Engine Coolant Thermostat Housing Assembly

Dorman 902-5156 is a replacement engine coolant thermostat housing assembly for select Volkswagen 2.5L applications. It is built to match the original housing’s fit and durability, with a plastic black housing, integrated thermostat, and included gasket/seal for a direct replacement on covered vehicles.

Key Features

  • Plastic housing with black finish
  • Includes thermostat set to open at 176 degrees F
  • Gasket or seal included with standard gasket type

Detailed Description

This Dorman thermostat housing assembly is engineered for Volkswagen Beetle, Jetta, Passat, Golf, Golf SportWagen, Beetle Cabrio, and Bora models equipped with the 2.5L engine in the listed model years. The housing is made from plastic and uses a standard gasket design to help restore proper coolant routing and thermostat control. With a 1.06 inside diameter, 3 outlet ports, and a thermostat opening temperature of 176 degrees F, this assembly is built for OE-style replacement service. The Dorman 902-5156 is a practical choice when replacing a cracked housing, leaking seal, or thermostat-related cooling issue on a Volkswagen Beetle or Volkswagen Jetta 2.5L application.

This part cross-references Beck/Arnley 143-0908 and Motorad CH3002 for the same application.

What It Helps Fix

  • Coolant leaks from a cracked or warped thermostat housing
  • Engine temperature fluctuations caused by a worn thermostat
  • Coolant loss at the housing seal or O-ring area
  • Overheating or slow warm-up related to thermostat control
  • Cooling system service needs on Volkswagen 2.5L engines

Installation Notes and Tips

Verify engine size and vehicle application before installation. This housing uses two mounting holes and includes a gasket/seal and thermostat, but mounting hardware is not included in the product data. Clean the mating surfaces thoroughly before assembly and inspect adjacent coolant hoses and connectors for wear. Confirm the thermostat orientation and coolant routing match the original setup on the vehicle.

Quality Assurance

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