Best Radiator Kit For Atv: Relocation and Replacement Options

#1 · Best Overall

1. Wild Boar Honda Screen Kit

Best for: Honda mud-riding radiator relocation.

Why it ranks #1: Fits Honda Rancher 420 and Foreman 500 models listed for 2014–2019, relocating the OEM radiator onto the front rack in a perforated 12-gauge steel box.

Moving the OEM radiator onto the front rack is the defining feature of this screen-style kit. It places the radiator up and out of mud and water for Honda Rancher 420 and Foreman 500 models from 2014–2019, while retaining the stock radiator.

The relocation moves the existing radiator rather than replacing it, so the kit suits owners wanting to reposition their stock cooling component. Its perforated 12-gauge steel screen-style box has a black powder coat and is intended to keep mud and water away from the radiator. Keeping the radiator cleaner supports the stated aim of helping the engine run cooler. Fitment is specifically listed for 2014–2019 Rancher 420 and Foreman 500 models, not as a universal rack accessory.

Skip it if you need a replacement radiator rather than relocation; this kit works with the OEM unit on listed Honda models.

Honda Rancher 420 and Foreman 500 owners who want the stock radiator raised away from mud should consider this relocation kit. Its listed fitment is restricted to 2014–2019 machines, and the OEM radiator is retained.

#2 · Best Polaris Relocation

2. Wild Boar Sportsman Relocation Kit

• Package Dimensions: 20 x 16 x 8 in

Best for: Sportsman mud-protection relocation.

Why it ranks #2: Designed for Polaris Sportsman 450 and 570 models from 2021 onward; includes a front-rack radiator box, coolant hoses, and mounting hardware.

A front-rack relocation for the OEM radiator is the core of this Wild Boar kit, moving it away from mud and water on Polaris Sportsman 450 and 570 models from 2021 onward. The listed package includes a radiator box and bracket, coolant hoses, and mounting hardware.

The perforated 12-gauge steel box and bracket mount the stock radiator on the front rack, helping keep mud and debris away from the cooling fins and making cleaning easier. Since it works with the OEM radiator, the kit changes its position rather than supplying a new core. Coolant hoses and mounting hardware are included in the stated kit contents, supporting the relocation workflow. Fitment excludes Touring models, an important limit for Sportsman buyers to check.

Skip it if you own a Touring model or want a replacement radiator; this kit relocates the OEM unit on specified Sportsman models.

Owners of non-Touring Sportsman 450 or 570 models from 2021 onward seeking protection from mud around the radiator are the intended buyers. It repositions the OEM core, so it is not a replacement radiator.

#3 · Best Bundled Extras

3. Wild Boar Honda Light Bar Kit

• Package Dimensions: 20 x 16 x 8 in

Best for: Honda rack relocation with light bar.

Why it ranks #3: Relocates the OEM radiator for listed Honda Rancher 420 and Foreman 500 models and bundles a Red Deer logo plate with an 11-inch light bar.

This bundle combines a front-rack radiator relocation kit with an 11-inch light bar and bolt-on Red Deer logo plate. It moves the stock radiator away from mud and water on 2014–2019 Honda Rancher 420 and Foreman 500 models, adding lighting to the same rack-area setup.

The screen-style box relocates the OEM radiator onto the front rack, where the listing says it stays out of mud and water and cleaner for cooling. Perforated 12-gauge steel with a black powder coat forms the enclosure. The bundled 11-inch light bar and bolt-on Red Deer plate distinguish it from the basic relocation kit and add rack-mounted components. Because the stock radiator is retained, this package addresses placement rather than replacing a damaged cooling core.

Skip it if you need a new radiator core or do not want the included light bar and logo plate; this bundle relocates the stock unit.

Rancher 420 and Foreman 500 owners from 2014–2019 who want radiator relocation and a bundled light bar are the target. The stock radiator remains in use, so this is not a replacement-core purchase.

#4 · Best Fan Combo

4. COOLINGBEST Ranger Radiator Kit

• Package Dimensions: 21.25 x 17.25 x 7.75 in
• Weight: 11.77 lb

Best for: Polaris Ranger replacement radiator.

Why it ranks #4: A direct-fit aluminum replacement for listed Polaris Ranger 400, 500, and 800 models, supplied with an electric fan, shroud, and thermostat.

