Speedhut 4-1/2″ Met Water Temp / Oil Pressure Dual Gauge (R45-DG5-REV)

The Speedhut 4-1/2″ Met Water Temp / Oil Pressure Dual Gauge (R45-DG5-REV) offers a convenient and space-saving solution for monitoring two critical aspects of your engine’s health: water temperature and oil pressure. This single, high-quality gauge provides accurate readings for both, allowing you to stay informed about your engine’s operating conditions and potentially prevent costly damage. With its clear 4 1/2 inch display and integrated warning light, you can easily keep track of vital metrics. The gauge is designed for straightforward installation and comes complete with all the necessary sensors and wiring harnesses.

KEY FEATURES AND BENEFITS:

• Dual Functionality: Combines both water temperature and oil pressure readings into a single, easy-to-read gauge, saving valuable dashboard space.
• Metric Measurement: Displays water temperature in Celsius (ranging from 50 to 125°C), providing precise thermal information.
• Imperial Measurement for Pressure: Shows oil pressure in PSI (ranging from 0 to 100 PSI), allowing for quick assessment of lubrication system performance.
• Large, Clear Display: The 4 1/2 inch gauge face ensures excellent visibility of both temperature and pressure readings, even at a glance.
• Integrated Warning Light: Features a built-in warning light that can be configured to alert you when either the water temperature or oil pressure exceeds a predefined safe level.
• Complete Installation Kit: Ships with the necessary Speedhut temperature sensor, a 100 PSI pressure sensor, and dedicated wiring harnesses for each sensor, simplifying the installation process.
• Power and Lighting Harness Included: Comes with a 3 ft power and lighting harness specifically designed for LED-lit gauges, ensuring proper illumination for nighttime visibility.
• Mounting Hardware Included: A gauge mounting ring is provided, making installation into a compatible 4.250-inch (108mm) cutout straightforward.

HOW TO USE:

1. Mount the Gauge: Locate a suitable 4.250-inch (108mm) diameter hole on your dashboard or instrument panel. Insert the Speedhut dual gauge into the hole and secure it using the included mounting ring from the back.
2. Install the Temperature Sensor: Identify the appropriate location on your engine (typically the thermostat housing or a designated port) to install the Speedhut temperature sensor. Ensure it is properly threaded and sealed.
3. Connect the Temperature Sensor Wiring: Connect the 2-wire temperature gauge wiring harness between the temperature sensor and the corresponding terminals on the back of the Speedhut gauge.
4. Install the Pressure Sensor: Locate the oil pressure sending unit port on your engine block. Remove the existing sensor (if present) and install the included 100 PSI pressure sensor, ensuring a secure and leak-free connection.
5. Connect the Pressure Sensor Wiring: Connect the 3-wire pressure gauge wiring harness between the pressure sensor and the corresponding terminals on the back of the Speedhut gauge.
6. Connect the Power and Lighting Harness: Connect the 3 ft power and lighting harness to a suitable 12V power source (ignition switched is recommended), a ground point, and the lighting circuit of your vehicle (if desired for dimming or specific lighting control). Refer to the wiring diagram provided with the gauge for correct connections.
7. Configure the Warning Light (if applicable): Some Speedhut gauges allow you to set the threshold for the warning light. Consult the gauge’s instructions on how to program the desired temperature and pressure limits for the warning indicator.
8. Test the Gauge: Once all connections are made, start your vehicle and observe the gauge readings to ensure they are functioning correctly. Check that the warning light activates if the temperature or pressure goes beyond expected levels.
