I have a 2000 f150 with a v8 4.6 when I turned on my ac there is a smell like antifreeze coming out. It pretty bad to wear I can't use it. Checked coolant and level is fine. And truck is not over heating. Any ideas.

 

Sounds like a heater core leak.

 

^^ this would be my suspicion.

 

Is that hard to change out and is it expensive

 

Yep dash has to be pulled, I assume like others. Sell it!

 

7000.00 want to buy it.

 

Nope want to buy my 13 with poor ac?

 

Same thing is happening to my 01. Vapors blew out while using a/c as well. Keep an eye on the fluid, if you don't use any vent controls, fluid should be fine. Heater core is not expensive from what I heard, it's the labor that cost so much. It is very involved from the videos I have watched on youtube. Having a mechanic friend come by the house on a Sunday to help pull the dash. Understand the job is booked for 10 hrs labor. Hoping he lets me off easy. Have a son that needs a vechile! Time for me to invest in something newer. Good Luck.
