Hey just read your novel lol!! I can tell you everything you need to know, however i am at work right now, but will b off here in about an hour or so!! I went through this exact same thing trying to find info on flushing the radiator on my gtp, and never really found anything, however a local gp memeber and i tackled it and figured it out, and also took pics for this very reason just havent posted them yet!! But when i get home and settled i will hit you back and fill you in![]()
