🌡️ ACDelco OEM 213-820 Engine Coolant Temperature Sensor by GM Review

perfect. Installed on my '98 Chevy Silverado with a 5.7 Vortec engine. Now my temperature is displayed correctly on the dashboard. Many Thanks

In my case the thermostat was open so the engine ran cool all the time (no faulty temp sensor). I paid $6 to NAPA for a new thermostat and it's fixed.

Exact match as expected with OEM parts. The original lasted 20 years so replace it with an OEM one. It's a temperature sensor in the driver's side head that breaks if you remove the head while it's still attached. Lesson learned. Installed in 1997 on a Chevy 1500, 5.7 engine.

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.

My old sensor read like there was a short between the transmitter unit and the sensor unit so I replaced it with this one and it worked straight away. Perfect fit for my 1998 Chevy Tahoe. The threads are even sealed. As with all threaded components, but especially here, BE VERY CAREFUL NOT TO CROSS THE THREADS when installing this component. The replacement can be done without draining the coolant, but if you are unsure about pulling out the old sensor and screwing in the new non-cross-threaded
