good.. perfect fit to my 2017 acadia
It worked great!!! Was much cheaper than the OEM.
Product arrived quickly and was well priced compared to local stores. The installation video was spot on!
Has been working good. No complaints.
No, this is all you need to replace the thermostat. The replacement takes time and patience, but can be done.
