Forklift Thermostat 65.06402-0006 – Daewoo DE12 Bus Truck

Forklift Thermostat 65.06402-0006 — Daewoo DE12 Engine Cooling Thermostat for Bus, Truck & Industrial Applications

This forklift thermostat part number 65.06402-0006 (cross-references 51.06402-0062) is a Kingstream OEM cooling thermostat for the Daewoo DE12 diesel engine used in buses, trucks, and compatible industrial forklift applications. The DE12 is a 12-liter diesel engine platform powering heavy-duty Daewoo buses and trucks, and this thermostat is an OEM-compatible replacement that regulates engine coolant temperature between the engine block and radiator. 0.2kg with 15×15×3cm carton box packaging. 1-year warranty with MOQ 1 piece. EXW, FOB, or CIF trade terms from Shanghai port. T/T or PayPal payment. Kingstream OEM quality.

Installing the 65.06402-0006 thermostat on a Daewoo DE12 engine requires draining the engine coolant below the thermostat housing level, removing the housing bolts, extracting the old thermostat and gasket, cleaning the housing mating surfaces of old gasket material, installing the new thermostat with the sensing element facing into the engine block, installing a new gasket, and torquing the housing bolts to specification. The thermostat orientation is critical — the spring side and thermal sensing bulb must face the engine block to sense the coolant temperature. After installation, refill coolant, bleed trapped air from the cooling system, run the engine until the thermostat opens, and verify no coolant leaks at the housing. For DE12 engines in fleet bus and truck operations, a stuck-closed thermostat causes rapid overheating and potential cylinder head damage on a 12-liter engine — preventive thermostat replacement at scheduled intervals is far less expensive than the engine damage from an undetected thermostat failure. 1-year warranty covers manufacturing defects and thermal element reliability.
