If you want a radiator designed for the rugged, high-reliability demands of Genie boom lifts in tight industrial spaces, choose XYohykai Water Tank Radiator; if you need a direct replacement unit specifically engineered for Caterpillar telehandlers operating in heavy-duty material handling environments, choose YIHETOP Radiator 174-4429.
• XYohykai Water Tank Radiator: Its biggest strength is its specific engineering for Genie boom lift models like the AL5000 and RL4 series, ensuring stable performance and fast thermal response. The trade-off is that it is strictly limited to this narrow ecosystem of aerial work platforms and will not fit other machinery brands. This pick is for fleet managers and mechanics maintaining Genie fleets who prioritize part number precision and installation ease.
• YIHETOP Radiator 174-4429: Its primary advantage is its tailored design for the Caterpillar TH62, TH63, TH82, and TH83 telehandler lines, offering a robust solution for vertical lifting tasks. The limitation is its exclusivity to these specific Cat models, making it incompatible with any other brand or model. This pick is ideal for operators and maintenance crews who rely on Caterpillar equipment for construction and warehouse logistics.
The XYohykai Water Tank Radiator is built around a singular, critical function: keeping Genie boom lifts cool under pressure. When you look at the specifications, this unit is identified by part numbers 866110GT and 866110, which are not generic placeholders but precise identifiers for a specific set of aerial work platforms. It fits a wide array of Genie models, including the AL4000D2, TML-4000, RL4, AL4L, AL5L, AL5000, AL5GT, RL4000D2, AL8000HT, and the RL4000 series. This compatibility list tells me that this component is designed for versatility within a single brand's ecosystem, serving both older and newer generations of boom lifts.
For anyone working in construction, event setup, or facility maintenance where Genie lifts are the backbone of daily operations, this radiator offers peace of mind. The product description emphasizes stable performance and high reliability, which are non-negotiable traits when you are working hundreds of feet in the air. If a cooling system fails during a job, the consequences can be catastrophic for the machine and dangerous for the operator. This unit promises easy installation and fast response times, suggesting that the core design focuses on minimizing downtime. You do not want to spend hours wrestling with a complex fitment process when your schedule is tight.
However, this product is not for everyone. If you own a telehandler from a different manufacturer or a boom lift from a brand other than Genie, this part will not work for you. The part number specificity means there is no room for "close enough" substitutions. If your machine requires a 174-4429 style unit or a different part number entirely, looking at this option is a waste of time. It is a specialized tool for a specialized job. If you are managing a mixed fleet with multiple brands, you will need to keep separate inventory for each brand rather than hoping for a universal fit.

The YIHETOP Radiator 174-4429 serves a very different segment of the industrial market. Its entire existence is defined by its compatibility with Caterpillar telehandlers, specifically the TH62, TH63, TH82, and TH83 models. These machines are workhorses used for moving heavy pallets, loading trucks, and navigating rough terrain on job sites. The part number 174-4429 (also listed as 1744429) is the exact match required for these units. Unlike the broad Genie coverage of the XYohykai unit, the YIHETOP radiator is a dedicated solution for a specific line of telescopic handlers known for their heavy-lifting capabilities.
This radiator is for the operator who needs consistent cooling performance while pushing their telehandler to its limits. Telehandlers often operate in dusty, hot environments where the cooling system takes a beating. A failure here can lead to engine overheating, which is a common issue in high-stress material handling scenarios. By choosing a unit explicitly labeled for the TH62 through TH83 series, you are ensuring that the internal channels and tank dimensions match the original equipment exactly. This precision is crucial because even a slight deviation in fitment can cause leaks or reduced airflow, leading to premature engine wear.
Like the Genie unit, the YIHETOP option has a clear boundary. It is not designed for Genie lifts, nor does it claim to fit other brands. If you are looking for a replacement for a Genie AL5000, this part is irrelevant. It is also not a universal upgrade; it is a direct replacement part. This makes it perfect for a mechanic who knows exactly what they are replacing and wants to avoid the guesswork of cross-referencing part numbers. However, if you have a modified telehandler or a model outside the TH62-TH83 range, you must verify your part number before ordering, as this product is not a one-size-fits-all solution for all Caterpillar equipment.
• Best for Genie Boom Lift Owners → XYohykai Water Tank Radiator. - Best for Caterpillar Telehandler Owners → YIHETOP Radiator 174-4429. If you operate a TH62, TH63, TH82, or TH83, this unit is engineered specifically for those chassis. - Best for Installation Speed → XYohykai Water Tank Radiator. The product notes highlight "easy installation" as a key feature, which is vital for busy shop floors trying to get lifts back online quickly. - Best for Heavy-Duty Material Handling → YIHETOP Radiator 174-4429. Caterpillar telehandlers are often subjected to more continuous, heavy-load cycling than standard boom lifts, requiring a radiator designed for that specific duty cycle. - Best for Part Number Precision → Both are excellent, but they serve different lists. XYohykai covers a longer list of Genie models, while YIHETOP covers a shorter, specific list of Cat models. Neither is superior; they are just targeted differently. - Best for Stability in High Heat → Both emphasize stability, but the application context differs. The XYohykai unit supports aerial work where engine heat buildup can be sudden due to height and wind factors, while the YIHETOP unit supports ground-based heavy lifting where sustained load generates steady heat. - Best for Mixed Fleet Management → Neither. You cannot use one part for both brands. You must purchase the correct unit for each specific machine type. - Best for Back Seat Passengers → While neither product is designed for passengers, the reliability of the XYohykai unit ensures safer operation for the lift operator and any passengers riding in the basket of a Genie boom lift, reducing the risk of breakdowns in elevated positions.
I would buy the XYohykai Water Tank Radiator if I were responsible for maintaining a Genie boom lift, simply because the emphasis on "stable performance" and "fast response" aligns perfectly with the safety-critical nature of aerial work. For back seat passengers, knowing the lift is running reliably without overheating risks is paramount, and this unit's specific fit for models like the AL5000 suggests a level of engineering confidence that reduces uncertainty. However, if my focus was on a Caterpillar telehandler, I would immediately switch to the YIHETOP Radiator 174-4429, as the part number match is the only way to ensure the cooling system handles the unique stress of heavy material handling. In my opinion, the right choice isn't about which brand is better overall, but which one matches the exact machine you are operating today.
The primary difference lies in their vehicle compatibility. The XYohykai unit is designed exclusively for Genie boom lifts, while the YIHETOP unit is built solely for Caterpillar telehandlers. They are not interchangeable.
No, the YIHETOP Radiator 174-4429 is specified for Caterpillar models (TH62, TH63, TH82, TH83) and will not fit Genie boom lifts. Always verify your part number before purchasing.
The XYohykai Water Tank Radiator explicitly markets itself as having "easy installation," whereas the YIHETOP data sheet does not make specific claims about the installation process, focusing instead on part compatibility.
Yes, both are described as reliable replacements for commercial machinery. The XYohykai unit targets industrial boom lifts, and the YIHETOP unit targets heavy-duty telehandlers used in construction and warehousing.
