Regular coolant changes are essential for the continued performance and longevity of your 2021 Husqvarna 701 Enduro. This guide walks you through each step of the coolant replacement process – tailored specifically for this high-performance dual-sport, which features a liquid-cooled, single-cylinder engine that relies on fresh coolant for optimal temperature regulation.
Before You Begin
- Coolant capacity: Approx. 1.2 liters (always check the owner's manual for confirmation).
- Recommended coolant: Use high-quality, silicate-free motorcycle coolant compatible with aluminum engines. Avoid mixing different coolant types.
- Tools needed: 10mm socket, drain pan, funnel, protective gloves – and patience, as the system can trap air easily.
Step-by-Step Coolant Change Procedure
-
Ensure the Engine is Cool
Changing coolant on a hot engine can cause burns. Allow the bike to cool completely. -
Remove the Seat and Left Side Trim Panel
Use your key and appropriate tools to remove the seat and side trim for access to the radiator and the expansion reservoir. -
Open the Radiator and Reservoir Caps
Remove the radiator cap first (located at the top of the left radiator) and then the reservoir cap. This allows air in, so coolant can drain quickly and smoothly. -
Position the Drain Pan and Remove the Drain Bolt
Place a drain pan under the engine, near the water pump cover on the right side. Use a 10mm socket to loosen and remove the coolant drain bolt. Expect the coolant to flow rapidly once the suction is broken. -
Fully Drain the System
Tilt the bike gently from side to side if needed to help remove old coolant from corners of the engine and radiators. -
Inspect Seals and Hoses
Examine the drain bolt washer, radiator hoses, and fittings for signs of wear or leaks. Replace any damaged components before proceeding. -
Reinstall the Drain Bolt
Clean the bolt and washer, then securely reinstall. Do not overtighten. -
Refill with Fresh Coolant
Pour the correct type and amount of coolant into the radiator until full. Then top off the expansion reservoir to between the min and max marks. -
Bleed the Cooling System
Air in the system can cause hotspots and overheating. With the radiator cap off, start the engine and let it idle. As air bubbles rise and escape, the coolant may drop – continue topping up as needed. Once no more bubbles emerge, shut off the engine and carefully reinstall the radiator cap. -
Check for Leaks and Verify Coolant Level
Run the engine until warm and inspect for leaks, paying special attention to hose joints, the water pump, and under the starter motor (a known leak area on these bikes). When the bike cools down, recheck the coolant levels in the radiator and reservoir, topping off if necessary.
Notes Specific to the 2021 701 Enduro
- The 701's compact design can trap air during refilling, leading to potential overheating. Take extra time during bleeding and avoid rushing this step.
- Some owners have reported leaks in the region near the starter motor. If you notice coolant pooling in this area after a coolant change, inspect nearby hoses and the water pump weep hole for any signs of leakage.
- Always use a torque wrench when tightening the drain bolt and hose clamps to prevent damage to threads or cracking of the pump cover.
- Dispose of old coolant properly – it is toxic and must not enter storm drains or the environment.
Properly maintaining your cooling system ensures maximum longevity and performance for your Husqvarna. The 701 Enduro's advanced engine management means even minor overheating can impact reliability, so strict adherence to the service schedule is crucial.
