How to Change the Coolant in a 2006 Suzuki RM85L
Shop parts for a 2006 Suzuki RM85L Dirt Bike.Changing the coolant on your 2006 Suzuki RM85L is a straightforward process that ensures efficient engine cooling and optimal dirt bike performance. Regular coolant replacement protects internal engine parts from overheating and corrosion–crucial for this high-revving, race-developed two-stroke. The RM85L, with its long-travel suspension and light frame, thrives on proper maintenance to deliver the crisp throttle response and reliability riders demand.
What You Need
- Fresh engine coolant (at least 570 ml, check manufacturer recommendations for type and mix ratio)
- Drain pan (appropriate for catching old coolant)
- 8mm socket and ratchet (for drain plug at the water pump)
- Clean funnel
- Distilled water (for flushing, if desired; avoid tap water to prevent mineral buildup)
- Gloves and safety glasses
- Soft rags or towels
Important Safety Tips for RM85L Owners
- Never open the radiator cap when the engine is hot–hot coolant and steam can cause serious injury. Only begin this procedure with a completely cool engine.
- Always dispose of old coolant in accordance with local regulations.
Step-by-Step Coolant Change Process
- Stabilize the Bike: Place your RM85L upright on a stand or block to keep the chassis level. This ensures accurate draining and refilling.
- Remove Radiator Cap: With the engine cool, carefully remove the radiator cap to relieve any residual pressure.
- Drain Old Coolant: Position your drain pan under the water pump. Use an 8mm socket to remove the drain bolt at the bottom of the water pump. Allow all coolant to flow out.
Optional flush: Pour distilled water into the radiator, let it drain out completely to help remove any leftover coolant residue. Avoid tap water due to mineral content. - Reinstall Drain Plug: Once drained, securely reinstall the drain bolt. If you removed any radiator hoses during flushing, reconnect them now.
- Refill with Coolant: Insert a funnel and pour new coolant into the radiator until full (capacity: 570 ml). Pause occasionally to let air escape. Fill until coolant reaches the base of the filler neck.
- Bleed Air from the System: Tilt the bike side to side gently to help trapped air escape.
- Check & Secure Radiator Cap: Double-check the coolant level, then firmly reinstall the radiator cap.
- Warm Up and Recheck: Start the engine and let it idle for several minutes. Shut off and let the engine cool fully, then recheck the coolant level in the radiator. Top off if needed. Inspect for any leaks at the drain bolt or hoses.
Additional Tips for the 2006 RM85L
- Use only recommended coolant types to avoid potential gasket or seal failures.
- Regularly inspect the radiator cap for wear or damage–the RM85L requires a cap release pressure of 0.95–1.25 kgf/cm² (13.5–17.8 psi).
- Inspect hoses for cracks or leaks each time you change the coolant. The RM85L's compact cooling system means a minor leak can quickly affect engine temperature.
- Suzuki recommends annual coolant replacement for peak system efficiency.
Routine cooling system maintenance is a key reason why the RM85L stays strong on the track or trail. For quality replacement parts and fluids tailored for your 2006 Suzuki RM85L, MotoSport delivers everything enthusiasts need to keep this legendary two-stroke running cool and clean mile after mile.
