Built to address common cooling system wear

This Dorman coolant water outlet is engineered to replace the original plastic housing on select Chrysler Town & Country, Dodge Grand Caravan, Volkswagen Routan, Chrysler Pacifica, Chrysler Voyager, and Dodge Caravan applications. The aluminum body is intended to better handle underhood temperature extremes, reduce the chance of leaks at the plastic weld area, and help lower future maintenance on the cooling system. Part number 902-313XD is also referenced for the same application as Motorad CH2313 and OE number 4666054AA.

Common problems this part can address

• Coolant leaks from cracked plastic outlet housings
• Heat-related brittleness in the original thermostat housing
• Repeated cooling system service caused by outlet failure
• Loss of coolant protection from a leaking water outlet
• Fitment issues when replacing a worn OE plastic housing

Installation notes and tips

Verify the inlet and outlet port dimensions, bolt-hole spacing, and hose connection style before installation. Clean the mating surfaces thoroughly and inspect the gasket sealing area for debris or old residue. Dorman 902-313XD uses a bolt-on design with an included gasket or seal, so proper alignment and even tightening are important for leak-free service.
