OPERATION
Coolant Level
DO NOT remove the radiator pressure cap (6), illust. Z22468
from a hot engine. Wait until the temperature is below 50°C
before removing the pressure cap (6). Failure to do so can
result in personal injury from heated coolant spray or steam.
Press the red button on the radiator pressure cap to allow
the pressure to escape. Turn the radiator cap slowly counter-
clockwise to the safety stop, then continue to turn until cap
is free to be removed.
The coolant level should be in the upper field of the sight gauges
(4). If necessary add coolant via the swing down service arm to
the MAX marking on the sight gauge. Refer to section "CENTRAL
REFILLING SYSTEM" on page 286 for more information.

tion and filling procedure.
