How to Change the Coolant in a 2020 Sherco 500 SEF FACTORY
Changing the coolant in your 2020 Sherco 500 SEF FACTORY is an important maintenance procedure that ensures your bike's high-performance four-stroke stays protected from overheating and internal corrosion. Here's a step-by-step guide made exclusively for MotoSport.com customers, plus critical notes unique to your model.
Preparation – What You Need
- Fresh, high-quality motorcycle coolant (do not replace with plain water)
- Basic hand tools (ratchet, sockets, screwdriver set)
- Catching pan for old coolant
- Funnel and clean shop towels
- Distilled water (only if your coolant requires mixing)
- Protective gloves and eyewear
Step 1: Access the Cooling System
- Ensure the engine is completely cool before starting.
- Remove any bodywork or shrouds necessary to access the radiator and radiator cap.
Step 2: Drain the Old Coolant
- Position your catch pan under the water pump area.
- Identify the coolant drain bolt on the lower portion of the water pump or radiator (check your model-specific location in your owner's manual).
- Slowly open the radiator cap to relieve any pressure, then remove the drain bolt and allow the old coolant to fully drain.
Step 3: Flush the System (Optional but Recommended)
- If you see any debris or discoloration, flush the system with distilled water.
- Reinstall the drain bolt, fill the radiator with distilled water, run the engine briefly, then drain again.
Step 4: Reinstall Drain Bolt
- Replace any sealing washer on the drain bolt if necessary and torque the bolt to specification (generally around 10 Nm, but always verify for your model).
- Wipe away any spilled coolant before proceeding.
Step 5: Add New Coolant
- Mix your coolant if necessary using only distilled water—never tap water to avoid mineral deposits.
- With a funnel, pour coolant into the radiator until it reaches the filler neck.
Step 6: Burp the System
- Leave the radiator cap off and start the engine.
- Carefully run the bike while gently rocking it and blipping the throttle. This helps trapped air escape (known as 'burping').
- Add more coolant if needed to top off to the filler neck.
Step 7: Final Checks
- Reinstall the radiator cap securely.
- Fill the overflow reservoir to the upper line if your bike is equipped.
- Start the engine and double-check for any leaks.
- Reinstall any previously removed bodywork.
- Dispose of the old coolant properly, following local environmental guidelines.
