Just completed a 100 mile day trip and when I got back found I had lost about 1/2 litre of water. Not a major problem but I would still like to fix it.
So I used a hi-tech solution to find the leak. And after running the engine in the garage for 15 mins it is obvious the leak is in the are of the bottom hose on the radiator.
I tightened up the hose again but I will probably put a slug of Radweld in to see what happens.
