Hey guys, Became a proud Lexus owner this January. It’s a 2018 is300, the car had 100,000 kms on it, I’ve driven around 40,000 kms this year, runs like a charm. Had no issues whatsoever so far, A couple of days back I just popped the hood to check the fluid levels and was shocked to see the coolant reservoir was empty! Took a look around and found a leak, I’m not sure which part is this.Please help me out, looks like thermostat but I don’t know for sure!
