This is a summary of the procedure:
· remove air duct
· open service hole cover
· remove air bleed hose plug
· remove reservoir tank cap
· loosen radiator drain plug
· drain coolant
· tighten drain plug
· remove under cover
· drain radiator hose upper pipe How? As far as I could see there was no water in it after draining
· remove plug and drain coolant
· replace drain plug.
2
The air bleed hose can be found under the passenger seat.
· Set the hose in a downward position
Plug removed?
· remove filler cap
· fill coolant up to upper filling flange
With bleed plug removed water pours out so filling up to flange is not an option...
· attach filler cap
· remove reservoir filler cap.
Idle engine for approx 10 minutes then run the engine at 2,500 rpm for six
minutes. If the lower radiator hose is cold, run engine at 2,500 rpm for further
three minutes.
With plug from bleed pipe removed water shoots out and wold leave the engine dry in minutes.?
Then:
· attach air bleed hose plug
· attach filler cap
· run engine at 2,500 rpm for further five minutes
· idle engine for three minutes
· run engine at 2,500 rpm for five seconds.
Repeat this revving cycle four or five times.
Stop the engine and check the coolant level. If it seems OK,How can it be OK. it has not been topped up again? re-attach the air
bleed hose to the body of vehicle, close the service hole cover and attach the air
duct. Re-check for evidence of coolant leakage and re-attach under cover.


Has anyone successfully followed all of this and managed to bleed theirs?

Pete i am still holding out some faith here!
