800168991 thermostat housing gasket XCMG XE2000 excavator spare parts

XCMG XE2000 excavator thermostat housing gasket (part number 800168991): high-temperature sealing, protecting the cooling system’s temperature control stability.

The thermostat of the XCMG XE2000 excavator is a core component controlling engine coolant circulation and maintaining engine temperature. The thermostat housing gasket, as the seal connecting the housing to the cylinder block, directly determines whether the cooling system leaks. If the gasket seal fails, high-temperature coolant will leak, causing abnormally high engine temperature, power loss, and even cylinder block corrosion and thermostat sticking. This article focuses on the XCMG XE2000 original factory thermostat housing gasket (part number 800168991). This high-temperature resistant sealing gasket for excavators, with its precise fit and strong resistance to thermal erosion, builds a solid “high-temperature sealing defense” for the cooling system.

Precisely compatible with XE2000: Seamless fit to original factory specifications

This thermostat housing gasket (part number 800168991) is custom-made to strictly conform to the sealing surface dimensions, bolt hole spacing, and groove depth of the XCMG XE2000 excavator thermostat housing. The inner diameter, outer diameter, and thickness errors are all controlled within ±0.02mm, ensuring a perfect fit with the original housing and cylinder block sealing groove. No cutting or grinding is required during installation; it can be directly applied to the sealing surface. After tightening the bolts, it forms a gapless seal with the housing and cylinder block, preventing “coolant leakage” or “deformation and breakage” caused by dimensional deviations. Ensuring that the thermostat housing connection meets the original factory assembly standards is the core advantage of the XE2000 dedicated thermostat sealing gasket.

High-temperature resistant material: heat-resistant and aging-resistant

Made of fluororubber (FKM) or reinforced asbestos rubber composite material (as per original design), it possesses superior high-temperature sealing performance: it does not soften or carbonize in the high-temperature environment of engine coolant (90-110℃), and shows no swelling or cracking even after long-term contact with antifreeze, with a sealing performance degradation rate of less than 3%; the material has strong resistance to thermal fatigue, maintaining stable elasticity even after frequent “cold start-high temperature cycle” conditions, avoiding seal failure caused by thermal expansion and contraction. Compared to ordinary rubber gaskets, its upper temperature resistance is increased by more than 40℃, and its service life is extended by 2.5 times, enabling it to adapt to the high-temperature working environment around the thermostat for extended periods.

Precision sealing design: Double protection against leakage and pressure

To address the sealing requirements of the thermostat housing, the gasket adopts a “flange sealing ring + flat sealing surface” structure: the flange ring is precisely embedded in the housing sealing groove to prevent gasket displacement; the flat sealing surface is finely polished, achieving a fit of over 98% with the cylinder block sealing surface. Under bolt tightening pressure, it can fill minor imperfections, forming a reliable sealing layer. Even under coolant pressure fluctuations (up to 1.2MPa) or engine vibration conditions, it can still tightly prevent high-temperature coolant leakage, avoiding a drop in cooling system pressure due to leakage. It is a typical leak-proof thermostat gasket for excavators.

As a sealing component for the cooling system of construction machinery, the XCMG XE2000 excavator thermostat housing gasket (part number 800168991) is an essential accessory for maintaining the original factory sealing standard and ensuring the efficient operation of the excavator. Choosing the original factory gasket means choosing a leak-free and safe cooling system and stable engine temperature control.
