Shop parts for a 2019 Husqvarna 701 Enduro Dirt Bike.
Changing the coolant on your 2019 Husqvarna 701 Enduro is essential for long-term performance and engine health. This premium dual-sport model features a high-output liquid-cooled engine, so regular coolant maintenance protects vital components and helps prevent overheating even during demanding off-road rides. Unlike older off-road bikes, the 701's sealed cooling system and integrated overflow tank require attention to both system bleeding and reservoir levels. Below you'll find a proprietary MotoSport.com step-by-step procedure created for Husqvarna's 701 platform.
Tools – Supplies & Prep
- Metric socket set (10mm required)
- Allen wrenches/hex keys
- Drain pan
- High-quality motorcycle engine coolant (silicate-free, safe for aluminum engines)
- Funnel and clean rags
- Protective gloves and eyewear
1. Let the Engine Cool Completely
The 2019 701 Enduro cooling system is pressurized when hot—never open the radiator or reservoir cap immediately after use. Wait until engine and radiator are fully cool to the touch to avoid burns and spray.
2. Remove the Seat – Access Panels
- Remove the seat using your ignition key or tools as your model requires.
- Remove the left side fairing/cover to access the radiator cap and overflow reservoir.
3. Place Catch Pan – Open Radiator Cap
- Set a drain pan underneath the engine, directly below the water pump area.
- Carefully unscrew the radiator cap (located on the left side under the shroud) to relieve pressure and enable rapid draining.
4. Locate & Remove the Coolant Drain Bolt
- On the lower right side of the engine (water pump housing), locate the coolant drain bolt (10mm socket).
- Loosen and remove this bolt. Allow all coolant to fully drain into the pan. For faster draining, you may gently tilt the bike side to side.
5. Drain the Overflow Reservoir
- Disconnect the overflow hose at the bottom of the reservoir and allow any remaining coolant to drain out. Wipe up any spilled fluid immediately—coolant is toxic to pets and the environment.
6. Inspect & Refit Seals
- Check the drain bolt and its sealing washer for damage. Replace the washer if worn or flattened to prevent leaks, then reinstall and torque the drain bolt to the manufacturer's specs.
7. Fill with Fresh Coolant
- Slowly pour new coolant into the radiator neck until full, pausing to allow air bubbles to escape. Tap the hoses gently to release trapped air.
- Add coolant to the overflow reservoir as well. Ensure the cold-level mark (MIN/MAX) is met.
8. Bleed the System
- With the radiator cap off, start the engine and let it idle for a few minutes. Keep an eye on the coolant; as bubbles emerge, the level may drop—top up as needed.
- When all bubbling stops, switch off the engine and refit the radiator cap securely.
9. Final Checks
- Reinstall all panels and the seat.
- Go for a brief, gentle test ride. Once cooled, re-check the overflow tank and radiator level. Top up if necessary.
2019 Husqvarna 701 Enduro – Model Note
This generation 701 Enduro is equipped with a Nikasil®-coated cylinder, aluminum radiator, and purpose-built overflow tank. Coolants with silicates or improper additives can cause premature cylinder or water pump wear. Always use coolant specifically rated for aluminum and appropriate for extreme off-road/dual-sport operation. Proper coolant intervals and regular flushes are crucial, as the 701 engine works at higher thermal loads than traditional dirt bikes. Dispose of all used coolant at a certified recycling facility.
Keep your 701 Enduro running strong by trusting MotoSport.com for OEM-quality parts and maintenance upgrades with every service.
