The most effective location for a water temperature gauge on a vehicle is on the head or the side of the block. Generally, water temperature gauges are more accurate and fit better in these locations.
Your oil temperature gauge will connect to the oil pressure sensor. The water temperature gauge will hook up to the water temperature sensor. The oil pressure sensor will be on the left-hand side of the engine and the water temperature sensor will be on the front of the engine.
It goes to the temp gauge which is usually screwed in the head between the manifold on the drivers side, or into the thermost housing on the intake manifold.
only 3 reasons a temp gauge wont work the temp sender is bad the gauge is bad or the wire from temp sender to gauge is broken
check the temp sending unite on the water intake
why doesn't my rpm gauge and temp gauge, fuel gauge not work
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
operates the temperature gauge Activates the cooling fan
Need to know the year and engine size.
The temperature gauge should be connected to the transmission temperature sensor. The transmission temperature sensor is located on the right-hand side of the transmission.
Because the temp gauge is not giving you the temperature of the water/steam in the radiator. You may have a bad head gasket or a cracked head causing the coolant to have that boiling effect.
The temp gauge sensor screws into the driver side head atoms #2 and #3 plugs. The volt gauge hooks up to any ignition on hot wire and the other wire to chasis ground. Oil pressure gauge is just behind the distributor.
i have seen them on the intake, head, and thermostat housing also on the block in front
