Genuine Polaris UTV / ATV and Side by Side OEM Water Pumps and Components - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Polaris Shaft Bearing Water Pump, Part # 3515828.

Engineered for Maximum Cooling Efficiency

Your cooling system is the only thing standing between a successful ride and a catastrophic engine failure. The water pump is the heart of this system, responsible for circulating coolant through the engine block and radiator. Because Polaris high-output engines operate under extreme conditions—including mud-clogged radiators, high-RPM technical climbs, and desert heat—having a reliable, factory-spec water pump is non-negotiable.

These Polaris UTV/ATV OEM water pumps and components are designed to meet the exact flow rates and pressure requirements of your ProStar or Turbo engine. Choosing Genuine OEM ensures that every seal, impeller, and shaft meets the strict tolerances required to prevent leaks and maintain thermal stability.

Benefits of Genuine Polaris Cooling Components

  • Precision-Machined Impellers: Designed to move the maximum volume of coolant without cavitating, even at high engine speeds.
  • High-Grade Mechanical Seals: OEM seals are built to withstand the abrasive nature of off-road grit and sand that can prematurely wear out aftermarket versions.
  • Perfect Housing Alignment: Eliminates the risk of "weep hole" leaks caused by the slight casting imperfections often found in budget-tier replacements.
  • Thermal Durability: Materials are tested to resist warping or degrading when exposed to the extreme heat cycles common in UTV and ATV racing or heavy utility work.

Popular Water Pump Parts & Accessories

A complete cooling system service often requires more than just the pump itself. Find these essential components at Witchdoctors.com:

  • Water Pump Rebuild Kits: Includes seals, O-rings, and bearings for a full refresh.
  • Mechanical Seals: The primary defense against coolant mixing with engine oil.
  • Replacement Impellers: Restore flow efficiency lost to erosion or debris.
  • Radiator Hoses / Lines: Heavy-duty silicone or reinforced rubber options.
  • Polaris 50/50 Premixed Coolant: The specific formula required to protect OEM seals.
  • Thermostats & Components: Ensure your cooling system opens and closes at the correct factory temperatures.

Frequently Asked Questions (FAQ)

What are the signs of a failing Polaris water pump? Common symptoms include coolant leaking from the weep hole on the side of the engine, a grinding noise coming from the pump area, or the engine temperature gauge rapidly climbing into the red zone.

Should I replace the mechanical seal when I replace the impeller? Yes. Whenever the water pump is disassembled, it is a best practice to replace the mechanical seal and any associated O-rings to ensure a leak-free transition and prevent oil contamination.

Can I use automotive coolant in my Polaris? We strongly recommend using Polaris-specific coolant. Many automotive coolants contain silicates that can act as an abrasive, damaging the delicate mechanical seals in powersports water pumps.
