Antifreeze level dropping from high mark to low mark in about 3 months. Normal?

[donnietTA]

I filled it back up about 3-4 months ago and each morning I check it and it sits at the low line on the reservoir. Can’t find any leaks or evidence on the ground.
I have the V-6 , anyone else notice this?

I'd recommend getting a block tester to check for exhaust gasses in your coolant.

My challenger had an almost imperceptible head gasket leak, a couple small signs that were easy to ignore and assume we're nothing, but the block tester did in fact show exhaust gasses coming from the coolant.

It's also possible that you have a leak somewhere difficult to spot, especially if it's slow, such as heater core.

The manual says it should be between the min and max lines when cold, I’ll add some in the AM if needed. Yes, I have the latest premix that I picked up from my dealership.

Did you say you've added some before and it's decreased again? What level did it start at before you added more? Or if you didn't add any, what level did it start at?

two days after I bought it I bought the antifreeze and added to the tank because it was on the min line. Guy at dealership said he keeps his filled at max lines. I have only added to it once back in may. Hopefully I don’t have a leak.
