I've read, never tried, that you can try to spray some WD-40 on the oring and it will help release the grip the oring has on the bore. Some people say it will pop right out if you can pull a bit and spray right on the gap. I'd thread two of the bolts in so when you finally get it it doesn't fly out and smack the radiator. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
