Excessive Heat in Cabin
Have a 2018 GT-C and am getting a lot of heat from the engine when no a/c is on w/top down. Is this normal? Also how many bars is normal in the heat indicator gauge?

Coolant heat gauge should be in the middle; but I don’t think that would heat up the cabin. The engine would fail well before you felt the heat, and you’d see the steam, if it was a coolant issue.

HVAC Off
I turn the HVAC off
altogether when I drive w/top down. I see you saying that 8 bars is normal for the engine heat gauge. That’s what I have as well, but still feel I am getting a lot of heat down near my legs,
especially near the transmission/drivetrain. I had a 2014 Jaguar XKR Supercharged w/510 hp and don’t remember it giving off this much heat.

I am not feeling any high temps in our cabin. Normal and similar to our other/past MB’s.
That said, GT models are running hot on engine//trans. It’s not unusual to see 220 degree engine temps and the transmission temps near that in traffic on a summer day.
Nothing to be concerned on the GTC but in other cars I would be worried if the temp exceeds 180…

Bought this girl as a CPO w/<4K miles. I appreciate all of the responses here but I guess I just wanted to know if I s/b concerned that I thought it was running hot, w/the heat coming through into the cabin near my right leg when driving.

I would have someone check and make sure the heat shields are in place.

Can you feel hot air coming out of the vent near your leg. Can you change the direction of the air so that air blows out of just the upper(dash) vents and then the windshield vents and see if the hot air follows? You may have a diverter that is stuck in the lower position in the heat position?
