Product Description
The 0K62Z-10150C thermostat housing cover is cast from ADC12 aluminum alloy, with integrated one-piece hose nipples to address common coolant leak issues in aging commercial diesel engines. It is manufactured to Kia OEM standards and compliant with ISO/TS16949 automotive quality certification. All sealing surfaces are CNC machined to ≤0.05mm flatness, and an anodized surface treatment provides 3x better corrosion resistance against ethylene glycol coolants. This product suits replacement and aftermarket procurement for Kia commercial vehicle maintenance.

This housing shares identical dimensions with the original part in mounting hole positions, hose nipple angles and sealing surface measurements. No modification or additional parts are required for installation, ensuring consistent fit with engine blocks and cooling system hoses.
Made from ADC12 aluminum alloy with thermal conductivity, the housing withstands temperature fluctuations and coolant pressure without cracking or warping. All mating surfaces are CNC machined to micron-level tolerances, creating a tight leak-proof seal with the engine block and thermostat.
One-piece cast hose nipples provide higher strength compared to pressed-in designs, preventing nipple breakage and coolant loss under high engine vibration conditions. The anodized surface treatment improves corrosion resistance against ethylene glycol-based coolants, extending service life compared to untreated aluminum housings.
This thermostat housing cover fits Kia commercial diesel models including Bongo K2500, K2700, K2700II, K3000, K3000II, K3000S, K3600, K4000S, as well as Pregio and Besta models produced between 1996 and 2015. Replacing cracked, warped or leaking original thermostat housings with this unit can eliminate coolant loss, engine overheating and inconsistent cabin heating, preventing costly engine damage. Engineered for the operating environment of commercial diesel engines, the housing has a normal service life of 80,000-120,000 km under regular maintenance conditions.
Common root causes include aged and brittle rubber gaskets or O-rings from prolonged heat exposure, cast aluminum housing cracking from thermal cycling fatigue, corrosion of mating surfaces from contaminated coolant, or stripped mounting bolt threads from over-tightening. Visible coolant seepage, coolant accumulation on the engine block, and steady coolant level drop are typical symptoms. Never open the coolant system when the engine is hot to avoid severe burns.
A stuck closed thermostat causes sudden overheating, with the upper radiator hose remaining cold while the engine is hot. A stuck open thermostat leads to slow warm-up, cold cabin heater output and increased fuel consumption. Blocked internal passages from coolant sediment can also cause uneven engine temperature. In most applications, the thermostat is installed inside the housing assembly, so it is recommended to replace the thermostat when replacing the housing.
Broken hose nipples cannot be reliably repaired. Attempts to epoxy or weld the nipple will fail under engine operating pressure and vibration, leading to catastrophic coolant loss and engine overheating. Replace the entire 0K62Z-10150C assembly immediately when hose nipple damage is found.
Free sample programs are available for qualified distributors, and third-party quality inspection is accepted before shipment. The product supports minimum order quantities of 500-1000 units, with packaging options including genuine standard packaging, neutral packaging and brand packaging for different commercial procurement requirements.
