Dorman 902-5045 Engine Coolant Thermostat Housing Iron Stock Replacement

The Dorman 902-5045 is a direct-fit replacement engine coolant thermostat housing engineered to restore proper cooling system function. Re-engineered to address common failure points found in the original equipment, this housing is constructed from cast iron for long-lasting durability against the extreme thermal cycling that causes OE plastic or deteriorated housings to crack, warp, and leak coolant.

Key Features:

• Cast iron construction — resists heat-related brittleness, cracking, and coolant leaks
• Stock water neck style — direct bolt-on fitment with no modifications required
• Gasket-sealed design — uses a standard gasket (not included) for a reliable, leak-free seal
• Heater bypass provision — maintains proper heater core coolant flow
• Thermostat not included — reuse your existing thermostat or replace separately
• Mounting hardware not included — reuse OE fasteners or replace as needed
• Sold individually

Dorman's OE Solutions line is professionally engineered to match or exceed original equipment specifications for fit, form, and function — delivering dealer-quality results at a fraction of the dealer price. This housing helps maintain the steady flow of coolant through the engine, reducing the risk of overheating and protecting against costly engine damage.
