Start by disconnecting both heater hoses at the Heater Core before moving to the removal of the lower floor console when present and then the lh and rh instrument panel insulators.

Subsequently you can remove the screws followed by the outlet cover itself.

Secure the Heater Core line clamp screw at 1.5 n.m (13 lb in) torque while installing the Heater Core mounting clip along with its screw, tightening it to 1.5 n.m (13 lb in). Begin by attaching the outer seal to the Heater Core and then securing the new seals (1, 2, 3) on the Heater Core cover before installing the cover with its screws that need to be tightened to 1.5 n.m (13 lb in). Screw and attach the Heater Core outlet cover before tightening its screws to 1.5 n.m (13 lb in).
