Back to the drawing board. The mechanic says he pressured tested the coolant system, let the engine run for 45' and didn't find any leak. He then replaced the thermostat, pressure cap and bleeder valve, but the car is still loosing coolant. Today, I just drove two miles and left a trail of coolant (~ one gallon) on the road. The temperature was perfectly normal. The coolant drips profusely from the bottom, next to the rear right axle. I checked the overflow plastic bottle and connections. There's a little bit of coolant there, but there's no way one gallon would have gone thru the cap.

The mechanic suspects a head gasket leak. Is there any way for the coolant to escape in that area, other than the pressure cap?

Again, your experience and advice would be welcome.
