4) Check thermostatic movement of wax pellet as follows :
a) Immerse thermostat (1) in water, and heat water gradually.
b) Check that valve starts to open at specific temperature.
If valve starts to open at a temperature substantially below
or above specific temperature, thermostat unit should be
replaced with a new one. Such a unit, if reused, will bring
about overcooling or overheating tendency.
INSTALLATION
1) When positioning thermostat (1) and O-ring on thermostat
case, be sure to position it so that
• Air bleed valve (2) comes at top (G16 engine).
• Air bleed valve (2) comes at match mark (3) and into the
recession of thermostat case (J20 and H25 engines).
2) Install thermostat cap to intake manifold (G16 engine), water
pump (J20 engine) or thermostat case (H25 engine).
3) Install cooling fan and fan shroud and connect radiator inlet
hose to radiator (H25 engine only).
4) Fill cooling system. Refer to “Coolant” and “Cooling System
Flush and Defill” in this section.
5) Connect negative (–) cable at battery.
