Detailed Description

This Dorman thermostat housing assembly is engineered for the cooling system service needs of Fiat 500, Fiat 500L, Fiat 500X, and Dodge Dart models listed in the fitment data. Dorman 902-3041 follows the original housing layout with a 0.7 inside diameter, 3.5 flange length, 1.85 flange width, and 0.4 flange thickness, helping maintain the correct coolant passage and mounting geometry. The assembly uses a gasket seal and includes the thermostat and sensor required for the application.

This part cross-references Gates 34816 and Motorad 757-176 for the same application.

What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or warped housing surfaces
• Improper engine warm-up from a worn thermostat
• Temperature sensor issues tied to the housing assembly
• Cooling system service on Fiat 500, Fiat 500L, Fiat 500X, and Dodge Dart models

Installation Notes and Tips

Confirm the vehicle year, make, and model before ordering. This assembly uses two mounting holes and does not include mounting hardware. Inspect the mating surfaces, replace the gasket seal during installation, and verify coolant level and system operation after service. Because the thermostat and sensor are part of the assembly, this part is suited to repairs where the housing and related components are serviced together.

Quality Assurance

Dorman designs this replacement thermostat housing assembly to match the fit and durability of the stock housing on the listed vehicles. The aluminum and steel construction is specified to withstand extreme temperature changes for extended service life.
