## Heater Pipe and Hose Component Installation Note

• Insert the heater pipe into the heater hose until the hose reaches the bracket or the protrusion on the pipe.

• When the rear heater pipe is removed, bleed the air from the rear heater pipe thoroughly after refilling the engine coolant to prevent air from being trapped in the rear heater pipe.
• Install the rear heater pipe and rear cooler pipe securely as shown.
