Product Overview

This CAT 377-3016 (3773016) coolant temperature regulator is a precision cooling component designed for the CAT C9.3 diesel engine widely used in excavator applications. As an essential item within the CAT Genuine Parts lineup of Excavator Engine Parts, it automatically modulates the flow of engine coolant to keep the power unit operating within its ideal temperature window, supporting faster warm-up, stable combustion and consistent output under heavy-duty working cycles.

Coolant temperature regulators such as the 377-3016 / 3773016 play a key role in the engine cooling circuit of CAT C9.3 powered excavators: when the engine is cold the regulator keeps coolant circulating inside the block, and once normal operating temperature is reached it opens to allow full radiator flow. This CAT coolant temperature regulator is manufactured to CAT Genuine Parts dimensional standards, delivering dependable sealing and smooth opening response for CAT excavator engine parts maintenance and overhaul programs.