A TIG-welded aluminum, direct-fit radiator kit pairs the cooling core with an electric fan shroud and thermostat. It gives owners of listed 2010–2014 Polaris Ranger 400, 500, and 800 models a replacement assembly intended for drop-in installation rather than a universal radiator adaptation.

The specified 15 3/4-by-12 1/2-inch core and 1-inch inlet and outlet provide concrete sizing details for checking the replacement against the Ranger cooling setup. CNC-machined filler neck and cap accompany the TIG-welded construction, while the included fan shroud and thermostat make this a kit rather than a bare core. Its direct-fit claim supports a simpler replacement workflow, but compatibility is limited to the listed Ranger years and variants.

Skip it if you need a radiator for another ATV family; this listing names Polaris Ranger models from 2010–2014 only.

Ranger owners seeking a complete replacement assembly can consider this core, fan-shroud, and thermostat combination. Check that the model and year fall within the listed fitment; its direct-fit claim does not extend to other ATV families.

5. JAVIK Polaris Radiator

• Package Dimensions: 17.32 x 17.13 x 3.74 in
• Weight: 4.84 lb

Best for: Broad Polaris ATV radiator replacement.

Why it ranks #5: Covers numerous listed Polaris Sportsman and 570 variants, with OEM reference numbers provided; confirm the exact edition and year before selecting.

This replacement radiator lists fitment across numerous Polaris Sportsman generations, including specified 400, 450, 500, and 570 versions, plus selected Hawkeye models. That range makes it relevant to owners seeking a direct replacement, provided their exact year, edition, and model designation match the detailed application list.

The fitment listing spans selected Sportsman 400, 450, and 500 variants from 2004 onward and multiple Sportsman 570 versions, including 6×6 and X2 models. It also specifies exceptions, such as the 2015 ACE Edition exclusion, so checking the exact machine designation matters before installation. The package is listed as one radiator, making this a replacement component rather than a relocation kit with a rack box, hoses, or mounting assembly.

Skip it if you have a 2015 Sportsman 570 ACE Edition or need a relocation kit; this listing is for a radiator replacement.

Polaris owners whose exact Sportsman or Hawkeye year and edition appear in the fitment list are the right audience. Verify the detailed application, especially listed exclusions; the package is a radiator, not a relocation assembly.

6. FSMOTO TRX450R Radiator Kit

• Weight: 6 lb

Best for: Honda TRX450R aluminum replacement.

Why it ranks #6: A full-aluminum radiator with silicone hose and cap for Honda TRX450R models listed for 2004–2009; described as a direct replacement without modifications.

A full-aluminum radiator paired with a silicone hose defines this FSMOTO replacement for 2004–2009 Honda TRX450R models. Its direct-replacement listing says no modifications are needed, while the included radiator cap makes it a more complete component package than a bare radiator core.

The radiator’s all-aluminum core and tank are joined using vacuum brazing for the core and TIG welding for the tanks, with no epoxy specified. Those construction details matter to buyers replacing a radiator on the listed TRX450R years. A silicone hose and radiator cap are included, and the direct-replacement, no-modification claim supports a straightforward swap. Professional installation is recommended, so buyers should account for that guidance when planning the repair.

Skip it if you own a Honda outside the 2004–2009 TRX450R range; this replacement is listed specifically for those models.

TRX450R owners from 2004–2009 seeking an aluminum radiator package with hose and cap are the intended buyers. The fitment is specific to that model range, and professional installation is recommended.

7. TRKIMAL Red Oil Cooler

• Package Dimensions: 10.94 x 4.29 x 4.02 in
• Weight: 2.38 lb

Best for: Small-engine oil cooling kit.

Why it ranks #7: An aluminum oil-cooling kit for listed horizontal engines from 50cc to 140cc, including Chinese-made pit-bike applications; it is not a standard ATV coolant radiator.

An aluminum-alloy oil cooler is the central feature of this kit, with the material described as supporting thermal conductivity without burdening the cooler. Its stated applications span horizontal 50cc–140cc engines and Chinese-made pit bikes, making it relevant to small-engine ATV and quad owners.

The listing names Loncin, Zongshen, Lifan, Shineray, and Yinxiang horizontal engines from 50cc through 140cc, plus Chinese-made pit bikes such as Kayo, Apollo, Bosuer, and Xmotos. That broad engine-family coverage helps buyers assess whether it suits a small-engine setup before installation. Aluminum alloy is specified for the cooler, with thermal conductivity identified as its cooling benefit. The product is an oil cooler kit, not a replacement radiator for a Polaris or Honda ATV.

