11K6-90540 Cab Heater Core for Hyundai HW140, HW160, HW180 Excavators

   The 11K6-90540 heater core is built with a high-density braze-aluminum construction to ensure maximum thermal conductivity and pressure resistance. Designed to fit the specific housing of the Hyundai HW-series wheeled excavators, it features reinforced inlet and outlet pipes to prevent leaks caused by the constant vibration and hydraulic fluctuations typical of heavy construction equipment.

Q1: What are the signs that my 11K6-90540 heater core is failing?

A: Common symptoms include a sweet "syrup-like" smell (antifreeze) inside the cab, foggy windows that won't clear, or wet floor mats. If your engine is warm but the cab vents are only blowing cold air, the core may be clogged internally.

Q2: Do I need to remove the entire dashboard to replace this core?

A: In the Hyundai HW-series, access typically requires removing the side console or the heater unit assembly located behind or beneath the operator's seat area. It is a labor-intensive process, so replacing seals and checking hoses at the same time is recommended.

Q3: Can I use stop-leak additives to fix a leaking heater core?

A: It is not recommended. While stop-leak might temporarily plug a pinhole, it can also clog the narrow passages of the heater core and the engine’s radiator, leading to cooling system inefficiencies or engine overheating.
