Its leaking from the circled area in the photo and it sprays up while driving, enough to leave noticeable amounts underneath the bonnet.
When I fitted the front extractors I had trouble putting the radiator back in, the metal bracket bit on the back of the fans was jamming up against the furthest pipe on the header.. I ended up just forcing it down into place and it fitted.. But it stil just sits against the header pipe, which was obviously putting pressure on the radiator and combined with a heap of hot coolant pressure has caused it to split at the top. does that sound about right??
I've got another radiator ready to go in, but I'm obviously going to have the same problem.. ..

Has anyone else had issues with the extractor sticking to too far out? Thinking I can probably just grind it down a few mil... Or What else???
