Checking Coolant Level - Scania PDE Operator's Manual

Checking coolant level

The following instructions apply to Scania ex-
pansion tanks. For other types of expansion
tanks, follow the manufacturer's instructions.
WARNING!
Never open the coolant filler cap when the en-
gine is hot. Hot coolant and steam may spray out
and cause burns.
If the cap has to be opened do it slowly and care-
fully to release the pressure before removing the
cap. Wear gloves as the coolant is still very hot.
1.
Check the coolant level through the sight
glass.
2.
Top up with coolant as necessary.
IMPORTANT!
Do not top up large quantities of coolant through
the expansion tank. Top up in accordance with
the instructions in the section headed Changing
coolant instead.
Never fill a large amount of cold coolant in a hot
engine. There is great risk of cracks forming in
the cylinder block and cylinder heads.
Only pour pre-mixed coolant into the cooling
system.
