Got a 2003 Xsara saloon 1.4 a couple of months back, and it's generally been very good, nice drive, incredibly quiet, and not half bad fuel consumption for quite a big petrol car, One problem that has turned up recently is a leak in the passenger side footwell of some red rusty water, From your very helpful forum, it seems that it's likely to be the heat exchanger with a pin hole leak (it isn't a big leak) and I was recommended to use Forte Stopleak (rather than Radweld and the like) The mystery is, no where on the Forte site, nor the bottle itself or online can I find any instructions how to use this stuff correctly, but lots of statements saying to make sure it's used 'as instructed'! Any advice on how to use this Forte Stopleak? Thanks, All the best, Ioan,
