Hey guys!
New to being a member but I've visited the site before for help. I posted in audi models s4 regarding a leaky radiator. I found a crack in the plastic that surrounds the radiator and it appears to the source of the leak. Is this the forum that I should post that question into? Any help would be appreciated! Below is a picture of the crack. Wanted to know if I should attempt a seal or replace completely. Not sure of the pressure build up that surrounds the area. Thanks,
Adam
