Expansion Valve Insulation, Removing And Installing

-

Locate insulation over expansion valve as illustrated and press together two halves -A- and -B- until they clip into each other.

NOTE:
-

Depending on engine version, improved access may be obtained by removing front suspension cross brace.

-

Always ensure the expansion valve insulation is properly in place, and is not damaged.

-

Due to the thermo-dynamic design of the expansion valve, the operating parameters of the valve are adversely affected when the insulation is
missing or improperly installed. A decrease in cooling efficiency will result.
