Give the ECU an accurate read on engine coolant temperature with the Beck/Arnley Engine Coolant Temperature Sensor / Fuel Injection Cold Start Valve 158-0536. It drops in as a direct replacement that matches OE form, fit and function on a wide range of GM applications, including the 1996-1999 Acura SLX, 1985-1995 Buick Century, 2001-2005 Buick LeSabre, and 1985-2005 Chevrolet Astro — see the Buyer’s Guide tab for the full list of 577 applications.
This sensor reads engine coolant temperature and sends that signal to the ECU, which the module uses to trim fuel delivery and ignition timing across warm-up and normal operation. If a failed coolant temperature sensor is the cause of hard cold starts, a rough or high idle when cold, an inaccurate temperature reading, or a related check-engine light, this replaces it — diagnose the cause before replacing.
- OE match: matches OE form, fit and function.
- Precise signal: made to exacting tolerances for precise messaging to the ECU.
- Corrosion protection: includes corrosion-resistant terminals and coatings.
- Built for heat: constructed to withstand an engine environment.
