Coolant Fluid Level - PREVOST H3-45 VIP Owner's Manual

8-8 Care and Maintenance

COOLANT FLUID LEVEL

The coolant system has two tanks; the surge tank
(A) and the recovery tank (B).
Check the coolant level into the recovery tank (B)
when the engine is cold (room or ambient
temperature).
If the coolant level into the recovery tank is
l
lower than the MIN LINE, use the recovery
tank filler cap to add coolant until reaching the
FULL LINE.
Fill the recovery tank with the same 50/50 water-
antifreeze mixture already in the cooling system. Do
not mix two different types of coolant. Refer to the
Maintenance Manual for proper coolant type
specifications or see the label affixed near the
coolant surge tank on the vehicle.
Level Switches
Both tanks are equipped with a level switch. A
message will appear on the cluster according to
which switch is activated.
The table below shows the message and the
description.
