Hey guys on my '96 Cobra the thermostat stuck closed on me and when I took it out I found a broken piece of black plastic about 1 1/4" by 3/4" down by the thermostat. Any ideas where it could have come from? I'm in the process of taking all the coolant hoses off and flushing out the system right now, my coolant is crystal clear and I havent found anything else in there yet but it is bugging me that I found this and I want to make sure nothing else is wrong.:cuss:
