Coolant level is ok, triple check that, cold and hot.
Fun starts, but had the impression a few times that mismatch to engage. I mean, at the middle of the gauge, doesnt start, but it does on 3 bars, when i forced cooling it running fast. i couldnt check this right, beacause a lack of time. But is posible beacause the cvt, that engine at 20 km/h runs at 3000 rpm, and at 40 runs at 3300 for example, cooling is improved by speed at similar rpms?
Besides that, never boiled, increases water level or something, and only hit 5 marks one time.
