Coolant: Service and Repair
Coolant Circuit, Bleeding
Coolant Circuit, Bleeding
NOTE:
-
The removal of A/C system components (except for compressor in vehicles with 8 cyl. engine) is described in this Repair Information in such a
way that only a small amount of air enters the coolant circuit, therefore it is not necessary to bleed coolant circuit completely after removing and
installing these components.
-
If, however, a large amount of coolant flows out due to a different complaint, e.g. due to a leaking hose, compressor replacement on vehicles with
8 cyl. engine or after coolant hose replacement, the coolant circuit is to be bled completely using Kent-Moore ACR(4) refrigerant
recovery/recycling/recharging unit (or equivalent).
-
After bleeding and charging the coolant circuit using Kent-Moore ACR(4) refrigerant recovery/recycling/recharging unit (or equivalent), the
section of the coolant circuit with the A/C system (heater core and associated hoses) is to be post-bled as described below.
