Well, this is the way I did it and it might seem overkill, but yer.. Keep in mind there will be coolant flowing out of everything so make sure you direct the hoses away from things you don't want wet

Remove all radiator hoses, transmission lines(if auto), etc.

Remove hose from Thermostat housing, waterpump etc.

Remove radiator, spray the cooling fins with a garden hose, then reverse flush the radiator by putting it upside down and sticking the hose in at full blast

(Now I did remove my water pump when I did this part but you don't have to unless you're replacing your water pump)

Remove thermostat housing and thermostat

Put garden hose down thermostat hole and flush it through.

Then, fit a new thermostat (Get a cooler one if you're car had overheating probs)

Put the radiator back in and hook up all the hoses, housings, pump etc.

Fill it up with coolant (if series 1, fill it up through the resevoir on the drivers side, if series 2, pour it into the radiator cap)

When it starts overflowing, start the car up and the level should drop when the thermo opens up, then keep pouring until full (not sure if you should have the car running the whole time though)

Usually you bleed the system of air while the radiator cap is off and bubbles will rise to the top. I think on series 1 you do the same but with the resevoir cap

Also, my old VP had a screw thing on the thermostat housing that would bleed the system, but I'm not sure on VN's (series 1 definitely don't have em tho)

As for a good coolant to use, I use Tectaloy Gold (something like that). You can get 1 litre for $20, which you dilute it with water to make up to 15 litres, though you only need like 10-11 but.

That pretty much covers it, If I forgot something or made a mistake, somebody can correct me, there is always someone that knows more here lol but that is pretty comprehensive when it comes to flushing the good old v6 and you shouldn't have any problems with overheating if all your parts are in good condition
