The VDO 250f Temp Sender 1/4-18 NPT is a precision engine temperature sensing component designed for automotive cooling system monitoring and engine management applications. This sender converts coolant temperature into an electrical signal that feeds directly into your vehicle's gauge cluster or engine control unit, making it essential for real-time thermal diagnostics and performance tuning.
The sender operates via a variable resistance element that changes electrical resistance as coolant temperature reaches 250 degrees Fahrenheit. The 1/4-18 NPT threaded connection ensures a secure, leak-free mount into any compatible coolant passage or sender boss on your engine block or intake manifold. The compact form factor (3.2 x 0.95 x 5.55 inches, weighing just 0.09 lbs) minimizes installation complexity while maintaining the robust construction VDO is known for.
This temperature sender suits engine builders, performance tuners, and mechanics undertaking cooling system upgrades, engine swaps, or gauge cluster retrofits where OEM senders are unavailable or incompatible. Installation requires a proper NPT-threaded port and basic wiring to your gauge cluster.
