Keep your truck engine oil cool with the digital accuracy of a superior Oil Temp Gauge.

This top end, digital oil temp gauge is Made in the U.S.A. and comes with a Lifetime Warranty. The pinpoint accuracy sensor measures temperature from 100 to 300° F. If the oil temp drops below 100° F, the digital display will scroll “LO” to let you know the temperature is too low. The digital oil temperature sensor is fully adjustable and comes with a 12’ cable. The stylized chrome or black bezel gauge fits in a standard 2 1/16” spot on the dash. The auto temp gauge install is a cinch for your truck, motorhome, RV, tractor or car.

Oil temp sensors tell you what temperature your truck engine is running at so you can keep the engine running at the right temperature. This high accuracy of this oil temp gauge can replace the inaccurate stock gauge and give you the knowledge you need to protect your engine.

When installing a Teltek digital auto temp gauge, you may want to think about what which gauge fits your truck best. We advocate the Teltek oil temp gauges for their high-end precision, resilience and large digital display. You will need the oil temperature sensors, a line to the sensor and the temperature sensor (which are all included with Teltek oil temp gauges).

Why are engine oils and oil temp gauges necessary? Commercial truck engines generate mechanical power by extorting force from combustion. Most of the high temperature energy is exploited to generate mechanical power for the drive train. Engines are not proficient; much of the energy created by combustion flees the combustion chamber in the form heat. This wasted heat must be taken out of the engine through the exhaust or coolant systems. Thus, all engines need exhaust and cooling systems operate. The oil temperature can be employed to determine the temperature of the engine, and that is why truck drivers use a digital oil temp gauge.

The workings of an engine dissolve at a temperature that is less than the temperature generated in combustion engines in the combustion chamber. The temperature of the combustion chamber is also elevated to a level that will catch fire to the engine lubricants. Digital oil temp gauges keep you knowledgeable regarding your coolant system.

A Teltek oil temperature sensor informs the owner of the vehicle if their radiator is functioning to the optimal level. A radiator exchanges heat with cool air. Engine heat is transferred to the radiator were air cools the water so the water can be sent back to the engine. Most engines that are fluid cooled use another substance in addition to H2O to cool the engine. Water does well cooling the engine since it has a high specific heat capacity, meaning that water does well absorbing heat from the engine. For instance, H2O soaks up 2x the heat energy that oil can soak up. 

The Teltek aftermarket oil temp gauge comes with a Lifetime Warranty. For styling, high accuracy, quality sensor gauges, you have come to the right place.
