Durable and strong!
As a GM part it worked well and loved up to it's name! It was easy to install and I never had a problem with it! A little on the expensive side, but to be expected either GM parts. It did not die again while I had the vehicle.

OE Part Works Great!
Quick delivery! p0116 p0119 diagnosis showed my OE sensor off by 40 degrees. Ran two tests and confirmed wiring good, and Ecm also good. Ez to replace and almost no coolant loss. GM part works perfectly.

Perfect Fit
Perfect fit for the 2011 Buick Encore I bought it for. Easy install if you know what you’re doing. Cleared the engine code and have had no issues since.

Temperature sensor for 2013 Chevrolet Malibu
Deco sensor was installed but one issue was the sensor didn’t come with a retainer clip .A clip was acquired at the auto parts store to complete the installation .The clip removed from original sensor was made of inflexible metal and after dropping the clip at least five times ,it fell into who knows where .Recommend future customers be made aware and either include or make retainer clips available .

Genuine drop-in replacement. Works fine.
Not much else to say. It seems to be a genuine part, and it worked fine first try.
