Regularly changing the coolant in your 1996 Suzuki DR350 is essential for optimal performance and longevity. This simple maintenance guide, designed just for MotoSport.com riders, delivers easy-to-follow, model-specific steps to keep your DR350 running cool all season long.
What Makes the DR350's Cooling System Unique?
The 1996 DR350 is a rugged, air- and oil-cooled single-cylinder dual sport. However, the DR350S and DR350 dirt versions use a small liquid-based cooling loopsometimes called an oil coolerrather than a full-on radiator setup. This means the coolant discussed here applies to models with external oil coolers. Most DR350 models do not have traditional engine coolant or radiators but rely on oil as the main cooling medium. If your particular DR350 is a rare version that uses coolant (for example, a custom build or unique variant), these steps cover the general process. Always check your owner's manual for specifics before proceeding.
Tools & Supplies Needed
- Drain pan
- Socket set (8mm for water pump bolt, if equipped)
- Fresh, motorcycle-specific coolant (never use straight tap water or automotive coolant)
- Distilled water (for rinsing, if necessary)
- Funnel
- Shop towels and gloves
Step-by-Step Coolant Change Guide
- Ensure engine is cold. Never remove the cap or start draining the system while hot—serious burns may result.
- Remove the skid plate or protective panels for easy access to the water pump/stator cover (if equipped).
- Place drain pan beneath the water pump drain bolt. (On the DR350, if equipped, this is typically an 8mm bolt at the base of the engine's cooling loop.)
- Remove the radiator or filler cap. This allows air in and coolant to drain more completely.
- Remove the drain bolt and let the coolant flow out. Tilt the bike gently side to side to remove as much old fluid as possible. Dispose of old coolant responsibly—never pour it onto the ground or down a drain.
- If flushing is needed (recommended), reinstall the drain bolt, fill the system with distilled water, and repeat the drain process. Always use distilled water. Avoid tap water to prevent mineral deposit buildup.
- With the drain bolt securely replaced, fill the cooling system with fresh coolant up to the recommended level (usually the base of the filler neck).
- Reinstall the filler/radiator cap.
- Start the bike and let it idle. As the engine warms, air bubbles will exit the system. Shut off and let it cool. Check the coolant level; top off if needed.
- Replace all panels and check for leaks. Dispose of all used fluids properly. Ride safely.
Notable DR350 Maintenance Tips
- Most DR350s are primarily air- and oil-cooled—always confirm if your model features any liquid cooling. If it does not, focus on regular oil changes and external oil cooler maintenance instead.
- Regularly inspect hoses, caps, and sealing gaskets for wear.
- If you ride hard in hot conditions or off-road, coolant and oil may degrade faster—consider shorter intervals for changes.
