Hi Guys, I'm Ash from south Africa... I own a 1999 model Honda ballade 150i, I have it for 5 years now and all of a sudden its the heat gauge goes past the middle, I've replaced the thermostat and services the car about two weeks ago.. It's been behaving arite but it comes to operating temp kwik and now it bubbles in the water bottle.. Any ideas guys please 🙏
