Thanks guys,
How do I go about draining all the coolant? Is there a plug at the bottom of the radiator?
Also the pipes to the matrix, are they difficult to replace/possible to reach? Doesn't look like there is much room there!
Anyway I ordered the valve, £31 delivered from euro car parts, not too bad, but still bites slightly when I wasn't told about the issue - still chasing the seller up!
Fingers crossed I will get it this week, so next weekend I can change it
Cheers,
