The Beck/Arnley 158-0629 Engine Coolant Temperature Sensor is an OE-spec replacement sensor designed to accurately relay coolant temperature to your vehicle’s ECU while resisting corrosion and harsh under-hood conditions.

This sensor is built to meet foreign original-equipment specifications for form, fit and function, giving you a direct-fit replacement that communicates coolant temperature precisely to the engine control unit. Beck/Arnley uses global sourcing and quality checks so the part installs cleanly and performs reliably in typical automotive environments. The 158-0629 is application-specific, with terminals and coatings made to resist corrosion and a housing engineered to withstand heat, vibration, and exposure to engine fluids.

How does this sensor help my car’s engine management?

The coolant temperature sensor provides the ECU with real-time coolant temperature data so the engine can adjust fuel delivery, ignition timing and fan operation. Accurate readings help your vehicle run as intended under different operating conditions.

• Feeds precise temperature data to the ECU for optimized fueling.
• Supports proper cooling fan activation thresholds.
• Helps maintain stable idle and emissions control during warm-up.

What makes the Beck/Arnley 158-0629 different from generic sensors?

This Beck/Arnley sensor is manufactured to match OE form, fit and function so it installs without modification and works with the vehicle’s original wiring and connectors. Materials and tolerances are specified to endure engine heat and vibrations while preserving signal accuracy.

• Engineered to OE dimensions for a direct replacement.
• Corrosion-resistant terminals and protective coatings included.
• Built to withstand high temperatures and engine bay contaminants.

How do I know if the 158-0629 fits my vehicle?

Beck/Arnley supplies application-specific parts; confirm fitment by checking your vehicle year, make and model against the part number or consult the seller’s fitment guide. Using the correct application avoids electrical mismatches and ensures proper sensor operation.

• Check the compatibility chart or VIN-based fitment tool before ordering.
• Verify connector style and thread size match the original sensor.
• Contact the parts specialist if you need confirmation of fitment.

What should I expect during installation and maintenance?

Installation is straightforward for technicians and experienced DIYers because the sensor is designed for a direct swap with existing wiring and mounting points. Minimal maintenance is required beyond ensuring engine cooling system integrity and clean electrical contacts.

• Typical install: remove the old sensor, clean port, install new sensor with proper torque.
• Use thread sealant only if specified by vehicle manufacturer.
• Inspect connector and wiring for corrosion or damage during replacement.
