How to Change the Coolant in a 2000 Suzuki RM80
Shop parts for a 2000 Suzuki RM80 Dirt Bike.
Routine coolant changes keep your 2000 Suzuki RM80's two-stroke engine running cool, especially during hot moto sessions. This model uses a simple liquid cooling system, but following a step-by-step process ensures optimal results and helps prevent overheating & corrosion.
What You Will Need
- Fresh coolant formulated for motorcycles (silicate-free, non-caustic)
- Distilled water (for flushing)
- Drain pan
- Basic hand tools (typically 8mm and 10mm sockets)
- Rags for cleanup
- Protective gloves
Step-by-Step Coolant Change Process
-
Preparation
Ensure the engine is cool before beginning. Remove the seat, side panels, and if installed, the skid plate for easy access to the radiator and water pump. Place your drain pan beneath the water pump area. -
Drain Old Coolant
Locate the water pump drain bolt (usually at the bottom of the pump housing on the right engine cover). Remove this bolt carefully and allow coolant to fully drain. Remove the radiator cap to help fluid flow freely. Dispose of old coolant according to local regulations; avoid pouring it into the ground or drains. -
Flush the System
Pour distilled water into the radiator until it drains clear from the pump. This helps remove old coolant and any built-up contaminants. Do not use tap water due to potential mineral deposits. Once clear, reinstall the water pump drain bolt snugly. -
Add New Coolant
With the drain bolt tightly secured, carefully pour new coolant into the radiator up to the base of the filler neck. Tip the bike side-to-side to release trapped air bubbles. If equipped, open any bleeder screws on the radiator until coolant appears without air, then retighten. -
Check for Leaks & Bleed Air
Reinstall the radiator cap. Start the engine and let it idle for a few minutes; blip the throttle carefully to circulate coolant and release air. Stop engine and allow to cool fully. Remove the cap and check the level again, topping off if necessary. Repeat until the level stabilizes. -
Reinstall Components
Replace any bodywork and skid plate. Wipe down any spilled coolant.
2000 Suzuki RM80 Notes
- This RM80 model features a basic two-radiator system located on each side of the frame for optimal heat dissipation during aggressive riding.
- Inspect radiator hoses for cracks, swelling, or leaks each time you service the coolant. Replace any hoses showing age or damage.
- Coolant intervals: Change coolant at least once a year, or more frequently with high racing hours or after mud rides.
- This chassis and cooling design was shared with RM85 models, so keep tabs on small radiators and the integrity of the radiator cap to prevent overheating in tough conditions.
Pro Tips
- Never mix coolant types (such as using automotive antifreeze with motorcycle coolant)–always use a compatible formula for aluminum motorcycle radiators.
- Always bleed the system to eliminate air pockets, which can cause erratic running temperature and risk engine damage.
