Detailed Product Description

Gates Premium Thermostat 34059S is engineered for drivers servicing cooling systems on vehicles such as the Dodge Charger, Dodge Challenger, Ram 1500, and Jeep Grand Cherokee. The stainless steel and copper build supports corrosion resistance, while the spring design helps the thermostat respond consistently as coolant temperature changes. With a 190-degree opening point, this thermostat is suited to applications that call for alternate temperature control in the cooling circuit.

This part cross-references Motorad 416-192 for the same application.

What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Temperature fluctuation from a weak or inconsistent spring
• Cooling system corrosion affecting thermostat operation
• Air trapped in the cooling system after service
• Delayed coolant flow control in 190-degree applications

Installation Notes and Tips

Verify the thermostat orientation, bottom by-pass design, and seal type before installation. Clean the housing mating surfaces thoroughly and inspect the cooling system for contamination or old gasket material. This part uses an O-ring seal and does not include an installation tool. Confirm vehicle-specific fitment for the exact year and model before ordering.
