Not yet. Last week the drop in temperature made the rad leak overnight. Not noticed until half way to Sidari and then the 'ole stop light on dashboard flashes.
Got home and plugged the hole with "gripfill" It's been ok ever since. It will have to be changed for the next service though because, unfortunately. there is now, no way the water can be drained without removing the sealant and old plug.
(73 years old and and more boring than ever!!!!!!)
And still too tight to buy a new rad.
