Review on 🌑️ ACDelco OEM 213-820 Engine Coolant Temperature Sensor by GM by Badpuppy Warton

Revainrating 5 out of 5

Let the engine cool and pull the old one out

Revain was the only place I could find this sensor, it's the one on the dash that goes down next to the driver's side exhaust manifold. Not to be confused with the thermostat housing that goes to the ECU. Delivered quickly and installation was easy. The threads were provided with pipe sealant. Allow the motor to cool and remove the old one. Put a new one in, you will lose some antifreeze so be sure to check the level and top up.

Pros
  • A few competitors
Cons
  • Clarity
