I replaced the spark plugs on my 97 f250 4.6. Not sure but must have cracked the heater core inlet or outlet as the first ride after I had coolant in my defroster. How does the heater core come out?
Your heater core comes out through the fire wall on the passenger side. There are two hoses that connect to it. Are you seeing any sign of damage there and are you sure your sparkplug work did that?
