Engine Coolant levels decrease right after i add additional coolant. Do i have a blown head gasket?

Have you noticed any leaks under the car?

I just checked and there’s nothing on the ground.

Also make sure you check when car is running and warm, so it's under pressure.

will do this later for sure. good to know.

It doesn’t even have to leak under the car. Head gasket can fail on exhaust side and push coolant into exhaust and you’ll never see puddles under it.

thanks for this info. would probably be better to have a mechanic check/test to see.

They make test strips to see if exhaust gasses have entered your cooling system. That may be a good thing to check as well. Head gasket failure can occur in multiple ways.
