How to Change the Coolant in a 2011 Husaberg FE450
Shop parts for a 2011 Husaberg FE450 Dirt Bike.
The 2011 Husaberg FE450 is a high-performance enduro machine, and regular coolant changes are crucial for keeping its advanced engine running cool and protected, whether you're trail riding or pushing hard in competition. Here is a step-by-step procedure, along with model-specific tips, for changing the coolant on your FE450:
What You Need
- Fresh engine coolant compatible with aluminum radiators
- A drain pan
- Socket set or wrenches
- Funnel
- Clean water (distilled for flushing, optional but recommended)
- Clean rags
- Protective gloves
Step-by-Step Guide
-
Let the Engine Cool:
Before starting, make sure your FE450's engine is completely cool. This prevents burns as pressurized coolant can spray when hot. -
Remove Side Panels and Fuel Tank (if needed):
For easiest access to the radiator cap and hoses, remove the seat and side panels using the seat release loop and quick-release fasteners; remove the fuel tank if it obstructs access to the radiator. The 2011 FE450 uses tool-less seat removal for fast service. -
Place Drain Pan and Open Radiator Cap:
Set the drain pan below the water pump or lowest hose connection point. Open the radiator cap to allow air in, so coolant drains freely. -
Drain the System:
Locate the coolant drain bolt on the water pump cover (typically the lowest bolt on the right side of the engine case). Remove it carefully, allowing all coolant to drain. Loosen the radiator hose at the bottom for a more complete drain if desired. -
Flush (Recommended but Optional):
If the coolant is dirty, or you have used a different coolant type previously, flush the system by temporarily reinstalling the drain bolt, filling the system with distilled water, running the engine briefly, then draining again. -
Replace the Drain Bolt and Check Seals:
Inspect the copper washer on the drain bolt for wear or damage; replace if necessary to prevent leaks. -
Refill with New Coolant:
Slowly pour new coolant into the radiator through a funnel. Fill until it covers the radiator fins and is just below the filler neck. Check the owner's manual spec, but typically, coolant should sit approximately 10 mm (0.39 in) above the radiator fins when full. *Note: Use a premixed, non-silicate coolant safe for aluminum. The FE450's high-performance cylinder head and magnesium cases require compatibility with modern coolants.* -
Bleed Air from the System:
Gently rock the bike left and right, then squeeze radiator hoses to help bubbles escape. Run the engine briefly with the radiator cap off, allowing remaining air to exit; top off if needed. -
Reinstall the Radiator Cap:
Secure the radiator cap tightly. Reinstall bodywork and tank if removed. -
Final Checks:
Start the bike and let it idle to operating temperature. Shut it off, allow it to cool, and check coolant level again–add if needed. Inspect for leaks at drain bolt and radiator hose connections.
Owner’s Tips for the 2011 Husaberg FE450
- The FE450’s water pump uses dual seals: one for coolant, one for oil. Watch for leaks from the water pump weep hole—this could mean a worn seal. Replace promptly, as water pump failure can cause coolant contamination of engine oil.
- Always use coolant recommended for modern four-stroke racing engines. Avoid mixing types; cross-contamination can reduce protection and cause deposits in the cooling passages.
- Check your radiator protection and coolant hoses regularly. Off-road riding can damage or loosen hoses, leading to slow leaks or overheating.
- Consider flushing the system more frequently if riding in harsh or muddy environments–mud and minerals can clog radiators, reducing cooling efficiency.
With proper maintenance, your FE450's high-revving engine will keep its cool, no matter how punishing the trail. For the highest quality replacement coolants, radiators, hoses, and maintenance accessories, trust MotoSport.
