Notes: GM Original Equipment -- With COOLANT SENSOR
This coolant bottle fit right in where the old one came out. It seems to be manufactured with high quality thick plastic. Parts geek shipped it to my home in a timely manor (though not free shipping which other auto parts sites offer). Overall I am very pleased with the experience I had with parts geek and this coolant bottle. Now it's only been on my ride for a couple of days so time will tell if it leaks or has any problems. So far so good!
