How to Change the Coolant on a 2017 Suzuki DR200S: Step-by-Step Guide
Shop parts for a 2017 Suzuki DR200S Dirt Bike.
The 2017 Suzuki DR200S is a dependable trail bike, but keeping its engine at the right temperature is key to longevity & performance. Regularly changing the coolant is an essential maintenance task, particularly since this model relies on a traditional liquid-cooling system to keep the air/oil-cooled engine's temperatures stableespecially during off-road and hot-weather rides.
Tools & Supplies
- Phillips/flathead screwdriver
- Socket set & ratchet
- Drain pan
- Pre-mixed motorcycle coolant (suitable for aluminum engines)
- Funnel
- New sealing washer (recommended for drain bolt)
- Distilled water (if flushing or diluting concentrated coolant)
- Shop rags & gloves
Changing the Coolant: Procedure
- Ensure the engine is cool. The coolant system is pressurized when hot. Never open the radiator cap on a hot engine.
- Remove the seat & side panels for easier radiator access.
- Locate the radiator cap and reservoir. The radiator cap is on top of the radiator; the expansion tank (reservoir) is typically accessible near the frame.
- Loosen the radiator cap, but leave it in place to prevent sudden coolant release while draining. Open the expansion tank cap as well.
- Place a drain pan beneath the water pump/drain bolt found at the base of the engine's cooling circuit.
- Remove the drain bolt (and any related hoses if needed) to allow coolant to drain completely. Use caution — the old coolant can be toxic and corrosive to finishes and the environment.
- To flush (optional but recommended): Reinstall the drain bolt loosely, fill the radiator with distilled water, run the bike at idle for a few minutes, shut off, cool, and drain again. Repeat for thorough rinsing.
- Reinstall the drain bolt using a fresh sealing washer to prevent future leaks. Tighten to manufacturer specification.
- Slowly fill the radiator with new pre-mixed coolant using a funnel to avoid introducing air pockets. Fill until near the base of the filler neck.
- Top up the expansion tank to the upper mark.
- Bleed the system: Start the engine and allow it to idle for several minutes with the radiator cap off. Gently rev and rock the bike to help trapped air escape. Look for bubbles rising from the filler neck.
- Shut off the engine and let it cool. Recheck and top off coolant in both the radiator and the tank if the level has dropped.
- Securely refit all caps, panels, and seat.
- Check for leaks. Monitor your coolant levels during the next few rides, topping up as needed.
Model-Specific Tips for the DR200S
- The DR200S's radiator is compact. Take care not to overfill the system, as excess coolant can lead to overflow especially after the first heat cycle.
- Never substitute general automotive coolant — use only coolant safe for motorcycle engines and aluminum radiators.
- If you notice persistent coolant loss, inspect for possible leaks at the hose connections and the mechanical water pump seal, which is a known maintenance point on this bike after prolonged use.
- Don't neglect flushing: older coolant can cause internal corrosion and affect the DR200S's thermal efficiency on trails.
Final Thoughts
Routine coolant changes on your 2017 Suzuki DR200S protect the engine from overheating and corrosion, ensuring smooth riding year-round. If additional maintenance is needed or worn parts appear during coolant service, refer to the OEM parts diagram for model-specific replacements.
