new coolant.

1. Expansion tank
2. Cold fluid level sign
1. Stop the engine and let it stand for a few minutes.
The checking must be made when the fluid is cold. A hot fluid level is higher
than a cold.
2. Check that the fluid level in the expansion tank is in accordance with the fluid
level sign for cold fluid.
3. Add more coolant to the tank, if necessary.
IMPORTANT: Never use just water as coolant.
• Check the freezing point of the coolant.
At the beginning of the cold season it is important to measure the
freezing point.
• If the freezing point is too high, drain off some of the coolant and top up
with anti-freeze.
• Run the engine for a while.
The anti-freeze must be mixed with the coolant.
• Re-check the freezing point of the coolant.
4. Inspect the expansion tank for leakage.
IMPORTANT: There is a drain hole under the water pump that must not be
blocked. If coolant drips out of the hole, the pump seal is damaged and must
be replaced. In a new engine some leakage is possible until the pump settles
in.
