Hyosung has issues with the supply chain globally affecting certain parts being available to distributors but , good job on replacing the thermostat
Next, you will need a FAN SWITCH , see the topic below:
Get a bottle of MOTUL FACTORY LINE RACING COOLANT , it is my most recommended coolant for any Liquid cooled motor.
Download the service manual on this forum , so it will show you how to deal with the temperature issues and how to test your TEMPERATURE Sensor
So remember, 3 things to check:
- FAN Switch (Link above ^ )
- Temperature SENSOR (Measure values using multimeter to make sure it is within OEM spec on service manual)
- Thermostat (again, get water in a bowl at boiling 80c degrees, and see if it pops open) , then put it back inside the engine & check for leaks.
Last thing to check, make sure the WATER PUMP is OK. If the pump is dead, it won’t be able to move coolant around your cylinders to the radiator to cool it.
Water pump is very hard to get these days , so be ready to repair it if necessary but hopefully there is no issue with it.
