Disconnect negative battery cable.

Remove air cleaner assembly.

Drain cooling system. On 3.1L, rotate engine forward on mounts as necessary. On all models, disconnect hoses from heater core. Remove right and left sound insulators from below instrument panel. Remove floor duct leading to rear compartment.

Remove cover and heater core. To install, reverse removal procedure.
