Review on 🔧 Dorman 603-383 Engine Coolant Reservoir: Reliable Choice for Buick/Chevrolet Models by David Dreher

This was a great OEM replacement part that solved my coolant problem. You can tell this part is a much better designed piece by having steel reinforcement in the areas stressed by the spring clips. I would buy it again but I know I don't have to. Installation Tip: Go to YouTube and search. There is a detailed video on installing this part in a Chevy Cruze. It can also be a good time to flush the coolant in your system. This is important because if the system was not sealed (leaky), contaminants could enter the system. There is also a good video on how to do it step by step. Just find a channel: DIY with Michael Borders. You can flush your own coolant with genuine OEM (Long Life) coolant for about $30-$40.
