22.6 Maintenance cooling system (engine)
Risk of fire from anti-freeze!
If anti-freeze comes into contact with hot components in the warm engine compartment, it may
ignite. There is a risk of fire and injuries.
• Leave the engine to cool down before filling with anti-freeze.
• Keep anti-freeze away from the filler neck.
• Before starting the engine, thoroughly clean components contaminated with anti-freeze.
Danger of injury due to scalding!
The engine cooling system is under pressure, especially when the engine is warm. If the cover
is opened when the engine is warm, hot coolant may spray out. There is risk of injury.
• Leave the engine to cool down before opening the cover.
• When opening the cover, wear suitable gloves and goggles.
• To relieve the pressure, open the cover by a half turn.
22.6.1 Coolant
NOTE
The stipulated coolants are listed in the chap. "Technical data" Consumables!
The engine cooling system is filled ex works with corrosion-inhibiting frost protection
agent/water. The coolant consists of 50% corrosion protection and frost protection agent and
50% water. The anti-freeze safety feature is guaranteed up to approx. -37°C.
Before the beginning of winter, always check the consistency of the anti-freeze.
If no coolant is available, then depending on the season, you should use a mixture of 50%
ethylene glycol antifreeze/anti-corrosion agent and 50% clear, soft water. This mixture also
offers corrosion protection and protection against freezing to -37°C.
NOTE
Cooling system density additives may not be used.
