Why Use a Water Temperature Gauge?
A water temperature gauge monitors engine coolant temperature to indicate dangerous overheat conditions.

The needle will indicate the current coolant temperature on the application being monitored. This reading should remain fairly steady. You will need to know what to expect from your system.

If the coolant temperature rises above the desired limit, you should reduce the load placed on the engine to help reduce the temperature and then determine what is causing the overheating situation and fix it.

Electric Full Sweep Water Temperature Gauge
Marshall electric water temperature gauges are connected, via wires to a temperature sender which is installed in a port in the system being monitored, providing the temperature information to the gauge.

CAUTION: Electric gauges that require senders must be "matched" with the correct sender. If a sender that does not have the same electrical match is used the gauge will not provide the proper readings and the needle may act erratically. Marshall Instruments electric water temperature gauges include the required sender.

Mechanical Water Temperature Gauges
Mechanical water temperature gauges are connected directly to a port in the system being monitored via a capillary tube and bulb. This capillary tube MUST NOT be cut, pinched or altered in any way or the gauge will not function.
