Keeping your 2019 Husqvarna TE300i running at its peak demands regular coolant changes. This step-by-step guide, built for TE300i owners, details everything you need to know to flush and replace the coolant efficiently–and highlights unique factors about your ride.
Why Change the Coolant?
Fresh coolant maintains engine temperatures, prevents corrosion, and helps your TE300i perform at its best. Neglected coolant can cause overheating, internal damage, and expensive repairs.
What You'll Need
- Approved motorcycle coolant (do not mix coolant types)
- Drain pan
- 8mm or 10mm wrench (check bolt size for your model)
- Funnel
- Clean rags
- Safety gloves and eye protection
Before You Start
- Work on a completely cold engine. Hot coolant is hazardous.
- Ensure the bike is upright–a lift or stand works best for full drainage.
Step-by-Step Coolant Change
-
Locate the Drain Bolt
The primary drainage point is a bolt on the right side of the cylinder, above the power valve. This is a design shared by Husqvarna two-strokes of this generation, including the TE300i. Place your drain pan below this area.
Note: Loosen the radiator cap before removing the drain bolt. This allows air in and ensures complete draining. -
Drain the Old Coolant
Remove the coolant drain bolt carefully and allow coolant to fully empty into your drain pan. Be patient–the TE300i's dual radiators empty in parallel, so ensure both are fully drained.
Once the flow slows, lean the bike gently from side-to-side to remove as much old coolant as possible. -
Inspect and Clean
Inspect the old coolant for debris or rust–signs of internal issues. If needed, flush the system with distilled water and repeat the drain. Tighten the drain bolt securely after cleaning up any residual coolant. -
Refill with New Coolant
Using a funnel, slowly pour fresh recommended coolant into the radiator until it reaches the bottom of the cap neck.
Squeeze the radiator hoses gently to release trapped air bubbles. -
Bleed and Top Up
With the radiator cap still off, set the bike upright and start the engine for about 30 seconds. Shut off and let it settle. Top off the radiator if the level has dropped.
Replace and secure the radiator cap. -
Check for Leaks and Test Run
Run the engine up to full operating temperature. Inspect all connections for leaks, and allow the system to cool before checking the coolant level again and topping off if needed.
Model-Specific Tips for the 2019 Husqvarna TE300i
-
The TE300i features electronic fuel injection with specific temperature sensors. Ensure no coolant contacts electrical connectors.
- Never mix different coolant types: Only use coolants approved for aluminum radiators, and flush thoroughly if switching brands or formulations.
- The drain bolt crush washer should be inspected or replaced each coolant change for a proper seal.
- The coolant system capacity is approximately one liter, but always verify by filling to the recommended level in your rider's manual.
Environmental & Safety Reminders
- Dispose of old coolant responsibly–do not pour it down drains or onto the ground.
- Wear gloves and wash any coolant off skin immediately.
A well-maintained cooling system keeps your TE300i ready for the toughest singletrack. Regular attention to coolant changes helps prolong engine life and performance.
