Immediate action: If the temperature gauge enters the red zone or you see steam from under the hood, pull over safely and turn off the engine. Do not attempt to drive further.

Step 5: Actuation Test (Bidirectional Scanner Required)

Command the valve to open and close using a scan tool. You should hear a faint clicking or whirring. No sound = mechanical failure.

Step 6: Monitor Coolant Temp Sensor Data

Compare actual coolant temperature with the valve’s commanded position. If the engine is at 200°F and the valve shows 0% open, replace it.
