Dorman 902-2090 is a direct-replacement engine coolant thermostat housing assembly built to match OEM fit and resist cracking under wide temperature swings.

This replacement thermostat housing assembly from Dorman is designed for GM trucks and SUVs from select model years and aims to restore proper coolant flow and sealing where the original water outlet has failed.

Will this housing fit my Cadillac Escalade or Chevrolet Silverado?

Compatibility covers a range of Cadillac, Chevrolet and GMC models across multiple years; however, fitment depends on trim and engine options. Use the site’s Confirmed Fit bar and enter your vehicle details to be certain. If you see an information icon, hover to read fitment notes specific to certain trims.

• Fits many Cadillac Escalade and Escalade ESV years 2015–2020
• Covers Chevrolet Silverado 1500/2500 models from 2014–2019 depending on model
• Works with several GMC Sierra and Yukon model years listed in the fitment

How does this housing stand up to extreme temperatures?

Dorman engineered the housing to resist cracking, warping and leaks that occur from repeated thermal cycles. The materials and construction are selected to tolerate hot coolant temperatures and the stresses of repeated heating and cooling without deforming. That helps preserve the seal against the engine block and thermostat interface.

• Thermally resistant construction minimizes heat-related failures
• Designed to maintain gasket sealing under pressure and temperature shifts
• Reduced risk of coolant loss and engine overheating due to leaks

What should I expect during installation and service life?

Installation is intended to mirror the original housing replacement process—mounting, gasket seal and hose connections align with factory locations. Expect a straightforward swap when replacing a failed water outlet, provided you confirm correct fitment first. Proper installation and torqueing help ensure long-term performance.

• Direct-replacement design matches factory mounting points
• Gasket and fastener locations correspond to original assembly
• Follow manufacturer torque specs and inspect hoses for wear during replacement
