AutoMeter - Z Series 2-1/16" Oil Temperature Gauge (100-250 F) - 2638

This AutoMeter Z-Series oil temperature gauge is designed for high-performance and custom applications where accurate engine oil temperature monitoring is critical. The gauge has a compact 2-1/16″ (52 mm) mount size and covers a range of 100 °F to 250 °F.

The Z-Series features AutoMeter’s air-core meter movement for smooth, accurate needle response and a clean, fully readable dial. It comes (in many cases) with a 1/8″ NPT sending unit plus 3/8″ and 1/2″ NPT adapter fittings for flexible installation.

The lighting is traditional incandescent around the perimeter of the dial face for clear visibility in nighttime driving.

Compatibility & Installation Notes

• Requires a 2-1/16″ (52 mm) gauge mounting hole.

• Install the included sending unit into an oil-galley or oil-feed port (1/8″ NPT), or use the adapters if your application uses 3/8″ or 1/2″ NPT.

• Connect gauge wiring per AutoMeter’s instructions; ensure sensor match and perform calibration checks if required.

• Because this is a precision performance instrument, confirm fitment, wiring, sender compatibility and clearances before final installation.
