Fixed the low coolant issue
Fit perfect. Easy to install. Most importantly it fixed the low coolant message that would pop up every time I started my truck.

Fast delivery, good quality, fits my 2017 Chevy 2500HD perfectly.
delivery was quick, installation took a while until I could afford a mechanic, SOOOOOOOOO nice not to have the constant "add coolant" messages while driving. I understand that this is common with my Duramax engine but I love my truck and that is the only thing that has ever gone wrong with it in 10 years.

Identical part you would buy from GM dealer.
This part is a GM factory part in a GM box. Identical to one you would buy from a GM dealer. All fits well and works.
