VDO SingleViu 52mm (2-1/16") Cylinder Temp. Gauge - 400°F - 471-14 Ohm

The VDO SingleViu 52mm (2-1/16") Cylinder Temperature Gauge is a precision engine monitoring instrument designed for serious gearheads and performance-focused mechanics who demand accurate real-time cylinder head temperature data. This OEM-quality gauge fills a critical gap in engine diagnostics, allowing you to monitor heat buildup across your cylinder head—essential when tuning high-output engines, diagnosing thermal stress, or verifying cooling system performance under load. Whether you're street tuning a modified daily driver or troubleshooting overheating issues on a racing engine, reliable cylinder temperature feedback prevents catastrophic engine damage and informs critical tuning decisions.

Built by VDO, a trusted OEM supplier and industry standard in automotive instrumentation, this gauge features a 52mm (2-1/16") dial face with a full-scale range of 400°F, optimized for detecting thermal anomalies in modern and classic engine configurations. The 471-14 ohm sensor specification ensures compatibility with VDO's proven thermal sensing network and integrates seamlessly into existing engine bay wiring harnesses without complex adapters. The single-needle mechanical movement provides fast, accurate readings with minimal lag—critical when monitoring transient heat spikes during hard acceleration or sustained high-RPM operation. Mechanical gauges like this eliminate electronic drift and offer reliability independent of vehicle electrical stability.

This gauge suits engine builders, tuners, and mechanics upgrading cooling diagnostics on performance builds, turbocharged platforms, or vehicles with marginal factory cooling capacity. Installation requires sensor placement in a cylinder head boss or water jacket location where direct temperature measurement occurs; consult your specific engine platform's thermal management schematic to identify the optimal sensor location. The compact 52mm diameter fits most aftermarket gauge clusters and custom dash panels without requiring substantial modification. Pair this with a quality coolant temperature gauge and oil pressure sensor for comprehensive engine thermal monitoring that keeps your build safe and responsive across all operating conditions.
