  8. Install a measuring container (1) on the filler of the cooling system reservoir.
  9. Fill the cooling system with prescribed coolant until fluid is coming out of the bleed screws and tighten the bleed screws. Refer to CAPACITIES AND RECOMMENDED FLUIDS, SPECIFICATIONS .
  10. Continue filling until the fluid reaches about 1/3 of the height of the measuring container previously fitted on the cooling system reservoir.
  11. At this point, the level in the reservoir will be flush with the filler:
    1. - Start up the engine and let it idle for about two minutes.
    2. - Remove the air from the circuit by pumping the accelerator regularly and gradually (every 30 secs) up to a
    3. speed of around 2500 rpm. This operation must be carried out so that the thermostat opens and the fan
    4. switches on and off at least 3 times. - During this operation, keep the climate control system switched off to
    5. prevent the fan coming on not due to the heating of the coolant.
    6. If there is a noticeable level drop in the expansion tank during this step, switch off the engine, open the cap
    7. very carefully and top up the fluid to the MAX mark; then close the cap fully and complete bleeding the air
    8. from the system with the engine running.
    9. - Switch off the engine.
    10. - After allowing the engine to cool, check that the fluid level is at the MAX mark on the expansion tank.
  12. Switch off the engine, remove the measuring container and install the engine cooling system reservoir cap.
  13. Install the engine belly pan. Refer to BELLY PAN, ENGINE, REMOVAL AND INSTALLATION .
