Mike - I am now trying to get to grips with the cooling issue once and for all (see new topic on the subject). To save me the possibility of getting it wrong, what fan did you use, and how did you fit it? Also, someone mentioned to me (was it Robin) that they had fitted an electric water pump as well, with a timer. This enables you to keep the water circulating for a couple of minutes after the car is stopped so that the car doesn't then boil over. Does anyone have any idea how to fit this, and what pump to use?
It seems from people's comments that cooling is always a bit marginal, but I would like to be able to use my car next year reliably in warm parts of France so would like to deal with this once and for all.
