(7) Mounting Bracket (8) Left Side Branch
There are three ways of checking if the water valve has been mounted correctly:
The mounting bracket (7) for the cable should be pointing toward the rear of the machine.
The water supply from the thermostat housing on the engine should be connected to the left side branch (8) of the water valve.
When you remove the two hoses the "ARROW" on the water valve should be pointing toward the rear of the machine. If the "ARROW" on the water valve is pointing toward the front of the machine, the water valve has been installed incorrectly.
Install a clamp onto both hoses on the water valve in order to prevent engine coolant loss. Alternately drain the coolant into a suitable container. Refer to Operation and Maintenance Manual, "Cooling System".
