803&1&25 803&1&30 Water Temperature Sensor VDO Compatible Engine Coolant Sender
The POPULACE 803 series water temperature sensor is a variable-resistance engine coolant monitoring component covering seven VDO-compatible part numbers — 803/1/25, 803/1/30, 803/1/1, 803/1/2, 803/1/4, 803/2/7, and 805/3/1 — delivering a direct-fit analog resistance signal to compatible gauges and alarm panels without calibration software or additional processing hardware. Standard threaded installation enables field replacement in under fifteen minutes, making this water temperature sensor a practical choice for diesel generator service teams, marine engineers, and heavy equipment maintenance crews across power generation, marine, construction, agriculture, and mining applications. The sensor body is built to withstand sustained engine heat, vibration, and coolant chemical exposure, and each water temperature sensor ships with a six-month quality warranty covering confirmed manufacturing defects. Available at single-piece MOQ with 3–7 day dispatch via air express, sea freight, or courier, this water temperature sensor supports both emergency one-off repairs and volume distributor stocking orders from the Shiyan, Hubei production facility.
