cheers for reply david
she is due in for a full pad and disc change this month (cant really complain, 6 years and this is the first work on the brakes) so will try and find some extra cash for new rad next month. on another point, have you had any experience of aftermarket exausts? 2 years ago I had to get a full system replaced (sensor went and each section blew one after the other) since then I have had no end of problems, with the centre box now about to be replaced for the third time on the guarentee - give up and go stainless?
