How to change 2003 Z4 thermostat - Help!
2003 Z4 E84, temp guage shoots to far right over-hot for a second then retrurns to normal. Engine check light is on as well. Heater only blows hot air intermittently but usually just cold even though temp setting in the cab is all the way hot. I figured it was time to replace the thermostat but have not yet done this on my Z4. Need your help, pics, videos, etc.
