COOLANT, DRAINING AND FILLING [For transmission(s) 0B5, 0CK] [For engine(s) CYNB] .
- After bleeding and charging the coolant circuit using the :VAS6096
, the section of the coolant circuit of the A/C system (heater core and associated hoses) is to be post-bled again via the bleed hole -arrow-.
