It would be interesting to see how many cars have suffered single and multiple radiator failures.
I have been keeping check on the coolant level and topped up about 3/4 of a litre since the swirl pot installation (7000miles). I have no signs of leakage. I will discuss when the car is in for service at the factory in February.
Is it possible to carry out an inspection of the radiator’s problem area without wings off? Maybe a boreascope? Anyhow will ask is a pressure test can be carried out. (Thanks Em)
