Description:

Race-Ready Aluminum Cooling That Won’t Quit

Crafted from premium aircraft-grade aluminum, the Pundimo radiator combines lightweight agility with serious heat-shredding power. Its patented tube-and-fin design packs 16 high-density fins per inch – 35% tighter than conventional radiators – paired with 3/8″ optimized coolant channels that create 25% more surface area. The result? 40% faster heat dissipation and 1,500 additional cooling surfaces to tame even turbocharged engines, whether you’re dominating lap times or crawling in summer traffic.

Engineered for Abuse, Built to Last

This radiator means business. The military-grade aluminum core shrugs off corrosion from road salt and harsh weather, while vacuum-brazed seams eliminate leak risks found in welded models. We’ve added 30% more coolant capacity to smooth out extreme temperature swings – think desert highways to mountain passes – and trimmed 5 lbs off the weight for better handling. No plastic end tanks, no flimsy joints – just clean aluminum engineering that handles curbs, vibrations, and years of daily driving.

Why Drivers Upgrade to Pundimo:

✔Tall 1-inch fins pull 18% more airflow at speed

✔Direct OEM fit – installs in 90 minutes with basic tools

✔Dense 14-16 FPI design outpaces basic aluminum units

✔Overbuilt core withstands 300+ HP builds

From weekend warriors to daily drivers, this is the smarter way to stay cool. Lighter than steel, tougher than plastic hybrids, and designed to outlast your ride – because when temperatures climb, compromise melts away.

• [Radiator Fitment]: This radiator is specifically designed to fit Kubota G/GR/T/TG series lawn tractors including G2160, G21HD, G21LD, GR1600EC2, GR2100, GR2100EC2, GR2110, GR2120AU, and Kubota Z series zero – turn mowers such as ZD18, ZD18F, ZD21, ZD21F, ZD221; with OE/OEM Part Number: K2110-85010
• [Radiator Specifications]: This radiator is made of aluminum with a high – performance racing spec 2 – Row – tube core racing design. The overall height is 18 1/2 in., width is 14 3/5 in., and thickness is 3 in. The core height is 13 7/10 in., width is 12 4/5 in., and thickness is 1 1/2 in. The inlet and outlet diameters are both 1 1/8 in
• [Highly Efficient Cooling]: The Pundimo radiator core is crafted from lightweight aluminum. Its tube and fin design is engineered to drastically increase the surface area. This, in turn, allows heat to dissipate way more efficiently. The aluminum construction not only cuts down on weight but also plays a crucial role in enhancing the overall cooling performance, making it a top – notch choice for various applications where efficient heat transfer is key
• [Proven Performance]: The Pundimo radiator has an increased coolant capacity, which means it can handle racing applications with ease. It’s built to be more resilient against temperature swings. Made from aircraft – grade aluminum, this radiator outshines other common alloys when it comes to corrosion resistance. The brazed core technology used ensures peak performance and reliability, so you can count on it to keep your engine cool, race after race. Whether it’s the intense heat of a long – distance race or the stop – and – go of a circuit track, the Pundimo radiator has got you covered
• [All – Aluminum Radiator]: The Pundimo radiator features a high – density core with cooling rows spaced just 3/8″ apart. This design allows for 25% more rows in the core compared to standard aluminum radiators. The cooling fins, which make up a full inch of the total surface area, have 14 to 16 fins per inch. That’s around 1,500 more cooling fins than what you’d find in typical aluminum radiators. All these features combined lead to a significantly improved heat dissipation capacity. So, if you’re looking for a radiator that can really get the job done and keep your system running cool, the Pundimo all – aluminum radiator is the way to go
