Forklift Thermostat 2409001900300 – Quanchai 490 Wax Type Foton

Forklift Thermostat 2409001900300 — Quanchai 490 Wax Type Engine Thermostat for Foton Aumark & Forklift Engines

This forklift thermostat part number 2409001900300 is a Kingstream OEM Quanchai 490 wax type thermostat for Foton Aumark trucks and compatible forklift engines. The wax type thermostat is the industry standard design — a wax-filled copper thermal element expands when heated, pushing open the valve to allow coolant flow to the radiator. The Quanchai 490 is a widely deployed 4-cylinder diesel engine platform in Chinese trucks and forklifts. 0.1kg iron construction with OEM standard size. Original product quality with 6-12 month warranty. MOQ 2 pieces with neutral packing and 7-15 day delivery. Kingstream OEM quality.

Installing the 2409001900300 wax type thermostat on a Quanchai 490 engine requires draining the coolant below the thermostat housing level, removing the housing bolts, extracting the old thermostat and gasket, cleaning the housing mating surfaces thoroughly, installing the new thermostat with the wax-filled sensing element facing INTO the engine block, installing a new gasket, and torquing the housing bolts to specification. The orientation is critical — the wax bulb must sense the engine-side coolant temperature to function. After installation, refill coolant, bleed air, run the engine until the thermostat opens and the upper radiator hose becomes hot, and verify no leaks. For Quanchai 490 engines in Foton Aumark truck and forklift fleets, a failed thermostat stuck closed causes rapid temperature rise within 5-10 minutes of startup — the small 0.1kg thermostat controls the entire cooling system of a 4-cylinder diesel engine, and its failure can destroy a cylinder head gasket or warp the cylinder head if the overheat condition is not caught immediately. 6-12 month warranty covers wax element reliability and manufacturing defects.
