Customer Q&A
I own a 2005 GMC Envoy with the 4.2. What is the difference between the 2 aluminum housing thermostats? My climate control is electronically controlled.

Yes, this part will fit your vehicle. There should not be a difference between the parts we are selling if they are listed as being able to fit besides the brands.
