I have a slow, mysterious antifreeze leak and I cant find where its coming from. I have come to the conclusion that it is NOT a valve cover leak, head gasket leak, water pump leak, or any coolant lines. The overfill bottle is always empty, and I am putting antifreeze directly into the radiator once a week. My temp gauge fluctuates from the N in normal to in between the R and M. Are plastic radiators known for leaking over time? How much does a new one cost? Any help would appreciated.
Thanks, Jason
