Two weeks have gone now and its lost about half a pint.
I ran my finger underneath the hose from the top of the radiator to the engine block and where it goes onto the block I ran my finger under and there was quite a few drops under there and it had been dripping (slowly onto the alternator is it? underneath this pipe so this would also explain why i wasnt seeing it on the drive. Also on the plastic guards under the alternator are always wet im not sure this is from oil or water but oil would dry up eventually?
Anyway, I have tightened the jubilee and stuck another jubilee next to that one, when I undid the jubilee clip about a turn it started dripping out quite fast so maybe under pressure and over time it was dripping out of this point? I'm hoping two tight jubilees will solve the problem.
I also checked out my radiator and it looks quite battered on the front of it on the drivers side a few holes in it, could it leak from there also? Think I might need a new radiator how much is it for one?
Also I have a lot of dried white splashes on my rocker cover directly back from where the radiator cap is, I bought one of those nismo radiator cap jobbies off ebay, could this be leaking under pressure also?
