check where your heater is as that is where the a/c expansion valve will be and if you don't pull a vacuum on the system you could have a frozen system with possible moist air in system
why do you want to know where expansion valve is?
Look from underneath the car find the a/c lines where they go thru the body on that side of the car in the back remove the plastic trim panel to get to the rear a/c unit and some times dis-assemble the box to get to the valve
Hi Chester, I'm glad to help! The rear Expansion Valve is behind the right rear quarter panel. It mount in between the floor tubing and the evaporator tubs. Hope this helps and have an awesome day Chester.
Hi,
The expansion valve is located in the evaporator core, it is a brass made metal w/ temperature sensor tubing. Getting that expansion valve requires you to pull down the entire rear A/C blower box.
Am just curious, why are you replacing that valve?
An A/C tech will be better to do that job so that he will clean also the entire system and freon charging.
Hope that helps you out!
they will be located just before the radiator core in the cab but some american vehicles have the expansion valve inside the actual pipe its known as a reed valve or flute valve ,but in american ??? i have no idea what you would call them
The egr sensor is built onto and is part of the egr valve. Depending on what engine you have depends on where the valve is located. On 5.7 engines its in the front. On 3.7 and 4.7 its in the rear of the engine.
To install the EGR Valve on a 2005 Durango first it is necessary to remove the air intake hoses and palce them to the side. Next, in order to get the EGR valve you will need to remove the windshield wiper motor, which is a pain but necessary to do get to the EGR valve. After removing all of the itemsthat are in the way you will be faced with a task that will try your patience, the EGR valve is located on the right side of the motor, (as if you were facing the motor from the front) just behind and to the rear of the throttle body. After you locate it you will need a rachet with a flexible head because it is fairly difficult to reach otherwise. A mirror and light will also help so you can see what you are doing since the EGR valve is located in such a hard place to see and get to that you will only be able to see part of it while you are removing the screws. After removing the EGR valve, simply reversethe procedure and your done. P.S. I own a 2005 Dodge Durango SLT with a 4.7L engine and I replaced mine this year after a check engine light came on and I checked the code on the OBD. By the way the EGR valve is a pain in the rear to change. Good luck!
I am in the process of doing the same procedure on my 2001 durango 5.9... condensor, compressor, accumulator, followed by both front and rear expansion valves. I pulled the rear passenger side trim off after following the pipes to the back. It looks like the expansion vale is the first component hooked to the pipes just as they come through the body into the cabin. It appears to be wrapped in a black sticky mat... I did not unwrap yet so it may not be... What are your failure symptoms? I have a slow leak and a blockage inside the system to where it cannot be fully charged without releasing pressure from the rear of the compressor. I sure hope its not in the evaporator core...
