What Makes the 2023 FX350 Unique?
- Stay Cool Under Pressure: The 2023 FX350 features a large center frame tube channeling coolant through the chassis for consistent flow, reducing system pressure and helping regulate temperature even in extreme conditions.
- Compact, Advanced Engine: Repositioned components, improved cylinder head design, and a 14.6:1 compression ratio demand regular cooling system service for maximum performance and longevity.
Before You Start: Prepare Your Workspace
- Always allow the engine to cool completely before starting to prevent burnsnever open any part of the cooling system when hot.
- Gather necessary tools: 8mm or 10mm wrenches, drain pan, funnel, measuring cup, and fresh, model-approved coolant.
- Position the bike upright and securely on a stand.
- Wear gloves and eye protection; immediately change clothing if coolant makes contactethylene glycol-based coolant is hazardous.
Step-by-Step Coolant Change Process
- Remove the Skid Plate or Panels (if equipped):
This step may not be necessary for all setups, but it provides easier access to the water pump and radiator drain bolts. - Locate the Radiator Cap:
The cap is typically on the right side near the steering head. Remove it slowly once the bike is cool to relieve any residual system pressure. - Find the Drain Bolt:
Look for the coolant drain bolt at the bottom of the water pump cover on the right side of the engine. Place the drain pan underneath to catch old coolant. - Loosen and Remove the Drain Bolt:
Fully loosen the bolt and allow coolant to completely drain out. Carefully tilt the bike if needed for thorough drainage. - Inspect the Washer:
Check the drain bolt washer for wear or damage. Replace if necessary for a sealed, leak-free installation. - Replace the Drain Bolt:
Reinsert the bolt and tighten it to the specified torque setting according to the owner's manual. - Refill with Fresh Coolant:
Using a funnel, slowly add new, manufacturer-approved coolant into the radiator. Fill to the recommended measurement. Avoid air pockets by filling gradually. - Bleed the Cooling System:
To ensure there's no trapped air, gently rock the bike side to side. Top up coolant as needed. Reinstall the radiator cap securely. - Start & Inspect:
Start the engine and let it idle for 2-3 minutes with the radiator cap on. Check for any leaks. Turn off and recheck the coolant level. Top off if necessary.
Other Pro Tips for 2023 FX350 Owners
