Changing the coolant on your 2013 Honda XR650L is essential maintenance to keep your engine running cool and performing at its peak. This guide will walk you through the process step-by-step, highlight special considerations for the XR650L, and keep your weekend rides smooth and worry-free.
Why Change the Coolant?
Over time, coolant breaks down, losing its ability to dissipate heat and prevent corrosion. For dirt bikes like the XR650L, especially if ridden in hot or harsh conditions, fresh coolant prevents overheating and protects vital engine components from internal wear.
What You Need
- Compatible ethylene glycol-based coolant (avoid silicate-based products)
- Distilled water (if using concentrate)
- Socket set and screwdrivers
- Catch pan
- New crush washer for the drain bolt (Honda part #90463-ML7-000 recommended)
- Rags and gloves
Instructions – 2013 Honda XR650L Coolant Change
- Ensure engine is completely cool. Never remove the radiator cap when the engine is hot.
- Remove side panels and any obstructing plastics. Use a socket or screwdriver as required.
- Locate the radiator cap on the left side of the bike. Remove the cap to relieve pressure.
- Find the coolant drain bolt (typically low on the water pump, right side of the engine). Position a catch pan under it.
- Remove the drain bolt and old crush washer. Allow coolant to fully drain.
- Inspect and clean the drain bolt. Install a new crush washer for a secure seal.
- Reinstall the drain bolt. Tighten to manufacturer torque specification.
- Flush (optional but reommended): Fill radiator with distilled water, run the engine for a few minutes (monitor temperature), then drain. Repeat as needed until drained water runs clear.
- Slowly refill the radiator with new coolant. If using concentrate, mix with distilled water as specified.
- Rock the bike gently from side to side to help work air bubbles out of the system.
- Start engine and let idle for 2–3 minutes. Watch coolant level, add more if needed. Snap throttle a few times to help purge air.
- Stop engine and check coolant level again. Top off as needed. Install radiator cap securely.
- Reinstall all panels, check for leaks, and clean any spilled coolant.
Special Tips for XR650L Owners
- The XR650L has a proven air-&-oil cooled engine with a compact radiator. It’s vital to use only ethylene glycol-based coolant – never silicate-based formulas – to avoid damaging the aluminum radiator and pump.
- If the coolant hasn’t been changed in 2 years or 24,000 miles, prioritize this service. Dirt, mud, and high temperatures can shorten coolant life.
- Don’t forget the new crush washer every coolant change. This helps ensure no leaks at the drain bolt.
- After the initial ride post-service, check coolant level once more as air pockets may still work themselves out.
