Do not try to fill through the high pressure port.

The low pressure port is on the side of the accumulator/drier. Please rate as solved if this is what you need.

SOURCE: diagram bypass heater cord on 2001 ford expedition eddie bauer

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

SOURCE: The heater do not work in my 2001 ford expedition

sounds like your thermostat is not working (stuck closed). if the hose on top is soft after several minutes of engine running this is definitely the problem. good luck

SOURCE: 1999 FORD EXPEDITION 2WD 4.6L EGR VALVE,EGR

Remove the throttle body housing on the top of the intake, it is a 90 degree tunnel like small piece held by 4 small bolts, turn it over and look for two holes, these holes are for the EGR valve flow, they are probably plugged up with carboned crud, clean them out with the tip of a screwdriver if neccessary to remove all the crud, once its clean reinstall it and reset your check engine light, hope this helps, let me know

Where is the connection for the gages to put in freon


The high-pressure service gauge port valve is located on the A/C manifold and tube.

The low pressure service gauge port valve is located on the suction accumulator/drier

They will have caps over them that unscrew.

If your doing this with an over the counter tool you need to connect to the low side.


Hope this helped.

I need to know where the recharge port is to recharge A/C on a 1999 Ford Expedition


Your A/C system will have two service ports, there isn't any "recharge" ports. You add refrigerant to the LOW side only. Prior to adding any refrigerant, you need to check the system pressures with a manifold gauge set. If the system has enough charge and there is another issue, adding refrigerant can make for worse problems. Automotive A/C is best left to the right person with the proper equipment to service them. If you follow the lines from the compressor, the LOW side will be the smaller diameter of the two service ports.

Where is the a/c drain line location for a 1999 ford expedition?


There is no A/C drain line. The A/C refrigerant is removed or added by way of the low pressure port. The low pressure port usually has a black or blue cap with L written on the top. Find the large diameter tube leading from the compressor back to the firewall. Sometimes the port is on or near the compressor or on the accumulator neat the firewall and is not on the large diameter tube. Make sure you have the low pressure port. Connect to the high pressure port and the can may explode so make sure you have the correct port.

Low pressure hose cooling system


on my 2000 expedition it is located on top of the compressor. The compressor is barrel shapped and silver and has a belt attached to it. There are 2 ports on the air compressor, one low and one high. When charging your air conditioner the gauge will only attach to the low pressure.

A/c low pressure quick disconnect location? 1999 ford expedition


on the tube between the firewall and the a/c compressor. On some Fords the low pressure port is on the dryer2_bing.gif (aluminium cylinder). Good news is the low pressure and high pressure port are different sizes. You cannot mess it up.

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP2_bing.gif liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer back to the compressor suction

Dont know were the port is to charge my air on 1999 for expiditio


there are two lines under the hood from the compressor, the one that is located in the larger of the two lines is the charging port, you say your charging nipple doesn't fit on either? are u using R134 refridgerant charging adapters? they are very large in comparison to the older R12 refridgerent system which was phased out in 1993.
