COOLANT PRESSURE METER
The coolant pressure meter shows the water pressure of cooling water passage, and provides a
warning for the operator when there is a problem with the cooling system.
* For all in-line cylinder models, the position for installing the sensor shares the coolant temperature output.
Therefore, either the coolant temperature meter or the coolant pressure meter can be used for one engine.
* However, on V4, V6, and F150 models, both meters can be used for one engine.
