i wouldnt bother, while the coolant is still green, just drop what you can and refill.

then maybe re-rod the radiator once every 5 years.

Guys..

Is there a simple way of just dropping the fluid and topping back up again ?

Drop bottom hose.

Run fresh water through the bottom hose of radiator with top hose off - high tap pressure and seal outlet with hand around garden hose.

refit hoses and refill with fresh coolant.

similar to a reverse pressure flush without the air/water pressure - dont rate that part anyway.

ill give that a shot, im not very mechanically minded....

Was there a trick to filling again ?? think i read somewhere was better to have the car on a slope ? for air pockets etc

Will do just that.

Jester also added to have the heater on full ? is that while refilling or while dropping the fluid also ?

While re-filling

get as much as you can in thru top header get car started then keep topping it up with screw on top off on header tank (you dont want it to pressurise) keep ya eye on temp gauge oh and keep heater on full whack in car

then when you think its full which it wont be let the car cool down top up again and do the same again...

probably not the pro's way of doing it but i have dones loads of em and they are all ok afterwards

Follow this instructions and you wont go wrong
