Removal Procedure
Start By:
- Remove the variable valve actuator. Refer to Disassembly and Assembly, "Valve Actuator (Variable) - Remove".
Note: Put identification marks on all hoses, on all hose assemblies, on all wires, and on all tube assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
