First detach the retaining screw and strap from the Heater Core before removing it from the system.

Attach the Heater Core cover and place the front dash seals in the right position before tightening those screws to 1.4 n.m (12 lb in).

Install the auxiliary air distribution duct adapter as the first step before adding left and right side sound insulators. The hose clamp pliers (J 38185) should be used to reinstall heater hose clamps before putting back the fuel injector sight shield. Finally, fill the cooling system.
