overheating problem

[Slug172]

Been loosing water I've put 'rad weld' in the water and it seems to have cured the problem how long will it last?

Not very long, radweld also makes a gooey mess of everything. If its the radiator they are fairly straight forward to change and can be bought from places like adrad.co.uk for about £70.

Did you undo the top hose on the rad and pour the rad weld in from there??
