Is the coolant actually bubbling? Or just steaming? Steaming is normal, bubbling can indicate a problems. Does the car noticeably increase in temp as you accelerate? Cool off when coasting? If it does these things you may have an exhaust leak into your water jacket, a very bad thing. Exhaust gases will react with your water/coolant mix and make and acid, I forget which, but a very bad thing for aluminum.

Answer , the car cools as you drive it, but after filling the coolant reservoir to the proper level. No bubbling. Temp guage in the middle to a little higher. Normal and when parked there is no leak at all. Seems ok, thanks.
