1999 Ford F150 V8 Four Wheel Drive Automatic 185000 miles
I own a f-150 4x4 5.4L, 185000 miles. A few months ago my service engine light came on. My mechanic said it was more than likely a sensor that went out because my truck wasn't running any different. Two weeks ago, my heater quit working. Now, last night I noticed a strong coolant smell in my cab, and when I turn on the air the smell gets stronger. My truck is running fine no problems other than the coolant smell an the fact Im freezing to death with no heater. My biggest concern is, IS IT SAFE TO DRIVE?
