Description

The Gates 34146 is a heavy-duty engine coolant thermostat designed for heavy-duty trucks, buses, tractors, and heavy equipment. It features a temperature-sensitive heat motor for consistent valve response and precise engine cooling.

Constructed from heavy-gauge brass and stainless steel for corrosion resistance, this thermostat includes jiggle pins for air venting, seals, and gaskets that are equivalent to original equipment parts. It is quality-controlled and factory-calibrated to ensure accuracy regardless of pressure changes.
