how to change a expantion valve on a 2000 honda civic.?

Question

I have the fan motor and plastic cage out. But I cannot get the back screws out of the back of the evaperator cage out.

Answer 1

after the refrigerant is reclaimed you disconnect the large and small pipes at the firewall under the hood [the battery and tray will have to come out for access] remove glove box and you will see 5 bolts with 10mm hex heads [4 gold looking and 1 or 2 black ] remove these and the evaporator case will come out [the expansion valve is inside] so open the case [clips and screws] being mindful of the seal strips cut them with a razor where the case separates you can now access the valve, use new o-rings at all joints and don't forget to replace the dryer [up front near and below the power steering reservoir] re assembly is the reverse of above noting that a dab of black silicone at the evap case seals will prevent annoying whistles.
