Where is the expansion valve on a Honda CRV?
I’m finally getting around to blogging the evaporator/expansion valve installation on our daughters ’02 Honda CRV which I performed a while back. This part is difficult to show and tell because it’s located under the passenger side dash, but I’ve included some pages out of the 02 Honda CRV service manual that may help.
How does the evaporator work on a Honda CRV?
Once the blower case and ECU have been removed, this black evaporator cover held by several Phillips screws will come off and expose the evaporator. A frustrating thing is just the wires that are in the way!
Can you put refrigerant oil in Honda evaporator?
At this time with the expansion valve off, is a good time to put a couple of ounces of refrigerant oil directly into the evaporator or see the chart up above. Re-installing is pretty much just in reverse order. It’s a little taxing to re-install the blower housing, but magically, it will go back in!
Is the AC system on a Honda CRV?
This is the Honda CRV AC system less the actual vehicle! Honda is pretty smart and takes repair into consideration I feel. The plastic part of the dash will be cut, removed, and the part discarded, I just have it propped up there to show it.

How do you replace an expansion valve on an evaporator?
Remove the bolt and the ECM/PCM bracket (A). Remove the self-tapping screws and the expansion valve cover (B). Carefully pull out the evaporator core without bending the pipes. Than you can unbolt the expansion valve from the cooling unit and replace it.
Where is the expansion valve on a Honda lorunner?
Mechanic for Honda: lorunner, Auto Service Technician replied 11 years ago Ok. the expansion valve is actually bolted to the end of the evaporater. So once you have the blower box out you than have to go and remove the expansion valve. So make sure you have the system completely empty of freon.

Why do I need to replace my expansion valve in my car?
AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system. Diagnosing your car’s air conditioning system may reveal that your expansion valve or the orifice tube needs to be replaced.
Where is the a / C expansion valve located in a car?
The A/C expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system.
Why does my air conditioner have an expansion valve?
If your air conditioning (AC) has been less than helpful this summer, it may be the expansion valve (also known as an orifice tube). AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system.
AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system. Diagnosing your car’s air conditioning system may reveal that your expansion valve or the orifice tube needs to be replaced.
Do you have to replace the evaporator coil on a Honda CRV?
Yes, the dash does have to come out to replace the evaporator. Directions are below: Remove the instrument panel by performing the following procedure: Remove the driver-s side lower instrument panel cover screws, disengage the clips and remove the lower cover. Remove the knee bolster bolts and the knee bolster.
How do you know if an air conditioner expansion valve is recoverable?
Step 1: Identify the refrigerant. Using the service manual, locate the low pressure fitting of the two AC service fittings on the car and connect the refrigerant identifier to the car. The refrigerant identifier will take a small sample of the refrigerant in the system and tell you if it is recoverable or not.
Can a bad or failing expansion valve cause unmetered refrigerant?
Frost on AC evaporator or coming from the vents. Another symptom of a potential problem with the vehicle’s AC expansion valve or orifice tube is frost coming from the vehicle’s vents. If the AC evaporator or orifice tube malfunctions, it can cause refrigerant to flow unmetered through the vehicle’s AC system.
Is the expansion valve the same as the evaporator?
The new expansion valve was identical to the OEM. The only thing, I had to tweak the new evaporator hard lines to match the old one. It’s a precise fit for the expansion valve to reside in its little home in the firewall!;)
How much does it cost to replace an expansion valve on a Honda CRV?
Honda CR-V Expansion Valve (Orifice Tube) Replacement costs $437 on average. Following is a breakdown of the labor and parts estimates. What is the Expansion Valve (Orifice Tube) all about? The air conditioning system in your vehicle depends on the refrigerant that circulates in the A/C system.
Where is the expansion valve on a car?
Average rating from 5 customers who received a Check Heating AC. An expansion valve is an AC component that is commonly found on many road going vehicles. It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the vehicle’s AC system.
Where is the expansion valve on a Honda evaporator?
It’s a precise fit for the expansion valve to reside in its little home in the firewall!;) At this time with the expansion valve off, is a good time to put a couple of ounces of refrigerant oil directly into the evaporator or see the chart up above. Re-installing is pretty much just in reverse order.
What happens when your a / C expansion valve goes bad?
You will notice when the A/C expansion valve goes bad because your air conditioning system will ultimately stop functioning properly. It will either produce less cool air or it won’t produce any cool air at all. At this point, you will need to replace your A/C expansion valve to fix the problem.
How do you replace an expansion valve on a car?
Under the hood at the passenger firewall you will see the 2 cooling pipes go into the firewall. Unbolt those pipes. than under the dash follow these steps. Remove the bolt and the ECM/PCM bracket (A). Remove the self-tapping screws and the expansion valve cover (B). Carefully pull out the evaporator core without bending the pipes.

What happens if there is too much refrigerant in a Honda CRV?
Too much refrigerant will cause frost on the core and prevent air from passing through to cool the air temperature. Too little refrigerant passing through the evaporator means not enough heat is absorbed and the interior is insufficiently cooled.

How to tell if an expansion valve is bad?
Symptoms of a Bad or Failing Expansion Valve (Orifice Tube) 1 AC system performing worse than usual and blowing warm air. 2 Frost on AC evaporator or coming from the vents. 3 AC compressor constantly running.
Can a bad expansion valve cause an AC compressor to run?
AC compressor constantly running. A constantly running compressor is another symptom of a possible problem with the AC expansion valve. If the AC expansion valve fails or sticks open, it will cause the compressor to pump refrigerant through the vehicle’s AC system, even when it may be undesirable for it to do so.

Where is the expansion valve on an AC unit?
The AC expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Whenever there is an abundance of refrigerant, the core of the evaporator will get too cold and eventually freeze.
What are the symptoms of a bad a / C expansion valve?
The most recognizable symptom of a bad A/C expansion valve is when you turn on your air conditioner and warm air starts blowing out of the vents. This would obviously mean that not enough refrigerant is making its way to the core of the evaporator.
