Detailed Product Overview

This Gates thermostat, part number 34773, is engineered for vehicles that use an integrated thermostat housing rather than a separate thermostat-only layout. By matching the OE opening temperature and housing configuration, it supports proper coolant flow control in the engine cooling circuit. It is a direct replacement choice for drivers servicing Chrysler, Dodge, Ram, and Volkswagen applications that call for the 203-degree thermostat specification.

Compatible vehicle applications include 2011-2020 Dodge Grand Caravan, 2011-2019 Dodge Journey, 2011-2016 Chrysler Town & Country, 2012-2015 Ram C/V, 2011-2014 Chrysler 200, 2011-2014 Dodge Avenger, 2014 Ram ProMaster 1500, 2014 Ram ProMaster 2500, 2014 Ram ProMaster 3500, and 2011-2014 Volkswagen Routan. This part cross-references Stant 49559 for the same application.

What It Helps Address

• Engine running cooler or warmer than the OE temperature target
• Temperature fluctuation caused by a worn thermostat assembly
• Cooling system service on integrated housing applications
• Fitment issues when replacing a housing-style thermostat with the wrong configuration
• Loss of proper coolant flow control at operating temperature

Installation Notes and Tips

Verify the outlet diameter, bolt-hole count, and OE temperature specification before installation. This Gates 34773 thermostat is a non-electric unit with a 2-bolt integrated housing layout, so matching the original housing style is important for correct fitment. Confirm the vehicle’s cooling system configuration against the listed applications for Chrysler 200, Dodge Grand Caravan, Dodge Journey, and related models before service.

Quality Assurance

Gates develops aftermarket thermostat solutions for integrated housing applications and positions this part as an OE Exact replacement. The design is intended to match original equipment temperature control and housing requirements for the listed vehicles.
