I have been having to top up the coolant level every 2 weeks or so for the last 4 to 5 weeks, about a quart has been added each time and after a couple of weeks delay, my dealer has been able to have a look at it and has said that the radiator is leaking and needs a new one at a cost of around £450 which I assume is the fitted cost. It seems a bit expensive to me, but is it really? I don't actually know what is involved in replacing the rad on this car. Many years ago when cars were so much simpler to work on, I used to do all my own maintenance and whipping a rad out and getting it re-cored the same day was not an issue. There used to be loads of companies doing rad repairs but I have not seen one in years now.

If that is a fitted price, then that would be about right at a dealership.
The radiators 'retail' at approx. £200 from the dealers, plus costs of coolant and consumables say £50. So £200 in fitting would probably be around 2-2.5hours labour.

The parts can be obtained from a motor factors for less than £100 if you fancy having a crack at it yourself, I would probably get under the car first to eye up the job.



 

I think there was a post with pictures on here many years back.
