The best choice depends on what “400 x 600 radiator” means in your search: the supplied products include a 400 mm PC liquid-cooling radiator and vehicle radiators for models with 400 or 600 in their names, but none is confirmed as measuring exactly 400 x 600 mm. The Alphacool is the closest match for PC cooling; WORLDMOTOP suits certain Suzuki GSR 400 and 600 motorcycles; and JAVIK and SFriding offer ATV or UTV replacements. Check the dimensions and exact model fit before ordering.
| Product | Best for | Key distinction |
|---|---|---|
| Alphacool NexXxoS Monsta | PC liquid-cooling builds | 400 mm copper radiator |
| WORLDMOTOP Aluminum Radiator | Specified Suzuki GSR models | GSR400 and GSR600 fitment |
| JAVIK Polaris Sportsman Radiator | Listed newer Sportsman models | Broad year and model fitment |
| SFriding CFMoto Radiator | CFMoto 600 CF600 Z6 | Replacement for OEM 9060-180100 |
| JAVIK Polaris 1240045 Radiator | Specified older Polaris ATVs | OEM number 1240045 |
Alphacool NexXxoS Monsta Full Copper 400mm Radiator
Best for: PC builders looking for a 400 mm radiator for a custom liquid-cooling system. The listing identifies it as a 400 mm model and specifies copper for the end chambers, water channels, and cooling fins. That makes it the most direct match in this selection for a search focused on a 400 mm cooling radiator.
Why it was selected: Its stated 400 mm size and all-copper construction distinguish it from the vehicle-specific replacement parts below. Limitation: The supplied product details do not confirm a 600 mm dimension, thickness, port layout, or case fit. Verify those measurements and system requirements before purchase.
WORLDMOTOP Suzuki GSR400/600 Radiator
Best for: Owners of the specified Suzuki GSR400 or GSR600 motorcycles seeking a replacement radiator. WORLDMOTOP lists CNC aluminum construction and describes the part as a direct bolt-on replacement requiring no modifications. The product title gives a 2004–2012 range, but buyers should verify their precise model year and application.
Why it was selected: It is directly relevant if “400 x 600” refers to a motorcycle model with 400 or 600 in its name. Limitation: The supplied details do not give radiator dimensions or installation instructions. Confirm fitment with the motorcycle’s exact configuration rather than relying on the model names alone.
JAVIK Radiator for Polaris Sportsman Models
Best for: Owners of listed Polaris Sportsman 400, 450, 500, or 570 models, along with certain Sportsman 6×6, X2, and Touring versions and a Hawkeye 325. The fitment information is unusually detailed, including years and some specific editions. JAVIK describes the part as an OEM replica made for abrasion and corrosion resistance.
Why it was selected: It covers multiple Polaris models associated with the 400 and 500 search terms. Limitation: Fitment excludes some editions and varies by year. Check the full application list and OEM references (1240520, 1240305, 1240152, or 1241477) before ordering.
SFriding Aluminum Radiator for CFMoto 600
Best for: CFMoto 600 CF600 Z6 owners whose model matches the listing. The radiator is described as an aluminum water-cooling unit with an aluminum core and tank. It replaces OEM number 9060-180100, which provides a useful cross-check when matching a replacement.
Why it was selected: It is specifically identified for CFMoto 600 CF600 Z6 models. The listing claims cooling capacity about 30%–40% higher than a standard radiator; treat that as a seller-provided specification, not an independently verified result. Limitation: The details do not provide dimensions or clarify vehicle-year coverage. Confirm the OEM number and physical fit.
JAVIK Radiator for Older Polaris ATVs
Best for: Owners of certain 2000–2004 Polaris Sportsman, Magnum, Xpedition, Worker, ATP, or Diesel 455 models. This JAVIK radiator is listed as an OEM replica with OEM number 1240045 and is described as abrasion- and corrosion-resistant.
Why it was selected: It gives buyers with older Polaris 400 or 500 ATVs a separate fitment option from the newer-model JAVIK radiator above. Limitation: The listed applications include edition-specific exceptions, especially for 2004 models. Match the year, trim, and OEM number before selecting it.
Buying Guide: How to Choose a 400 x 600 Radiator
Do you mean physical dimensions or a vehicle model?
“400 x 600” can describe radiator dimensions, while product searches may also use engine or vehicle model numbers. The supplied details confirm a 400 mm length for the Alphacool PC radiator, but do not establish that any product measures exactly 400 by 600 mm. For a size-based search, compare the full width, height, thickness, and connection details with your system’s requirements.
What should vehicle owners verify?
Start with the exact make, model, year, trim, and edition. For the Polaris options, check the specified application and OEM number; for the CFMoto radiator, compare OEM 9060-180100; for the Suzuki part, confirm the GSR model and year. A shared “400” or “600” label alone does not establish compatibility.
Which material or design details matter?
The Alphacool listing specifies copper components for a PC liquid-cooling radiator. The motorcycle and ATV listings describe aluminum construction. Material alone is not enough to determine suitability: fit, intended cooling system, dimensions, and connection layout must also match.
How should you compare replacement listings?
- Match the product’s exact application or part number to your equipment.
- Check every year and trim exception in the fitment details.
- Confirm measurements directly when the search depends on a 400 x 600 mm size.
- Separate seller-stated performance claims from independently verified specifications.
- Ask the seller or consult equipment documentation if a critical measurement or fitment detail is missing.
Frequently Asked Questions
Is any listed radiator confirmed to measure 400 x 600 mm?
No. The supplied information identifies the Alphacool product as a 400 mm radiator but does not confirm a 600 mm second dimension for any item.
Which option is for PC liquid cooling?
The Alphacool NexXxoS Monsta is the PC-oriented product in this selection. Its listing describes a 400 mm full-copper radiator.
Which products are for vehicles with 400 or 600 in the model name?
The selection includes a WORLDMOTOP radiator for specified Suzuki GSR400 and GSR600 motorcycles, plus ATV or UTV replacement radiators for listed Polaris and CFMoto models.
Can I choose a radiator based only on the model number?
No. Verify the full model, year, trim or edition, and part number. Products with similar model numbers can have different fitment requirements.
What is the fastest way to check Polaris fitment?
Compare your ATV’s exact year and edition with the product’s application list, then cross-check the OEM number where available. The two JAVIK products cover different Polaris applications.
