Evaporator Installation Guide

The following is a general guide to the removal and installation of an evaporator.

 

The Evaporator is the low pressure part of the auto air conditioning system that is usually inside the car behind the dashboard. It integrates with the heater and the fan to give you cooling inside your car.

 

WARNING: ANY WORK THAT REQUIRES DEGASSING OR REGASSING OF AN AUTO AIR CONDITIONING SYSTEM MUST BE CONDUCTED BY AN AUTHORISED OPERATOR.

DO NOT ATTEMPT TO DEGAS OR REGAS A CAR AIR CONDITIONING SYSTEM YOURSELF.

 

Do NOT commence the below process until all gas has been removed from your car's air conditioning system by an authorised operator.

 

Every car type requires a different process to remove the evaporator. If you are unsure what to do you will need either a comprehensive workshop manual or you will need to visit an experienced mechanic. Some cars can take 1 hour to remove and refit, others can take 8 hours.

1. Before you commence it is good practice to disconnect the battery terminals as the dashboard area has a lot of wiring behind it.

2. Most evaporators are located near or next to the heater therefore the complete heater/evaporator box needs to be removed. If this is the case both the evaporator connections and the heater pipes must be disconnected under the bonnet. Any heater box mount bolts under the bonnet must also be undone.

3. The next step is to follow the process inside the car's workshop manual to remove the evaporator. This section is specific to the actual car you have and varies from model to model.

4. Once the evaporator is out, check that the new one matches the old one and reinstall.

5. Finally, the car must be regassed. Regassing should only be undertaken by an authorised and licensed operator. They will know the correct procedure and the correct quantity of gas to use.
