VDO SingleViu 52mm (2-1/16") Water Temp. Gauge - 250° F - 291-22 OHM

The VDO SingleViu 52mm (2-1/16") Water Temperature Gauge - 250° F is the OEM-grade instrument panel solution for serious engine builders, vintage restoration specialists, and performance enthusiasts who demand accurate coolant monitoring. This professional-grade gauge exists because engine temperature is one of the most critical parameters in vehicle health—overheating causes catastrophic damage, while running too cool reduces efficiency and increases wear. Whether you're tuning a modified street engine, restoring a classic vehicle, or diagnosing cooling system issues on your daily driver, this VDO gauge delivers the precision feedback you need to protect your investment.

The VDO SingleViu operates on a 291–22 OHM sender interface, a standard resistance-based temperature sensing protocol that integrates seamlessly with factory wiring harnesses and aftermarket engine management systems. The 52mm (2-1/16") round faceplate fits industry-standard gauge pod mounting locations, making installation straightforward in custom dash clusters or OEM-style gauge panels. VDO's reputation for accuracy and durability comes from precision mechanical movements and calibrated fuel-tank designs that eliminate needle flutter and ensure stable readouts even under heavy vibration—critical for high-RPM environments and aggressive driving. The 0–250° F scale covers the full operating range of most street and performance engines, giving you clear visibility of normal operating temperatures (typically 160–195° F) and early warning of thermal stress.

Mechanics and engine builders favor this gauge for retrofit installations into classic muscle cars, restomod projects, and custom EFI conversions where factory analog instrumentation is either missing or unreliable. It pairs flawlessly with modern engine bay sensors and vintage-style wiring, making it equally at home in a 1969 Chevelle or a 2005 LS-swapped hot rod. The compact 0.45 lb weight and 4 x 4 x 6 inch footprint simplify packaging in tight engine compartments, while the professional appearance matches both modern carbon-fiber gauge clusters and traditional round-dial instrument panels. Installation requires only a coolant passage sender tap, 12V switched power, and a ground—no complex electronics required, just reliable analog temperature monitoring.
