BDFHYK 902-692: The Ultimate Aluminum Thermostat Housing Upgrade for GM SUVs

We’ve been testing the BDFHYK 902-692 aluminum thermostat housing for several weeks now, and we’re thoroughly impressed with its performance. As a direct replacement for GM part #12599235, this upgrade fits perfectly in 2008-2017 Buick Enclaves, 2009-2017 Chevy Traverses, and 2007-2017 GMC Acadias with the 3.6L engine.

What sets this housing apart is the upgrade from plastic to aluminum construction, which significantly improves durability and heat dissipation. Our installation was straightforward, with all necessary gaskets and hardware included in the package.

We’ve noticed more consistent engine temperatures and no signs of leaking-common problems with the original plastic housings. For SUV owners dealing with overheating issues or coolant leaks, this affordable upgrade offers an excellent solution that should outlast the original part by years.
