Description
Product Overview
The Capshat Coolant Temperature Sensor is engineered specifically for Honda ATVs such as the TRX450R, TRX500FA, and TRX650FA series. Constructed from high‑grade stainless steel and a durable polymer housing, the sensor resists corrosion from coolant and extreme temperatures. It measures 1.5 x 1 x 0.45 inches and weighs only 1.6 ounces, making it a lightweight yet robust component. The sensor matches the original equipment part number CHTS-37750MAZ003 and is compatible with OEM part numbers 37750‑MAZ‑003, 37750MAZ003, and 37750 MAZ 003. Its precise thermistor element provides real‑time water temperature data to the ATV’s ECU, helping maintain optimal engine performance.
Usage
Designed for off‑road enthusiasts and daily riders, this sensor fits seamlessly into the cooling system of Honda ATVs built between 2001 and 2014. Whether you are tackling rugged trails, navigating farm work, or commuting on paved roads, the sensor monitors coolant temperature to prevent overheating during prolonged operation. Installation requires only basic hand tools; the sensor bolts directly into the existing coolant passage, eliminating the need for modifications. Ideal for riders who demand reliable engine cooling in demanding environments.
