Product Details

The Dorman 9021999 Engine Coolant Thermostat Housing Assembly provides a durable OE FIX solution for original equipment thermostat housings that commonly fail due to weak plastic construction. This upgraded replacement housing is constructed from metal rather than plastic, eliminating the warping and cracking issues that plague factory housings over time.

Key Features:

  • Upgraded metal construction replaces failure-prone plastic OE housing
  • Prevents warping, cracking, and coolant leaks associated with factory housings
  • Direct-fit replacement for original equipment
  • Includes integrated thermostat housing assembly for simplified installation
  • Engineered to restore proper coolant flow and temperature regulation

This assembly offers a long-term repair solution that addresses the root cause of thermostat housing failure. The metal construction withstands engine heat cycling and maintains proper sealing, preventing the coolant leaks that lead to overheating and engine damage.
