I was surprised how easy it was to find the exact fit for my 03 duramax 2500 radiator overflow tank. Shipping was fast. I watched their video on changing mine out and it was easy to follow. Part looks and works great. Yes, I will go through A1 the next time I need a part.

Our parts are exact replacements for your vehicle's OEM parts. As long as your year, make, and model match up with our listing, these parts will directly fit and function like the originals and would include the sensor.
