High quality aluminum, not the average plastic ones!

Little modification, but after that was great

This is a good upgrade for your truck, but be aware you might have to do a little modification to it. Mine wouldn't fit into the hole so had to grind the metal sleeves down a little cause they don't flex like the OE plastic ones.

A+ would buy again if I needed another.

Cadillac Escalade thermostat/housing

Excellent fit, and their video installation library is always extremely helpful. The video library is the main reason I shop at 1A Auto.

Did not work

I wanted this to work. It looks heavier duty and nicer than OE. But it was too big and did not fit. I did not want to force it in or modify the part.

Yes...this fits...my 2014 Sierra has the exact same motor....only difference is it's chrome for whatever reason and factory one is not but mine fit and worked great! I've also installed one on a 2018 Silverado with a 5.3 belonging to a friend...good luck
