          Step 4 of 6: Fill the system

          Done

          Fill the system with the coolant mix from the Fluids page using the cooling system filling unit tool MX-T912 until the level reaches MAX.

            Step 5 of 6: Bleed the system

            Done

            Run the engine at 2500 rpm for 4 minutes with the heater at maximum, then switch it off and let it cool. Top up to MAX only with the engine cold.

              Step 6 of 6: Pressure-test the cooling system

              Done

              With the engine cold, fit the tester adapter tool MX-T908 in place of the expansion tank cap and pressurise the system to 1.3 bar. The pressure must hold for 10 minutes, and no hose connection may leak.

              Remove the tester, refit the cap and correct the coolant level. Refit the underbody panel.
