reading all the above posts I agree that airlocks are a pain, one problem with the Puma is the number of relatively small bore hoses in the system.
Not sure if this would work with the Puma or not but on older engines we used to clear airlocks by taking expansion cap off, turning heater on full and then driving the car for 30 mins or so, enough to heat it up and get the water circulating, with the cap off the system does not pressurise so takes longer to heat up but may work.
