8.9 Cooling system
Roberine recommends the following coolant:
• Havoline AFC + B 50/50 (BL01)
If the recommended coolant is not available, use a low silicate ethylene glycol base coolant concentrate in a 50% mixture
of concentrate with quality water. This provides freeze protection to -37 °C.
Use a coolant with a conditioner or add conditioner before use.
In certain regions, protection against lower temperatures may be required. Read the label on the coolant packaging or
contact your authorised service centre for the most recent information and recommendations
