Sun Coast Cycle Sports carries inspected used parts for the 2011-2018 Polaris Ranger Diesel, the only diesel-powered UTV in the Polaris lineup. The Ranger Diesel uses a Kohler or Yanmar three-cylinder diesel engine offering exceptional low-end torque, fuel efficiency, and the ability to run off the same fuel supply as farm and construction equipment. Available in standard and Crew configurations, the Diesel was purpose-built for agricultural, commercial, and industrial applications where diesel fuel availability and long service intervals are priorities. Our Florida technicians evaluate each Ranger Diesel donor, photograph parts under unique SKUs, and ship free within the continental U.S.
Ranger Diesel generation and parts compatibility
| Era | Years | Engine | Power | Key Features |
|---|
| Gen 1 | 2011-2014 | 904cc Kohler 3-cyl diesel | 24 hp | Full-size chassis (shared with Ranger 800 platform); diesel torque for hauling |
| Gen 2 | 2015-2018 | 1028cc Yanmar 3-cyl diesel | 24 hp | New Yanmar engine; Ranger 900-based chassis; Crew variant; multi-power system option |
The Ranger Diesel uses completely unique engines that share no parts with any gasoline-powered Polaris vehicle. The Gen 1 Kohler diesel and the Gen 2 Yanmar diesel are different engines from different manufacturers and do NOT interchange with each other. The diesel engines require diesel-specific maintenance including fuel filter replacement, glow plug service, and diesel-rated oil.
The Ranger Diesel's chassis is shared with the contemporaneous gasoline Ranger of the same era: the Gen 1 shares the Ranger 800 full-size platform, and the Gen 2 shares the Ranger 900 platform. This means many non-engine components (body panels, cab, suspension, brakes, cargo box, wheels, accessories) interchange between the Diesel and the gasoline Ranger of the same era. Only engine, exhaust, fuel system, and engine-adjacent components are diesel-specific.
The Ranger Diesel was discontinued after 2018 as Polaris shifted focus to its electric Ranger platform (Ranger XP Kinetic) for zero-emission work applications.
Common Ranger Diesel failure points and replacement parts
Glow plug failure: Diesel engines require glow plugs for cold starting. Failed glow plugs cause hard starting or no-start conditions in cold weather. Glow plug replacement is a periodic maintenance item, particularly in cold-climate applications.
Fuel system contamination: Diesel fuel is susceptible to water contamination and microbial growth (diesel bug) during extended storage. The fuel filter/water separator requires regular draining and periodic replacement. Contaminated fuel causes rough running, power loss, and potential injector damage.
Diesel particulate filter (DPF) maintenance (where equipped): Later Gen 2 models may include emissions equipment that requires periodic regeneration or cleaning. Restricted DPF causes power loss and warning lights.
Drive belt wear: The diesel engine's high torque at low RPM places sustained stress on the PVT belt during heavy hauling. Belt inspection and replacement is the primary drivetrain consumable.
Cooling system demands: Diesel engines run hotter than their gasoline counterparts. Coolant system health, radiator cleaning, and thermostat function are critical, particularly during sustained heavy-load operation.

Frequently asked questions
Q: Does the Ranger Diesel share parts with gasoline Rangers?
Yes, for most non-engine components. The Diesel shares its chassis with the contemporaneous gasoline Ranger (Gen 1 with Ranger 800, Gen 2 with Ranger 900). Body panels, cab, suspension, brakes, wheels, cargo box, and most accessories interchange. Engine, exhaust, fuel system, and engine-specific wiring are diesel-exclusive and share nothing with gasoline models.
Q: Are Gen 1 (Kohler) and Gen 2 (Yanmar) Ranger Diesel engines interchangeable?
No. The Kohler 904cc and Yanmar 1028cc are completely different engines from different manufacturers with different dimensions, mounting patterns, and specifications. No engine components cross over between Gen 1 and Gen 2 Ranger Diesels. The chassis also changed between generations (800-based to 900-based), so even non-engine parts may not interchange.
Q: Why was the Ranger Diesel discontinued?
Polaris discontinued the Ranger Diesel after 2018 as the company shifted its alternative-fuel strategy toward electric power. The Ranger XP Kinetic (electric) was introduced as the zero-emission option for environmentally sensitive work applications. The diesel's niche market of agricultural and commercial users who needed diesel fuel compatibility did not generate sufficient volume for continued production. Existing Ranger Diesel owners can source chassis and body parts from gasoline Rangers of the same era, while Sun Coast's inventory helps fill the gap for diesel-specific engine components.
