The replacement parts are supplied as separate kits containing multiple piece lines for ease of installation.
- The following procedure can be used to remove and install one of, or both the auxiliary heater inlet line and auxiliary heater outlet line. If only one auxiliary heater line is to be removed and installed, cut or disconnect only the desired line at the specified points within the procedure.
1. Drain the engine coolant.
2. Remove the RH quarter trim panel.
3. Detach the auxiliary heater lines.
