Changing the coolant in your 2022 Sherco 500 SEF FACTORY is a vital part of keeping your engine running at its best. This model, known for its performance and reliability, uses a high-efficiency cooling system that demands proper care and attention. Follow this proprietary MotoSport guide to ensure a smooth coolant replacement and maintain optimal temperature regulation for your Sherco.

Required Tools – Supplies

  • 4-stroke motorcycle coolant (specifically not plain water or any non-approved fluids)
  • Socket set and basic hand tools
  • Drain pan
  • Funnel
  • Rags or cleaning cloths
  • Protective gloves

Preparation Steps

  • Ensure the engine is completely cool to avoid burns.
  • Park the motorcycle on a level surface with a stable stand.
  • Remove the saddle and fuel tank to access the radiators, referencing your user manual for step-by-step tank removal and cable routing. Be careful not to pinch cables or hoses during removal and installation.

Draining the Old Coolant

  • Locate the radiator cap on the left radiator—remove it slowly to relieve system pressure.
  • Position your drain pan beneath the lowest point of the cooling system. On the 500 SEF FACTORY, this is typically the radiator lower hose or the water pump drain bolt.
  • Loosen the clamp and pull the lower hose free, or unbolt the drain bolt to allow coolant to flow into your pan. Be careful to catch all used coolant safely for environmentally responsible disposal.
  • Remove the overflow tank if equipped, drain and, if needed, clean it out with water and a soft brush.

Flushing the System (if needed)

  • If the drained coolant was especially dirty, flush the system by filling it with distilled water, running the engine briefly (with the cap on), and draining again. Repeat until water runs clean. Do not leave water in the system; always finish with coolant.

Inspect Components

  • Check radiator hoses for any cracks or brittleness by gently squeezing them. Replace as needed to avoid leaks or bursts down the line.
  • Tighten all hose clamps and ensure proper routing during reassembly to prevent rubbing or pinching.

Adding New Coolant

  • Reconnect the lower radiator hose or install the drain bolt, tightening clamps securely.
  • Using a funnel, pour the manufacturer-recommended coolant into the radiator fill neck slowly to minimize trapped air. Fill the overflow tank to the correct mark as well.
  • With the radiator cap off, start the engine and let it idle for several minutes to circulate coolant and expel air. Gently rock the bike side to side to help release remaining air bubbles.
  • Top off the coolant as the level drops. Once stable, reinstall the radiator cap.

Final Steps – Checks

  • Reinstall the fuel tank, routing cables and hoses properly per manual directions to avoid pinching or obstructions. Reinstall the saddle securely.
  • Start the engine again and let it warm up fully. Check for leaks around hoses, radiator, and drain points.
  • Check coolant level once the engine has cooled completely, topping off as needed.

Notes Unique to the 2022 Sherco 500 SEF FACTORY

  • This model uses a high-performance cooling system with Synerject injection. Only use approved coolants – never use tap water or random antifreeze, as improper fluids may cause system damage or sensor malfunctions.
  • Watch for corrosion or scale inside the radiators during coolant change; this can point to poor maintenance or improper fluids in the past.
  • Always verify proper hose routing and clearance when reinstalling all parts. The aluminum radiators and connectors are precise—routing mistakes can cause issues during operation.
