Description

The Gates 33599 is a heavy-duty engine coolant thermostat designed for heavy-duty truck, bus, tractor, and heavy equipment applications. It features a Weir-Stat design and is constructed from heavy-gauge brass, steel, and copper for corrosion resistance.

This thermostat opens at 190°F (88°C) and includes two seals, an O-ring and a perimeter seal, to ensure it is equivalent to original equipment parts. Its temperature-sensitive heat motor provides consistent valve response for precise engine cooling.
