Detailed Description

This engine coolant thermostat housing is engineered as a direct replacement for specified Jeep and Oldsmobile cooling system applications. The metal construction is selected to handle repeated temperature swings, helping the housing maintain fit and sealing performance over time. Dorman 902-3014 is a practical choice when replacing a cracked, corroded, or leaking thermostat housing on Jeep Cherokee, CJ5, CJ7, J10, J20, and Wagoneer models, as well as the listed Oldsmobile Cutlass application.

The housing includes a gasket and uses a 45-degree neck angle with a 1.5-inch outlet port. The bleeder valve helps release trapped air during coolant service, which is important for stable cooling system operation after repairs.

What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or warped housing surfaces
• Corrosion-related sealing problems
• Air pockets after cooling system service
• Fitment issues from a worn original housing

Installation Notes and Tips

Verify engine and housing configuration before installation, especially on Jeep Cherokee, CJ5, CJ7, J10, J20, and Wagoneer models. Clean the mating surfaces thoroughly, inspect the thermostat and related hoses, and confirm the gasket seats evenly before tightening the housing. Because the thermostat is not included, reuse or replace it separately as needed.

Quality Assurance

Dorman designs this replacement housing to match the stock part’s fit and durability on the listed vehicles. The metal construction and temperature-resistant design support long service life in demanding cooling system conditions.
