How to remove the air conditioning Evaporator?

To remove the air conditioning system, start by discharging the system and disconnecting the battery cable. Then, drain the cooling system and disconnect the air conditioning lines from the blower/evaporator housing. Remove the wiring connector at the blower motor resistor and the large wiring bundle clip. Take out the computer and coolant recovery tank, and move the relay mounting bracket. Remove the housing mounting nuts and bolts, and pull the housing forward to break the seal and remove it. Separate the upper and lower halves of the housing, and remove the condenser. Check the core for leaks and straighten any bent fins. If installing a new evaporator core, transfer the sealing gaskets. For installation, refill the cooling system and use new R-134a-compatible o-rings. Ensure the foam gasket is in place when reinstalling the housing. If a new evaporator is installed, add refrigerant oil and have the system evacuated, recharged, and leak tested.

GMC Sonoma Evaporator

The Evaporator on GMC Sonoma automobiles is part of the A/C system and consists of the condenser, valve, and the evaporator which changes liquid refrigeration into vapor through the process of impressing and evac'ing the vehicle interior. Residing under the hood along the heater core, the evaporator is made of aluminum tubes with fins that resemble those in the condenser; it goes then to the refrigerant and absorbs heat from the air. Furthermore, through the refrigeration cycle the evaporator also takes on the function of a dehumidifier since it also helps to remove moisture from the air. A component that is frequently changed out because of cracks resulting from using or exposure to heat, cold or debris, the A/C Evaporator is essential to maintaining the inside of the car adequately cool while operating.

Each OEM GMC Sonoma Evaporator we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
