Fitment Details

Fits 2001-2002 Nissan Sentra, N/A. This Dorman 902-5066 thermostat housing is listed for the engine coolant thermostat housing position in the cooling system. This part cross-references Valeo (e.g., 815571) for the same application.

Product Overview

Built as a stock-style replacement, this thermostat housing helps restore the coolant passage connection at the engine thermostat area. The plastic construction, included gasket, and OE-style mounting layout support a clean replacement on 2001-2002 Nissan Sentra cooling system repairs. Dorman 902-5066 is a practical choice when the original housing is cracked, warped, or leaking at the seal surface.

What It Helps Fix

  • Coolant leaks at the thermostat housing
  • Cracked or heat-damaged plastic housing
  • Warped sealing surface causing seepage
  • Cooling system service issues after thermostat-area repairs
  • Fitment problems from a worn original housing on a Nissan Sentra

Installation Notes

Verify the outlet port diameter, mounting hole layout, and 180-degree neck angle before installation. Transfer no bolts from the package, since bolts are not included, and confirm the thermostat is reused or replaced separately because it is not included. Clean the mating surfaces thoroughly and install the supplied gasket to help achieve a proper seal.

Quality Assurance

Dorman designs this replacement housing to match stock fit and durability and to withstand extreme temperature changes for extended service life.
