Heho community,
The second quick-tip 2019 covers the correct cleaning, refilling and bleeding of the cooling system on the KTM 690 models.
Here again the necessary tools or materials:
1. Plastic tray to catch the coolant
2. Protective gloves
3. Safety glasses
4. Coolant e.g. Motocool Factory Line

5th lobe
6. if necessary: Cooling system cleaner eg Radiator Clean300:

Operation and advantages of the closed cooling system:
1. Coolant is not lost after stopping the hot engine, but can expand in the expansion tank.
2. Gas bubbles or gaseous components in the coolant can escape via the expansion tank and thus cause no damage.
3. Steam bubble formation (cavitation) is avoided.
4. Due to the existing overpressure higher temperatures in the cooling system can be driven (over 120 ° C) without the boiling point is reached. Advantage: higher operating temperature when running the engine = better efficiency from the engine.
5. Coolant pump consumes less engine power as it runs in the system without air and does not have to suck in coolant again and again.
