I must admit, I am not a Forum savvy kinda guy. I did not have much luck finding what I was looking for. I have a 2004 S & S M1079 (LMTV) that runs hot and shuts itself down. I replaced the coolant and when I did there were small pieces of red plastic in the coolant. About 6 pieces of all different sizes about 1/16" thick. Is there something internal (maybe a fan), that may have deteriorated? I have no idea what they were or where they came from. Any help/suggestions would be appreciated.
