Where is the orifice tube on a 2007 Honda CRV?
The 2007 Honda CR‑V does not have a separate orifice tube you can locate or service under the hood. Instead, the A/C system uses a thermostatic expansion valve (TXV) inside the evaporator housing behind the dashboard.
The metering device for this model is integrated into the evaporator assembly in the dash, so the orifice tube is not accessible as a standalone component. The evaporator housing sits behind the glove box area, against the firewall on the passenger side.
Understanding the A/C expansion device in the CR‑V
In this generation, Honda uses an expansion valve to control refrigerant flow into the evaporator. Unlike vehicles with a fixed orifice tube in the engine bay, the CR‑V’s TXV sits inside the evaporator housing and regulates flow based on evaporator temperature. This design means there isn’t a separate, user-accessible orifice tube to inspect or replace.
Where the TXV is located and how it’s accessed
The TXV is inside the evaporator unit within the HVAC housing on the passenger side of the dash. Access typically requires removing interior panels, including the glove box area, rather than opening the engine compartment. Because the valve is inside the dash, service involves interior disassembly and proper refrigerant handling.
Notes for maintenance and repairs
If you’re troubleshooting cooling performance or leaks, it’s best handled by a qualified A/C technician. They will measure system pressures, check for refrigerant leaks, and perform evacuation and recharge with the correct R‑134a specification. There is no separate, removable orifice tube to replace on this model.
Summary
For a 2007 Honda CR‑V, there is no discrete orifice tube located under the hood. The system uses a thermostatic expansion valve integrated into the evaporator housing behind the dash, with access requiring interior dash work rather than engine‑bay inspection.
