Beck/Arnley 158-1034 Engine Coolant Temperature Sensor

The Beck/Arnley 158-1034 Engine Coolant Temperature Sensor is a direct OE-replacement coolant temp sensor engineered to meet the original equipment specifications of foreign nameplate vehicles. The engine coolant temperature (ECT) sensor monitors the temperature of the engine coolant and transmits that data to the engine control unit (ECU), which uses it to regulate fuel delivery, ignition timing, and cold-start enrichment for smooth, efficient engine operation.

A faulty or worn coolant temperature sensor can cause hard cold starts, poor fuel economy, rough idle, incorrect temperature gauge readings, or illuminated check engine lights. Replacing it with a quality Beck/Arnley unit restores accurate ECU feedback and proper engine management.

Key Features:

• Matches OE form, fit, and function for precise drop-in installation
• Engineered to foreign nameplate OE specifications
• Sourced through Beck/Arnley's vetted global network of OE-quality suppliers
• Premium materials for reliable, long-lasting performance
• Restores accurate coolant temperature signal to the engine control unit
