The Orpheus tube on a 2000 Peterbilt 379 is typically located on the driver's side of the vehicle, near the firewall or the engine compartment. It is part of the air intake system and helps with monitoring air pressure. You may need to consult the vehicle's service manual for the exact positioning and any specific installation details.
The Orphus tube on a 2000 Peterbilt 379 is typically located on the driver's side of the engine compartment, near the firewall. It is connected to the air intake system and plays a role in the engine's air and fuel mixture. To access it, you may need to remove some engine covers or components for better visibility. Always refer to the vehicle's service manual for specific details and diagrams.
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.
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.
On a 1995 model Peterbilt 379, the orifice tube is typically located in the air conditioning system, specifically in the liquid line between the receiver-drier and the evaporator. To access it, you may need to remove some components to reach the line. Always refer to the vehicle's service manual for precise location and replacement procedures.
It slides into the end of the tube on the condenser.
If your talking about the orifice tube for the a/c, it is behind the grill in the a/c line on the lower left side looking at it from the front. It is located inside the line.
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.

To replace the orifice tube on a Peterbilt 379, first, locate the tube, which is typically found in the evaporator or the liquid line of the AC system. Begin by disconnecting the AC lines and removing any necessary panels to access the tube. Carefully extract the old orifice tube using a pair of pliers, then install the new tube by inserting it into the same location. Reassemble the components, ensuring all connections are secure, and recharge the AC system before testing for proper operation.
