Yes, everything was ok until not.
Coolant temp started rising during a hot track event (>86F), I've stopped and found coolant all over the engine bay. Oil temp was ok (230F max) but coolant spiked to 240.
I've refilled the radiator (once to car cooled down), and still used it for like a couple of weeks as a daily with no problems. I've tought that was a combination of the hot day, and coolant not in best shape.
A couple of days ago, I've used the car for a "canyon drive" driving hard and I had the same issues, so there is absolutely a problem
The exhaust gas pushes all the coolant out of the radiator and the car starts overheating, at least that is what I think.
No contamination on coolant or oil by the way.
