Operation Guide
Before installation, confirm that the part numbers (3629205, 860149615) and specifications of the thermostat are compatible with the XE2000 excavator to avoid installation mismatch.
Shut down the excavator engine and wait for it to cool down completely. Drain the coolant from the cooling system to prevent scalding and coolant leakage during installation.
Remove the old thermostat by loosening the connecting bolts. Clean the installation flange and sealing surface thoroughly to remove dirt, rust, and residual coolant, ensuring a tight seal.
Install the new thermostat correctly, ensuring the temperature sensing element faces the engine side. Place the sealing gasket properly to prevent coolant leakage.
Tighten the connecting bolts evenly according to the specified torque. Do not over-tighten, as this may damage the flange or the thermostat itself.
Refill the cooling system with the specified type of coolant to the standard level. Start the engine, check for coolant leakage, and observe the temperature gauge to confirm the thermostat operates normally (temperature should stabilize within 80-95℃).
