Jaycar Water Temperature Sender – 6–24V, ±3°C Accuracy, ¼ NPT/BSP Thread, M5 Terminal

Gauge reading wrong? Or no sender at all and you're wiring a new dash? This is the sensor that makes the number honest. Rated 6 to 24V, holds ±3°C accuracy across the range. Resistance drops from 300Ω at 40°C down to 20Ω at 120°C — standard curve, so it plays nice with the MGG505 gauge. Thread is ¼ 18THD (NPT or BSP), M5 screw terminal for the wire. Give it three minutes after power-up to settle before you trust the first reading. Add to cart and stop guessing at coolant temp
