lincoln ls thermostat housing is plastic or some crap?

What is your question?

now when these pieces fallapart, they have to clog up the coolant circulation. but where do they go. cause i replaced the thermostat housing and when i saw the worn out plastc, i said to myself this has to be the overheating problem. plastic pieces getting clogged in coolant system somewhere. but where cause i have no leak and my water pump and stuff r good. i think the plastic parts gotta be serviced every year or two. my opinion, thermostat housing and all plastic parts. cause when the plastic around the thermostat falls apart going in the coolant system somewhere cause coolant circulation problems causing overheating to occur
