Review on 🌑️ ACDelco 213-77 Engine Coolant Temperature Sensor: Genuine GM Original Equipment for Optimal Performance by Cody Wuol

Revainrating 5 out of 5

Good OEM product. for parts

Used on the driver's side in the Sonoma 94, cfi W engine. This is used to send readings to the dash (NOT PCM). Has a two wire socket but uses only one wire. Works as described. This is a wet sensor, so expect to drop the coolant and change it.

Pros
  • GOLS certificate
Cons
  • A newer model could have been selected
