Your problem could stem from various sources: the thermostat may be stuck, the system may be plugged, the fans may not work, or the engine head gasket may be blown.

I recommend having a mechanic, such as one from YourMechanic, run a diagnostic test for your overheating issue, and recommend the best path to repair.
