How to Find the Air Conditioning Port on a 2004 Ford F-150by Allen Moore
Air conditioning service ports on the 2004 Ford F150 allow for evacuation and recharging of the air conditioning systems refrigerant, as well as vacuum testing of the system to pinpoint leaks. The 2004 F150 uses R134 refrigerant, instead of the old R-12 which Ford Motor Company phased out of its vehicle line in the 1990s. The R134 service ports are smaller than the old R-12 ports to prevent someone from introducing R-12 into an R134 system. A non-professional should not work on the air conditioning system, but a working knowledge of the system is often helpful when discussing repairs with your mechanic.
Open the hood on the 2004 Ford F150. Turn on your flashlight if you are not in a well lit area.
Look on the passenger side of the engine well until you see a large, cylindrical, black tank. This is the air conditioning receiver/drier. The tank mounts back towards the firewall and has several black aluminum lines coming out of it.
Follow the black aluminum lines that leave the receiver/drier tank forward until you come to the two red, black or blue caps protruding from the line perpendicularly. These caps cover the service ports. The purpose of the cap is to prevent contaminants from entering the service port, so make sure to reinstall them when done.

Things You'll Need
- Access to the F150
- Flashlight (optional)
- Do not attempt to recharge your own air conditioning without proper equipment and training. Without a properly functioning AC service machine, you can easily overcharge the system, which leads to leaks and/or complete system failure. Both of which are far more expensive to repair than simply paying a qualified mechanic to do it right the first time.
