When replacing an AC evaporator due to cracking, always install the new AC Hose Clamp 94-81-961 in place of the original clamps. The new clamp
reduces the level of engine vibration that can be transmitted to the evaporator. Certain models (those equipped with the SeikoSeiki compressor) also
require the addition of a wire guard beneath the clamp to protect against wire chafing.

Before replacing an evaporator that is suspected of being cracked, always check the integrity of the expansion valve (copper tube evaporator only).
Replacement of an expansion valve is simpler and more economical than replacing the entire evaporator.
From the following VIN Serial Nos., the new clamp was also introduced into new car production:
