Coolant System - NC HT1.0 Original Instructions Manual

CHECKING COOLANT LEVEL
Always check the coolant level when engine is cold
This is a pressurised cooling system
To prevent scalding NEVER remove the filler cap when the coolant is hot
Hot coolant will burn you. Always check the engine is cool before checking
the coolant level or draining the system.
When the engine is cold if the coolant level is below
•
the minimum level on the bottle (A), remove the filler
cap (B) and add coolant until the coolant is just below
the maximum level line
Replace the expansion tank filler cap (B).
•
DRAINING THE COOLING SYSTEM
Ensure the engine is cold carefully undo the pressure
•
cap (C) on the radiator to release any built up pressure
escape, Remove the cap when all the pressure is
released.
Open both drain cocks one on engine (D) and one on
•
the radiator (E).
Allow the coolant to drain into a suitable container.
•
Flush the system by pouring clean water into the
•
radiator filler neck.
Screw closed both drain cocks.
•
Dispose of used coolant in an environmentally safe way
REFILLING THE COOLING SYSTEM
Ensure the engine is cold.
•
Remove the radiator cap and add coolant mix to just
•
below the top of the filler neck on the radiator,
allowing time for the coolant to settle as necessary.
Replace the filler cap. (see Fluids & Lubricants
section regarding coolant mix).
Start the engine and allow it to run for approximately
•
2 minutes. This will also fill the expansion bottle as
the core finds its desired level.
With the engine stopped and the cool, remove the
•
filler cap (B) and top up as necessary to just below
the max mark. Repeat the above process and toping
up again until the level remains steady. This will
ensure all the air has been expelled from the system.
