How to Change the Coolant in a 2019 GAS GAS XC250R
Shop parts for your ride now!Changing the coolant in your 2019 GAS GAS XC250R is crucial for maintaining optimal performance and prolonging the life of your engine. This high-performance two-stroke enduro bike uses a liquid-cooled system, making routine coolant flushes a must for riders demanding reliability on the trails. Follow these model-specific steps to ensure a thorough and safe coolant change.
What You Need
- Compatible coolant (consult your owner's manual for specifications)
- Basic socket set
- Flathead screwdriver
- Drain pan
- Rags for cleanup
- Funnel
- Gloves and eye protection
Step 1: Preparation
Ensure your bike is cool before starting–hot coolant can cause serious burns. Set your XC250R on a stand and remove the radiator shrouds using a socket wrench. Place the drain pan beneath the water pump on the right side of the engine to catch old coolant.
Step 2: Draining the Old Coolant
Locate the coolant drain bolt at the water pump housing. Carefully loosen it with a socket and allow the coolant to drain completely. For a more thorough flush, remove the radiator cap (located on the left side of your bars) to let air in as the coolant drains. Inspect the drained fluid for contaminants—milky or sludgy fluid could indicate an internal gasket issue.
Step 3: Inspect and Clean Components
This is the ideal time to check your radiator hoses for softness, cracks, or leaks. The radiator cap's rubber seal should be intact with no signs of wear. Clean any debris from the radiators with compressed air or a soft brush (never use a pressure washer, as fins are delicate).
Step 4: Adding New Coolant
Reinstall the drain bolt, ensuring the copper washer is in good condition and torqued to factory spec. Use a funnel to slowly pour fresh coolant into the radiator up to the filler neck. Gently tilt the bike left and right to help evacuate trapped air bubbles—air in the cooling system reduces efficiency and can cause overheating.
Step 5: Bleeding the System
Start the bike with the radiator cap off and let it idle for a couple of minutes, keeping an eye on coolant level. As air bleeds from the system, the level may drop, so top off as necessary. Once the fluid stabilizes, replace the radiator cap securely.
Step 6: Final Checks
Reinstall the radiator shrouds and inspect the entire system for leaks. After your first ride, check the coolant level again and inspect for any drips.
2019 GAS GAS XC250R Model Notes
- The XC250R uses a lightweight, high-capacity cooling system ideal for technical terrain—always use high-quality, pre-mixed or mix-to-spec coolant to protect aluminum components.
- Factory torque specs for bolts are vital. Over-tightening can damage threads and seals, while under-tightening can cause leaks.
- This model's water pump has a dual lip seal for additional protection. If you ever spot oil in your coolant or vice versa, consult a professional as these signs point to a possible seal or gasket issue.
- For regular riding, check coolant before each outing and always use protective gear and proper tools for every step.
Keeping your 2019 GAS GAS XC250R's coolant fresh doesn't just protect your engine—it protects your entire ride. Follow these steps and you'll be ready to conquer the trails with confidence.
