Incorporation of additional heater into coolant circuit
Bleeding coolant circuit
-
‒ Bleed engine coolant circuit as specified.
=> Relevant Engine Workshop Manual, Mechanical components; Repair group 19; Cooling system
-
‒ Once engine has reached operating temperature:
-
‒ Set air conditioner or heating system to maximum heat output (e.g. temperature preselection "Hi").
Notes:
-
◆ The additional heater is currently installed without a recirculating pump. The coolant is pumped through the additional heater only by means of the engine coolant pump.
-
◆ It is not necessary to switch on the additional heater for bleeding as there is a constant flow through it.
-
‒ Top up coolant if necessary.
