bleed the bleeding system?

Fill with coolant, run car, check for leaks while running. Keep car running whilst filling it up with coolant until thermostat and cooling fans kick in, put radiator cap back on.

and make sure you have cleaned out the reservoir for the coolant, filled it up, and keep an eye on its level as any air trapped in the system will appear there and the level may drop over the next few weeks.

ok thanks for that

Is farily simple, fill up until when slowly pouring in coolant and water you reach the top in the radiator. Start the motor and let idle. once the motor warms up the level will drop a little as the thermostat chages from bypass to allowing the coolant to flow to the radiator.

Once it gets up to running temp, leave cap off and let motor cool, top up and put on cap

Once you have had the first drive, is a good idea to check the res and the rad once the motor is completely cool again
