Shop parts for a 2007 Suzuki RM85L Dirt Bike.The 2007 Suzuki RM85L remains a favorite among youth racers and trail riders for its robust two-stroke performance and manageable ergonomics. To keep your RM85L powering through laps and trails, routine coolant replacement is essential for optimal engine temperature control and long-term reliability. Follow this proprietary MotoSport guide for a safe, thorough coolant change, including notable details for this specific model.
What You Need
- Fresh 2-stroke compatible coolant (never mix with automotive antifreeze)
- Socket wrench set (8mm for water pump bolt)
- Drain pan
- Funnel
- Distilled water (for flushing)
- Clean shop towels
- Mechanic gloves and safety glasses
Important: Model-Specific Notes for the RM85L
- The RM85L features a high-revving 2-stroke engine susceptible to overheating during high-rpm use or if the coolant is old – regular changes are critical.
- Inspect radiator hoses, cap, and water pump for cracks or leaks during service – this 2007 model may have aging rubber components.
- Always use a non-silicate, phosphate-free coolant formulated for motorcycles to avoid water pump or gasket wear.
Step-by-Step Coolant Change Instructions
-
Preparation:
- Ensure the bike is cold before starting service.
- Position your RM85L on a stable, level surface with the front wheel straight.
-
Remove Plastics (If Needed):
- Remove the right side number plate or any plastics obstructing access to the radiator and water pump, using a socket wrench as needed.
-
Drain the Coolant:
- Locate the 8mm drain bolt at the lower water pump cover (right side of engine).
- Place a drain pan beneath, then loosen and remove the drain bolt.
- Now remove the radiator cap to allow air in, letting coolant flow out completely.
- Dispose of old coolant according to local hazardous waste rules.
-
Flush the System:
- To prevent mineral buildup, pour distilled water into the radiator using a funnel.
- Reinstall the drain bolt temporarily, add distilled water, then remove drain bolt again to flush any remaining residue.
- Repeat until only clear water exits. Avoid tap water due to mineral and sediment risks.
-
Refill with Coolant:
- Reinstall and tighten the drain bolt securely.
- Slowly fill the radiator with high-quality motorcycle coolant. Leave a little space for expansion but fill up to the base of the filler neck.
-
Bleed Air from the System:
- Tilt and gently rock the bike side to side to help expel trapped air bubbles.
- Wait several minutes. Top off if the level drops and reinstall the radiator cap.
-
Warm Up & Final Checks:
- Start the engine and run it at idle until warm, then allow it to cool fully. Recheck and top up the radiator and coolant reservoir if necessary.
- Inspect under the bike for leaks near the water pump and hose connections.
Maintenance Frequency – What 2007 RM85L Owners Should Know
- Suzuki recommends changing coolant every year, or sooner if riding in harsh conditions or racing regularly.
- Check the radiator cap seal and replace if it shows signs of wear. Pressure loss can cause overheating or poor coolant flow.
- Flushing the cooling system is especially important after top-end rebuilds to remove possible metal or gasket debris.
Routine coolant changes protect your RM85L from overheating and engine damage, keeping it ready for race day and every trail ride. For all replacement cooling parts, radiators, hoses, and fresh coolant – trust MotoSport as your dedicated dirt bike headquarters.
