I have the Robispec radiator/oil cooler combo and noticed last night that my coolant after driving had been low when hot, just at the minimum mark. The coolant temps were normal, but the radiator fans were running at full, which made me think something was abnormal. I added some distilled water and we'll see how it goes.

Today was able to lift the car and noticed some coolant at the plastic access door on the passenger side underneath the car, so I'm hoping it's not a major leak. The drain plug has some residue so I'm going to try and remove the front bumper sometime this weekend or next to check out what could be the culprit. I have 19k miles, 5k miles since the radiator was installed.

Update:
Determined that the drain plug was the source of the leak. I was able to tighten it about 1 full turn. While the drain plug was loose, my coolant temps read over obd2 were 205-215F. After tightening the drain plug, temps were back at 190F, which was normal. Coolant wasn't exceeding the 1.3bar radiator cap since it was escaping out the drain.
