 Danger !

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

 Danger !

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.
Wear protective gloves, protective clothing and safety glasses.

Notes on coolant

AH20.00-N-2080-01A



Check

1

Turn cap (1) of coolant expansion reservoir (2) slowly in order to reduce overpressure in cooling system

2

Check composition of anticorrosion or antifreeze

In case the antifreeze content is too low:



Open drain screw (3) and drain a little coolant into container. Then tighten drain screw (3). Correct corrosion and antifreeze protection, subject to separate repair order

3

Check coolant level

 Check and correct the coolant level only when the coolant temperature is below 50 °C.

 MODEL 405.10/12/20/22
The cooling system is correctly filled when the coolant level is level with the lower edge of the filler opening of the coolant expansion reservoir (2).

 MODEL 405.050
The cooling system is correctly filled when the coolant level is level with the MAX. mark on the coolant expansion reservoir (2).

4

Adjust coolant to correct level

 MODEL 405.10/12/20/22
Add coolant up to the lower edge of filler opening of coolant expansion reservoir (2). Use only coolant of the specified composition.

 MODEL 405.050
Add coolant up to "MAX" mark in coolant expansion reservoir (2). Use only coolant of the specified composition.
