• Q: How to replace the evaporator core on 2006 Chevrolet Cobalt?

You should begin by taking out the Heater Core then unsnap and open the passenger compartment filter door followed by removing the lower hvac case screws before you can remove both components along with the Evaporator core.

Set the orifice plate correctly on the Evaporator core and place it inside the hvac module assembly before seating the lower hvac case properly and tightening its screws to 1.8 n.m (15 lb in). Secure the passenger compartment filter door while inspecting the Heater Core foam seal present on the lower hvac case. If the seal shows damage, install kent industries adhesive black foam tape (P/N 46480) or equivalent to replace the seal. Install the Heater Core inside the hvac module while placing the Heater Core cover leading to final tightening of the screws to 1.8 n.m (15 lb in). Mount the hvac module back into the vehicle while performing pressurized evacuation followed by refrigerant recharging before conducting leak detection on all the fittings with the halogen leak detector (J 39400-A).
