COOLANT TEMP. METER
The coolant temperature meter uses a sensor on the engine unit to indicate the temperature of the
cooling water inside the powerhead.
The meter has a red zone to indicate overheating so problems can be corrected before severe dam-
age occurs.
* For all in-line cylinder models, the position for installing the sensor shares the coolant pressure output.
Therefore, either the coolant temperature meter or the coolant pressure meter can be used for one engine.
* However, on V4, V6, F150, and F200 (L4) models, both meters can be used for one engine.
