Have just changed the thermostat on my PD130, used genuine part and O-ring.
Naturally lost abit of coolant in the process.

Whats the best process to bleed the system?

Do you run it upto temp with the cap off the expansion bottle (which takes friggin ages)
or do you just slap some extra coolant in the expansion bottle and go for a drive??

fill up the cooling system to the mark on the expansion tank set heat temp to max take car for a short run where you usually get it up to temp when it gets up to temp stop the car leave engine running and check your coolant level if it needs topping up turn of engine wait about 5mins slowly open expansion cap pour in extra antifreeze if needed while squeezing pipes and watching for air bubbles put cap back on and check to see if heaters are giving out heat turn on blowers to check heater temp does not drop. then lift bonnet and wait for cooling fans to cycle running twice. checking temp gauge and expansion tank car should be good to go.
