The Gates 33779 OE Type Thermostat is built for direct replacement cooling system service with OEM-equivalent fit and temperature control. It is a 195-degree thermostat designed for vehicles such as the Ford Explorer, Ford Ranger, and Mazda B4000, where stable coolant regulation is critical to engine performance.

Gates OE Type Thermostats are engineered for accurate opening temperature control and a leak-resistant seal at the housing interface. The reverse poppet design, steel and copper construction, and jiggle pin weep hole support consistent coolant flow and air bleeding during service.

Product Details

This Gates thermostat is built for applications that call for a 195-degree OE temperature setting, including Ford Explorer and Ford Ranger service, along with Mazda B4000 coverage. The Gates 33779 uses a reverse poppet layout to help regulate coolant flow at the specified opening point, while the steel and copper body supports durable operation in the cooling system.

The OE Type Thermostat line is focused on precise temperature control and a fit that matches the original housing requirements. This part cross-references Motorad 201-192JV for the same application.

What It Helps Address

• Air trapped in the cooling system after service

Installation Notes and Tips

Install the thermostat with the jiggle pin oriented to allow trapped air to escape during filling. Verify the housing surface is clean and inspect the sealing area before assembly. Confirm the 195-degree specification and OE-style fit before installation on Ford Explorer, Ford Ranger, Mazda B4000, or other listed applications for the Gates 33779.
