GASKET - THERMOSTAT (Doosan DWD700385)

A worn thermostat gasket can allow coolant to seep past the seal, leading to gradual fluid loss and potential overheating. This aftermarket replacement part references the Doosan catalog and carries the cross-reference number DWD700385. The gasket creates a leak-resistant barrier between the thermostat housing and its mating surface. Its primary mechanical function is to compress under fastener torque to fill microscopic irregularities. Over time, heat cycling can cause the gasket material to harden and lose its sealing ability. A failed gasket may result in visible coolant drips or a drop in the cooling system's pressure retention. Verify the serial number or application, then call (562) 693-7748.