Skip it if you need a replacement coolant radiator for a full-size ATV; this is an oil cooler for listed small horizontal engines.

Small-engine pit-bike and quad owners with one of the listed horizontal engine families are the intended audience. Treat it as an oil-cooling kit, and do not choose it as a replacement for a machine’s coolant radiator.

8. TRKIMAL Yellow Oil Cooler

• Package Dimensions: 10.47 x 4.33 x 4.21 in
• Weight: 2.38 lb

Best for: Small-engine oil cooler in yellow.

Why it ranks #8: Shares the listed 50–140cc horizontal-engine applications and aluminum construction of the red version, but cools engine oil rather than replacing an ATV radiator.

This TRKIMAL kit pairs an aluminum-alloy oil cooler with a yellow radiator-kit designation for listed horizontal engines from 50cc to 140cc. Its stated application includes Chinese-made pit bikes such as Kayo, Apollo, Bosuer, and Xmotos, making engine-family compatibility the key selection point.

The listing names Loncin, Zongshen, Lifan, Shineray, and Yinxiang horizontal engines across 50cc, 70cc, 90cc, 110cc, 125cc, and 140cc sizes. That specificity can help a small-engine owner check application before fitting the cooler. Aluminum alloy is described as supporting thermal conductivity and cooling efficiency. The kit is presented as easy to install, though no detailed installation steps or vehicle-specific fitment chart are supplied, so the named engine families remain the practical guide.

Skip it if you need a full-size ATV coolant radiator; this kit is an oil cooler for listed small horizontal engines.

Small-engine quad and pit-bike owners with a listed horizontal engine are the right audience for this oil-cooling kit. Check that the engine family matches; the listing does not position it as a full-size ATV coolant radiator.

9. YedaHcy YX Oil Cooler

• Package Dimensions: 11.81 x 7.87 x 1.57 in
• Weight: 1.5 lb

Best for: YX engine oil-cooling replacement.

Why it ranks #9: Targets YX 140, 150, and 160 PIT PRO trail and quad applications with an aluminum alloy and ABS cooler, but is an oil cooler, not a coolant radiator.

A replacement oil cooler specifically names YX 140, 150, and 160 applications, including Thumpstar, PIT PRO, trail quad, and off-road motorcycle use. Its aluminum-alloy and ABS construction gives owners a listed material combination to consider when replacing a worn cooler.

The listing presents this as a direct replacement for an old or worn-out oil cooler, which frames its role as a component swap rather than a complete radiator relocation. Its named YX 140, 150, and 160 engine applications help narrow compatibility, and the Thumpstar reference adds a specific use case. The stated goal is keeping motor temperature within the normal operating range while reducing engine load. Buyers should base selection on the listed engine family and application.

Skip it if you need a coolant radiator or your engine is outside the named YX applications; this listing specifies an engine oil cooler.

Owners of listed YX 140, 150, or 160 pit and trail machines, including Thumpstar applications, are the intended buyers. It is an oil cooler replacement, so confirm the engine application rather than treating it as a coolant radiator.

#10

10. NutriEss YX Oil Cooler

• Package Dimensions: 11.81 x 7.87 x 1.57 in
• Weight: 1.5 lb

Best for: YX pit-bike oil cooler.

Why it ranks #10: A compact oil-cooler listing for YX 140, 150, and 160 applications; its stated 245 x 75 x 30 mm size does not make it a standard ATV radiator kit.

An aluminum-alloy and ABS oil cooler with a listed 245-by-75-by-30mm body is aimed at YX 140, 150, and 160 engines. The product description emphasizes oil cooling under high-demand riding, giving pit-bike and trail-quad owners a compact component to assess against their setup.

The stated cooler dimensions and 45mm center-to-center mounting-hole spacing give buyers concrete measurements to compare with their installation location. Aluminum alloy and ABS are the listed materials, while the description identifies oil cooling and temperature control as the intended operating benefits. Its applications name YX 140, 150, and 160 pit, trail, and off-road use. The listing does not provide a complete vehicle-specific fitment chart, so the stated dimensions and engine family are central to the selection decision.

Skip it if you need a vehicle-specific radiator replacement; this product is an oil cooler listed for YX 140, 150, and 160 engines.

YX-powered pit-bike, trail-quad, and off-road riders seeking an oil cooler are the relevant audience. Compare the stated dimensions and mounting-hole spacing with the installation location; this is not a full vehicle fitment chart.
