Hey scotty, I have a 2001 ford f150 with 4.2 V6 engine and standard transmission. It has 150,000 miles on it. One day i noticed a sweet smell and a mist coming out of the vents. Once I did some research it sound like the heater box is going bad. But I still have heat and I pulled up the carpet and didn't see in coolant leaking on the inside. I payed 4600 for the truck 6 months ago and it runs great. Should i spend the money to get it fixed, i can only guess the dollars signs i would be seeing from having this done sense the whole dash assembly has to be done. I am a test mechanic at a Kenworth Truck factory in Chillicothe Ohio so i could do the job, but the thing is im so busy working kenworths i dont have time to work on my ford. Thanks I love your videos and pretty much stop what im doing at the time to watch the newest one. Keep up the good work.
Can you ballpark the labor to replace one?
it's a pain in the ass, you can just bypass the heater core by splicing the heater hoses under the hood together. You will have not heat in the winter though. Here in Texas we really don't care anyway about that
