I have a 1987 GT that I am rebuilding and have taken the dash out to replace the heater core and decided to clean everything while I am in there and replace the expansion valve. I have tore out all the a/c from the dash and have been unable to find the expansion valve. Can someone tell me where it is located at as I have done a search on the computer and have looked several times and can not see it anywhere.

 

Your ac system uses an orifice tube not an expansion valve , the orifice tube is built into the hard line from the condensor to the evap(firewall). There will be ribbes in the line where its at

 

Fixed orifice tube in liquid line. Bubba
