Evaporator Installation without Support Plates
If no supports or brackets for hanging or mounting the evaporator were added prior to installing the insulation package
or liner, thru bolts with backer plates must be used to verify the evaporator is properly secured.
Each evaporator mounting bolt requires a backer plate. Backer plates (installer supplied) should be made from
aluminum (or painted steel) with the correct diameter hole per your bolt size.
Figure 18.
Example of backer plate shown.
•
Apply a bead of silicone sealant around the hole on both sides of each backer plate and install mounting hardware.
•
Remove the evaporator cover and install the evaporator directly to the support plates and tighten hardware
securely.
•
Once the hardware has been tightened, apply more silicone sealant on the bolt heads until they are completely
covered. This will help prevent water from migrating down the bolts and into the cargo area.
