Refrigerant
Parking heater
• Check that the combustion air and exhaust openings
are not blocked
• Check that the heater fuel pipes are carefully
installed and clamped
• To avoid harmful deposits, the heater should be
started once a month, even in summer, and should
then be allowed to run for 15 minutes. Do not
forget to set the thermostat and heat controls
• When the coolant is changed or topped up, the
engine must be warmed up until the thermostat
opens and the cooling system has been vented
before the heater can be started. If the heater is
started too early, there is a risk that the overheating
guard in the heater could be tripped
• Perform and annual check of the heater in good
time before the winter season starts. Contact your
Volvo workshop
