Leaking antifreeze passenger side below resevoir but not leaking from there. There are little lines that are on frame rail that look to be leaking. What are they? And are they my problem? Doesnt leak out when fluid is low but then there is no heat. Car does not over heat at all. New thermostat also. Please help

Those are probably heater lines going to heater, fill the system and have pressure tested to make sure it is those lines. Tha tis why there is no h eat, low on coolant.

You can feel air /pressure coming out of over flow tube of resevoir. It has the 3/4 heater lines thru the fire wall but the small lines head towards the rear of car. Makes no sense. Do heater cores use 1/4" lines?

If they ae small then it s' probably fuel vapor lines going to rear of car and antifreeze is leaking somewhere around it so get it filled and pressure checked. They wouldn't be heater or a/c lines.
