Worked good while it lasted
Product is great, worked good for my 2012 Chevy Cruze. My car did blow up recently though with an issue due to the coolant all escaping but it wasn't from the reservoir. So would recommend. Also was easy to install and fit how it should've.

Perfect replacement tank and superior quality!
This Dorman replacement coolant tank was absolutely a perfect replacement for my 2013 Chevy Cruz. Perfect placement and the quality of the build is twice that of the original OEM tank. The amazing part is the replacement tank had what appears to be stainless steel tubing reinforcing the inlet/outlet tubes. The OEM tank didn't have that. Thank you Dorman for rescuing me from 3 months of total terror from cooling issues with my vehicle. Recommended 100%.
