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.
