Beck/Arnley Coolant Temperature Sensor 158-0134 — OE-fit replacement, precision-calibrated for reliable ECU readings

Beck/Arnley Coolant Temperature Sensor 158-0134 is a direct-fit replacement sensor that provides the engine control unit with accurate temperature readings for proper engine management.

This sensor is engineered to match foreign original equipment specifications for form, fit, and function so you can replace the factory unit with confidence. Beck/Arnley leverages global sourcing and strict quality checks to deliver a component built to withstand high temperatures, coolant exposure, and road-side contaminants while maintaining a consistent electrical signal to the ECU.

How does this sensor ensure accurate engine temperature readings?

The 158-0134 is manufactured to precise tolerances and calibrated to produce predictable resistance changes as coolant temperature varies. That stable response helps the vehicle's ECU interpret engine conditions reliably for fuel delivery and ignition timing adjustments.

• Engineered to match OE calibration curves
• Precision sensing element minimizes signal drift
• Corrosion-resistant terminals preserve conductivity

What makes this Beck/Arnley sensor durable in harsh engine environments?

Materials and coatings are selected to resist coolant chemistry, heat cycling, and vibration common under the hood. The connector, terminals, and body are constructed to prevent corrosion and mechanical failure over time.

• High-temperature rated housing resists heat degradation
• Protective coatings on terminals reduce oxidation
• Robust mechanical design withstands vibration and pressure changes

Will this part fit my vehicle and work with the ECU?

Beck/Arnley parts are application-specific and built to meet the original equipment form and mounting points so installation is straightforward. The sensor’s electrical characteristics are matched to OE specifications to ensure the ECU receives the correct resistance-to-temperature signal.

• Designed to meet foreign nameplate OE fitment
• Application-specific part number for correct fit
• Plug-and-play electrical connector compatible with OEM harnesses

How easy is installation and what should I check during replacement?

Installation is typically simple: disconnect the battery, drain coolant if needed, unplug the old sensor, and swap in the new unit using the correct torque. Inspect the wiring harness and sealing surfaces for damage before final assembly.

• Basic hand tools required, minimal vehicle disassembly
• Replace sealing washer if applicable to prevent leaks
• Verify electrical connection and check for leaks after refill
