Multiquip 0601803660 Thermostat BDW-180 - OEM Replacement Part

This thermostat regulates operating temperature in Multiquip diesel welders, protecting the engine from overheating damage while ensuring optimal performance during continuous welding operations. The BDW-180 thermostat opens and closes to control coolant flow through the engine block, maintaining the precise temperature range needed for efficient combustion and reliable arc output under heavy loads.

Critical for engine longevity and consistent welder performance, a failing thermostat can cause overheating, poor fuel efficiency, or prevent the engine from reaching proper operating temperature. Symptoms of thermostat failure include temperature gauge fluctuations, engine overheating during extended welding jobs, or unusually long warm-up periods. Regular inspection during scheduled maintenance helps prevent costly downtime on job sites.

This thermostat is compatible with the following Multiquip welder models:

• DLW-400ESA4
