Hello.My moggie is starting to overheat.I have replaced the thermostat,but it still overheats.Should I give the system a good flush out and back flush the radiator ?

Sounds like a good idea to me, certainly

Also check for oil scum in the radiator water and or water contamination of the oil (Mayo sludge on dipstick), if present head gasket leaking or cracked head/block. Also timing (too far retarded causes overheating).
Brakes binding.

Any loss of coolant? Bypass hose is coomon problem.

We need to know a bit more about your 'overheating' - ie when does it happen etc, is it leaking water? Could just be a very loose fan belt!
