Fault Warning SPN 110 FMI: 1 ??
Plugs will tell you if you are burning coolant but consuming the whole tank in 20 seconds would be hydro locking your engine if it was getting in a cylinder or 2.
Sounds like a hose is leaking, but would expect to see coolant in the hull.
Trying to think if any closed loop coolant hose dumps straight to exhaust/water jacket.
Leak in heat exchanger? That would dump closed loop coolant.

Could there be air in the lines from the coolant going low? Then when you fill and run it, it fills that void and lowers the bottle level?
Does not address how you are loosing coolant, but if you keep refilling the bottle, I would expect to see something in the hull.
Also, I think Zach told me the had to clear that clear the computer code when it happened to me. But that was after I got that heater fitting fixed.2018 Supra SL400

Knox, to clarify - are you saying that you can’t keep engine temp stable after it first drops a bit when drinking the coolant you’ve added?
Also, you are a Supra now, correct? Do you have the heater loop pump in same spot as the moombas? That was the source of my leak/failure but wasn’t loosing coolant near that fast.2016 Mojo Surf
