Don’t be surprised if you see a pile leaves at the bottom
of the evaporator housing. Over time it’s common for
debris to sneak past the air inlet screen. Wiggle the housing for-
ward, up and out.

The replacement of the evaporator is easy once the hous-
ing is removed. Only three screws attach it to the housing.10
With the evaporator housing removed, you can see the
heater core and the door that can close to block air from
going through the heater core. Tip: take a minute to move the
heater control to make sure the door fully opens and closes.12
I strongly recommend that you test-fit the VIR or other
A/C parts that connect to the evaporator before install-
ing them in the car. If any minor bending is needed to an
evaporator tube, it’s far easier to do that now to make all the
tubes fit properly.13
The two forward mounting tabs need to be
bent up to a right angle. This is easily accom-
plished with needle nose pliers.

Clean the old sealant from the sealing groove using a
scraper or screwdriver. You don’t have to remove every
speck of old sealant; the new sealant is very effective.
