update. tried to trace leak, appears to have condensation on trunk lid and coolant around cap area. also leak seems to run down side. maybe leak higher up on tank? maybe thats why it seems to stop at the minimum? thanks for your thoughts

Had a similar problem with my car the first time it went on track, it was the tank leaking down to the wheelwell. And it only leaked when it was hot, tank expanded some and exposed the crack which I could never see until it was out of the car. Plan on an entire afternoon to change it out. Was not fun.

You need a new tank, period.

yes your prob right Jeff.

i pulled carpet and took a 45 min drive. not a drip. ! im thinking i overfilled it? but its at minimum. when i topped it off it seemed to expand . but after a good drive, not a drip. i have a feeling if i top off the coolant, it ll leak again.

before i kept coolant level right at max. and it never was a problem. now it seems the reservoir tank likes to be at the min. any thoughts?

If you have coolant outside of the tank, then you have a leak. It just that simple and the cause is either a broken tank, cap or connecting hose. Eventually, you will lose enough coolant that your engine will overheat. If it does overheat, you may face thousands of dollars in resulting engine damage.
