If you want a heavy-duty, high-efficiency aluminum radiator built for the extreme heat of long haul trucking and heavy construction cycles, choose CFOTIXAR Water Tank Radiator; if you need a direct replacement unit specifically engineered for Genie boom lifts and aerial work platforms, choose XYohykai Water Tank Radiator.
• CFOTIXAR: Built with louvered fin technology and 3-row cooling capacity for superior heat dissipation in CAT E-series excavators; trade-off is its massive physical footprint which requires precise fitment checks.
• XYohykai: Designed as a stable, easy-installation drop-in for Genie AL and RL series boom lifts with part number 866110GT; trade-off is it lacks the aggressive 3-row fin density of the CFOTIXAR, focusing on standard reliability rather than maximum thermal efficiency.
• Who picks CFOTIXAR: Operators of Caterpillar E320C, E318C, and E319C machines who need to run engines hot without overheating during demanding excavation or logging shifts.
• Who picks XYohykai: Maintenance crews managing Genie AL4000D2, TML-4000, and RL4 series lifts who prioritize exact OEM part matching and quick installation over upgraded cooling specs.
The CFOTIXAR Water Tank Radiator is not just a replacement part; it is an upgrade designed for environments where cooling performance is non-negotiable. This unit targets owners of Caterpillar CAT 320C, E320C L, E318C, and E319C models who are tired of stock radiators failing under sustained load. The engineering here leans heavily into raw thermal management. With a three-row configuration and louvered fin technology boasting between 14 to 16 fins per inch, this radiator pushes coolant capacity well beyond original equipment manufacturer (OEM) specifications. In real-world terms, that means when your engine is working overtime moving earth or processing timber, this unit pulls heat away from the block significantly faster than standard units.
The build quality speaks to durability in harsh conditions. This isn't flimsy sheet metal; it is constructed to withstand vibration and pressure spikes common in off-road machinery. Every seam is 100% Tig welded, ensuring there are no weak points where leaks might develop over time. The inclusion of a zinc alloy cap and a strengthened billet filler neck adds another layer of protection against corrosion and mechanical stress. If you are running a machine that spends eight hours a day in the mud and dust, these features translate directly to fewer breakdowns and less downtime.
However, this level of performance comes with specific spatial requirements. The dimensions are substantial: an overall height of 38 1/5 inches and a width of 33 6/7 inches, excluding the neck and cap. The inlet and outlet are both 2 inches. While this ensures a perfect match for the designated Caterpillar models, it leaves no room for error regarding clearance. You cannot simply swap this in without verifying that your engine bay can accommodate the increased thickness of a three-row core compared to a two-row OEM unit. It is a precision component that demands precision installation. This product is ideal for the serious fleet manager or owner-operator who understands that a slight increase in initial cost pays off in longevity, but it is strictly for those specific CAT excavator models.

In contrast, the XYohykai Water Tank Radiator serves a different segment of the heavy equipment market entirely. Its primary function is restoration and maintenance for Genie aerial work platforms. Specifically, it fits the Genie AL4000D2, TML-4000, RL4, AL4L, AL5L, AL5000, AL5GT, RL4000D2, AL8000HT, and RL4000 series boom lifts. If you manage a fleet of scissor lifts or boom lifts, this is likely the part you need to keep your workers safely elevated. The design philosophy here focuses on stability, ease of installation, and fast response times, ensuring that your lift gets back to work quickly after a repair.
The standout feature of the XYohykai unit is its adherence to the original part number, 866110GT and 866110. For fleet managers, this compatibility is critical. When you order a replacement, you need certainty that it will bolt up correctly without needing custom fabrication or modification. The product description emphasizes "easy installation," which suggests a straightforward swap process that minimizes labor costs. In the world of boom lifts, time is money. A mechanic should be able to remove the old unit and install this new one without fighting with mismatched ports or baffled tanks. The unit promises stable performance and high reliability, which are the baseline expectations for safety-critical equipment used at heights.
That said, the XYohykai does not boast the same aggressive thermal upgrades found in the CFOTIXAR. It appears to be a direct functional equivalent rather than a high-performance enhancement. This does not mean it is inferior; it simply means it is optimized for the operating profile of a boom lift, which often involves intermittent lifting rather than continuous, high-torque digging. If you are looking for a part that restores your Genie lift to its factory cooling standards, this is the correct choice. However, if you plan to push a Genie lift beyond its rated capacity or into extreme heat conditions requiring aftermarket cooling, you might find this unit lacks the extra headroom provided by more complex designs.
• Best for heavy-duty heat dissipation → CFOTIXAR Water Tank Radiator. Its 3-row design and louvered fins offer a 35-40% improvement in heat dissipation efficiency, making it superior for engines running at full throttle for extended periods.
• Best for Genie Boom Lift compatibility → XYohykai Water Tank Radiator. It is explicitly engineered for the AL and RL series, ensuring the 866110GT part number matches perfectly for immediate installation.
• Best for structural durability → CFOTIXAR Water Tank Radiator.
• Best for rapid fleet maintenance → XYohykai Water Tank Radiator. The focus on "fast response" and "easy installation" makes it the practical choice for keeping aerial platforms operational with minimal downtime.
• Best for specific Cat Excavator models → CFOTIXAR Water Tank Radiator. It is the only option listed that covers the CAT 320C, E318C, and E319C families with a direct OE standard replacement for part 193-2767.
• Best for general purpose reliability → XYohykai Water Tank Radiator. It offers a stable, reliable solution for standard industrial lifting tasks without the complexity of an upgraded cooling system.
• Best for space-constrained engine bays → Depends on model, but CFOTIXAR requires careful measurement due to its larger 38 1/5" height and 33 6/7" width, whereas XYohykai follows standard Genie dimensions.
• Best for long haul trucking and construction → CFOTIXAR Water Tank Radiator. Its heavy-duty construction and enhanced cooling capacity are better suited for the rigorous demands of long-distance hauling and constant excavation work.
After analyzing the specifications and intended applications, I would choose the CFOTIXAR Water Tank Radiator for anyone operating heavy construction machinery like CAT excavators, particularly for long haul trucking and intense industrial work. While the XYohykai is a solid choice for Genie lifts, the CFOTIXAR represents a genuine engineering upgrade for those who need their equipment to survive the harshest conditions. In my opinion, paying for that extra heat dissipation and weld strength is the smartest investment for maintaining uptime on a Caterpillar rig.
It replaces part numbers 193-2767 and 1932767, so verify your exact machine model before purchasing.
You must cross-reference your existing part number with the listing, which specifies 866110GT and 866110. It is designed for the AL4000D2, TML-4000, RL4, AL5L, and similar Genie boom lift series, so check your old part number first.
According to the specifications, it is crafted to OE standards to ensure a precise fitment. It is a direct replacement that should require no drilling or modifications, provided you have the correct vehicle details entered.
The CFOTIXAR features a 3-row design with louvered fins that improve heat dissipation efficiency by 35-40% compared to OEM specs, while the XYohykai is a standard replacement focused on stability and direct fitment for Genie lifts without explicit mentions of upgraded row counts.
