Engine cooling (V6)Servicing the hydraulic system
- Loosen the clamp securing the radiator outlet sleeve and disconnect the sleeve from the radiator. Drain off and collect the coolant in a suitable container placed under the vehicle.
SERVICING THE HYDRAULIC SYSTEM
- Re-connect the sleeve to the radiator along with any other hoses which were previously disconnected. Check that all the clamps are correctly tightened.
- Service until the level of the liquid reaches the MAX mark on the expansion tank. The quality and approximate quantity of the coolant are given in the table below:
| Minimum temperature | -40°C | |
|---|---|---|
| Concentrated antifreeze | Alfa Romeo Antifreeze | 5.0 litres (55%) |
| Distilled water | 4.2 litres (45%) | |
| Antifreeze ready for use | Alfa Romeo Climafuid Permanent -40°C | 9.2 litres |
- Start the engine and run to normal operating temperature so that the opening of the thermostat will vent any air trapped in the circuit.
- When the engine is cold, top-up to the MAX level marked on the expansion tank.
- Screw on and tighten the expansion tank pressurized cap.
CAUTION
Do not mix different makes of antifreeze!
Do not use rust-proofing additives as they may not be compatible with the antifreeze used in the system!
