Hi,It is not to difficult to remove or replace the expansion value for your Honda cars. Only you have to do to replace or remove the components. You have to disconnect the two lines to the evaporator from the engine bay, then you will have to remove the evaporator unit from under the passenger's dash. Then you take apart the evaporator to get to the expansion valve.
Here's I have also attached the video of expansion valve replacement of your Honda Accord.
Shouldn't have an expansion valve. There should be an orifice tobe in the refrigeration line before it enters evaporator usually near firewall. Just my opinion.
If it sounds kind of like a sewing machine when you try and start it, the timing belt has probably broken and the cylinder head may have to come to replace bent valves before a new belt can be put on. This is unfortunately a common problem on older Hondas if the belt is not changed on time.
expansion valve is located inside evaporator box behinde glove box you will need to evac system and recharge if going to replcace...this job is not for the first time mechanic
Do you have good vacuum at the PCV valve? Remove your spark plugs and run a compression test. Sounds like you have a lot of blow by. Combustion gases blowing by the piston rings.
Hi Tresap,
The only expansion valve that I can think of that you may like to replace is on the air conditioning unit....This valve is found usualy mounted onto the AC unit....You'll have to remove the dash board and centre consul....This is qute a job....You should then see the expantion valve on the cabin side of the AC housing....where the pipes go thru into the engine compartment....NOW HOLD EVERYTHING.....before you can remove the valve you need to depressurize the AC unit....That should be done by an expert....The gas is dangerous and you must wear safety googles at ALL times....Once you have removed the valve, you must seal the system so that as little moisture as possible enters the system....If it is left open, you'll have to replace the dryer unit too....when you've finished your replacement, assembly is the opposite as disassembly.....You'll then need to have the system recharged....Don't try to engage it until that has been done....It wont work even if you tried ,as there are pressur switches which will inhibit the opperation....If you have had practice, it will take about three quarters of a day......if not, three or four days
