Holstein 2CTS0426 Engine Coolant Temperature Sensor

The Holstein 2CTS0426 Engine Coolant Temperature Sensor is a direct OE replacement component designed to monitor coolant temperature and transmit critical data to your vehicle's electronic control unit (ECU). This sensor uses electrical resistance to measure coolant temperature, allowing the ECU to make real-time adjustments to fuel injection, ignition timing, and transmission shifting for optimal engine performance.

Key Features:

• Precision-engineered to duplicate OE component function for smooth engine performance and maximum fuel economy
• Manufactured with premium materials for rugged, long-term durability and heat resistance necessary for high engine operating temperatures
• Direct fit design ensures easy installation and proper integration with vehicle systems
• O-ring or gasket included where applicable for proper fit and leak-proof seal
• Built to meet OEM specifications for form, fit, and function

Because coolant temperature plays a vital role in engine performance calculations, a failing sensor can quickly lead to poor fuel economy, irregular temperature readings, engine overheating, or check engine light activation. The Holstein 2CTS0426 restores your vehicle to factory levels of performance with reliable, accurate temperature monitoring. Backed by Holstein's 3-year/36,000-mile warranty.
