I just need some quick info to see if I can help you out.
What package does your protege have? (DS, ES, LX, or 5)
Also what engine is your vehicle equipped with?
Let me know and I will see if we can get you fixed up. Thanks.
I have a picture that will help you locate and remove the thermostat. You must first remove the fresh air duct. Drain the engine coolant. Remove the lower radiator hose and the thermostat cover. Replace the thermostat and reverse your removal procedure. Let me know if you have any other questions. Thanks.
