The orifice tube is located on the inlet port or the primary evaporator on the passenger side of the firewall. It is nearly hidden behind/between the heater vertical hoses.
The orifice tube on a Peterbilt 379 is typically located in the expansion valve assembly of the vehicle's air conditioning system. To access it, you may need to remove the dashboard or components of the HVAC system. It's important to refer to the specific service manual for detailed instructions and diagrams, as the exact location can vary slightly depending on the configuration and model year.
Are you sure it has a fixed orifice tube system? Most heavy duty trucks use a Thermal Expansion Valve (TXV) system. In both systems, the metering device (orifice tube or TXV) is located between the condenser outlet and the evaporator inlet.
To access the orifice tube on a Peterbilt 379, first, ensure the vehicle is parked on a level surface and the engine is off. Remove the dashboard or panel covering the air conditioning components, which may require unscrewing or unclipping. The orifice tube is typically located in the liquid line of the AC system, so trace the lines from the condenser to find it, and carefully disconnect the necessary fittings to reach the tube. Always follow safety procedures and, if necessary, consult the vehicle's service manual for specific instructions.
The orifice tube is located in the line at the condenser discharge connection.

Reassemble the components, ensuring all connections are secure, and recharge the AC system before testing for proper operation.
