Exactly what our Sonic needed. Old tank had cracks in bottom. Good thing to check if your car is leaking coolant and you can't figure out why.

No problem installing it . It was the right one. I was surprised that the price was so low. It saved us from having to wait for months to collect the money to purchase it since it cost about $200 locally

I replace this water reservoir in my 2013 Chevy Sonic, looks very good and I spend about 30 minutes working and making sure the car was full of water.

Looked good initially when taken from the packaging. The reservoir did not last 5 months before it sprang a pinhole leak below the mold line. Looked like a spider web across the engine bay. Left me down at a very inconvenient time.

My original had a few cracks that were leaking so I ordered this and replaced it.
