What is normal coolant loss?

[JL120daysinservice]

Nope, appears to be normal thermal expansion & contraction. The level at operating temp is what I use as reference, and it didn't change all summer. With the weather cooling I'll be monitoring the level.

I see, looks like I’ll be doing the same, thank you for getting back to me

Mine consumed about a gallon a year for 2 years. At first I couldn’t find where it was going, until (to my relief) I found a drip under the radiator (not a head gasket). I let it go for over a year, just adding a splash here and there. It was leaking where the plastic end tank meets the aluminum core on the radiator. I was all set to go to swap radiators over the summer…..but the leak stopped. The area where it had been leaking has gotten so crusty from evaporated coolant, that it scabbed itself over. It hasn’t lost any coolant since. I’m leaving it as is until it start leaking again.

Maybe mine will scab over, if not I'm only adding about a pint a year at the most

I am confused on this. I have a '21 Sport S with a 2.0 and I have never added any coolant in the 38 months I have had my baby. Any coolant usage is not normal. If there is a known issue with this, that is concerning. What engine are people having coolant issues with? This 2.0 has been a rockstar. Anyone with a V6 wanna race?
