Volvo 1990 780 Model
WARNING! The oil may be very
hot
Do not use rags that could leave lint on the dipstick.
The transmission is topped up via the dipstick tube.
The space between the MIN and MAX marks on the dipstick corresponds to 0.5 US qt (0.5 liter). Do not fill the transmission
with too much oil, since this can result in oil being ejected from the transmission.
Too little oil, on the other hand, can negatively affect transmission operation, particularly in very cold weather.
pg. 103 Cooling system
Check coolant level
The cooling system must be filled with coolant and not leak to operate at maximum efficiency. Check the coolant level when
filling fuel. The level should be between the "Max" and "Min" marks on the expansion tank. The check should be made with
particular thoroughness when the engine is new or when the cooling system has been drained.
Do not remove the filler cap other than for topping-up with coolant. Frequent removal may prevent coolant circulations
between the engine tank during engine warm-up and cooling.
Changing coolant
Every two years or 30000 miles (48,000 km) the cooling system should be drained, flushed and refilled.
Remove the expansion tank cap. Open the drain cock on the right side of the engine block and disconnect the lower radiator
hose.
Fill coolant through the expansion tank. The heater controls should be fully open when draining and filling.
Add coolant until the level is up to the MAX mark or slightly above.
