Detailed Description

Dorman 902-751 is a replacement water outlet/thermostat housing designed for Nissan Sentra, Nissan NV200, Nissan Rogue, and Nissan Versa applications listed in the fitment data. It is shaped to match the original housing geometry and mounting layout, helping maintain proper coolant routing at the thermostat location. The housing is built to handle extreme temperature changes, which is important in cooling system service where heat cycling can stress plastic components over time. This part cross-references Gates CO34796 and Motorad CH8751 for the same application.

What It Helps Address

• Cracked or warped thermostat housing
• Coolant leaks at the housing outlet or mounting surface
• Improper coolant flow caused by a damaged housing
• Cooling system service on Nissan Sentra, NV200, Rogue, or Versa models
• Replacement of a worn water outlet on the thermostat housing assembly

Installation Notes and Tips

Verify the outlet port diameter, mounting hole spacing, and 45-degree neck angle before installation. Because no gasket, seal, thermostat, or bolts are included, reuse or replace related service parts as needed during cooling system repair. Clean the mating surfaces thoroughly and inspect adjacent hoses and clamps for wear before refilling the system.

Quality Assurance

Dorman designs this replacement housing to match the fit and durability of the original part on specified vehicles. It is built for cooling system service where consistent sealing and temperature resistance matter.
