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

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 sensor, I would recommend draining the coolant and disposing of it properly. and take your time to ensure the new sensor is screwed in properly and securely.
