VDO Temperature Sender 250°F/120°C - 3/8-18 NPTF

The VDO Temperature Sender 250°F/120°C - 3/8-18 NPT is a precision engine coolant temperature sensor designed for accurate real-time monitoring of your engine's thermal state. Built by VDO, a trusted OEM supplier for decades, this sender connects your engine block to your gauge cluster or engine control module, providing essential data to prevent overheating and maintain optimal engine performance.

This temperature sender utilizes a variable resistance design that shifts impedance proportionally to coolant temperature across a 250°F (120°C) operating range, ensuring the signal linearity that modern engine management systems require. The sender features a brass fitting that threads directly into factory or custom coolant passages, ensuring a leak-free mechanical seal without the need for additional adapters or fittings.

Mechanics, engine builders, and enthusiasts upgrading to aftermarket gauges or standalone ECU tuning will find this sender essential for closed-loop cooling system diagnostics. Its compact form factor fits tight engine compartments typical of modified and stock installations alike, making it a versatile choice for various applications.
