• The pump of the -VAS 531 007- must be switched on.
– Slowly open shut-off tap -A-.
• The vacuum in the cooling system causes the distilled water
to be drawn into the cooling system, and thus causes the cool‐
ing system to be filled. In addition, the pump of the -VAS 531
007- feeds distilled water into the coolant expansion tank.
– Fill cooling system until pressure of approx. 1 bar can be read
off gauge.
After filling, the pressure in the coolant expansion tank must be
released. Proceed as follows to do this:
– Close shut-off tap -A- after filling.
– Remove suction-jet pump -2- from valve block -1- .
– Connect drain hose -arrow- to plug-in connector. Open shut-
off tap -B-, and leave it open so that the pressure in the cooling
system releases.
– Remove air filter housing
– With ignition switched off, release and pull off electrical con‐
nector -1- on engine temperature sender - G62- -3-.
Note
If the connector of the coolant temperature sender - G62- is pulled
off, the actuator for engine temperature regulation - N493- will
open and the radiator fan will start to operate as soon as the en‐
gine is started.
– Temporarily, install air filter housing so that corresponding lo‐
cation on cylinder head remains free. Air filter housing can be
placed on battery, for example.
– Start engine and increase speed for approximately 1 minute.
Then, switch off engine.
