I have a 2011 Hyundai Equus ultimate package with 124,000 miles. A few weeks ago I refilled my power steering fluid and noticed I had almost no coolant. My car doesn’t have a coolant sensor and my vehicle wasn’t showing any signs of overheating so I had no idea. I topped off on that too and a week later I checked again, the power steering fluid stayed the same but the coolant was down to the half way point. I figured since it was almost empty before, the coolant loss was just due to it cycling through. I topped it off again and then 2-3 weeks later I decided to take another look and now it’s almost empty again. The car isn’t leaking anything from the bottom, I removed the skid plates to check if there was any evidence of a leak, still nothing. I suspected an internal leak so checked the radiator/radiator cap and the water pump, still nothing. I’ve looked at everything in the engine bay and the exhaust, its completely dry. The car isn’t driving abnormally, making noises, producing abnormal vapor from the exhaust or overheating. I genuinely have no idea where the coolant is going but since so much Is disappearing in a short amount of time, it has to be going somewhere.
