I have a 2018 chevy equinox 92k miles that is eating coolant like mad..almost 5 quarts a week. I can never see a puddle or leak and there's no white smoke out the exhaust, its not over heating as i keep replacing coolant. Theres nothing under the oil cap and it's dry and clean. The onboard system says pressures and Temps are good when I'm driving 30 to 75 psi and the fan kicks on at 208 like it's supposed to while rarely running a bit after shutting off the car. I do however see drops of coolant near the water pump but I feel like it might just be leaking down that way from somewhere else. It has gotten a bit louder since it started. Any idea what's causing it. No codes at all btw
