Testing - Oil Cooler Bypass Valve
Caution: The flash point of new lubricating oil is ap-
proximately 221°C [430°F]. Do not allow oil temperature
in the container to exceed 149°C [300°F]. Do not allow
water droplets to enter the container of hot oil. Water
droplets will cause a violent reaction which can cause
personal injury.
Suspend the valve and a 116°C [250°F] thermometer in
a container of new lubricating oil. Do not allow the valve
or the thermometer to touch the sides or bottom of the
container.
Heat the lubricating oil.
NOTE: Record the temperature at which the valve is fully
extended. The valve must be fully extended to at least 6 mm
[0.250-inch] when the temperature reaches 116°C [240°F].
Replace the valve if it does not operate as described.
