What engine coolant have people been using in there Ro's as mine is coming up to five years old and due to be changed the manuals i have say that "Dexcool" was the factory fill brand which is an OAT type (Organic Acid Technology) whilst this type is avalible from most motor factors there seems to be lots of bad press about it sludging up cooling systems so was wondering what folks where
using and/or if they had any evidence of sludge in there system

Never seen any "sludging". We refill with genuine GM coolant.

GM stuff was around 2 quid a litre from local dealer - think it took about 12 litres in total to refill the system when I replaced the radiator. Mechanic chum told me not to bother diluting it so I filled it entirely with coolant. Think I've got a few litres spare still as I bought a couple of cases at the time - worked out cheaper to buy by the case.

to do a coolant change, is it just un clipping the bottom hose to drain

If you have an 05 car, easier to open the drain tap
