Stop driving the car
Check the water pump and hoses
you can get a look at it by pulling the carpet behind the seats and removing the access panel

probably not the head gasket

if its the water pump. its a reasonably easy DIY

Water pump, Thermostat, and coolant will cost you $350-400

Or you can have an indy shop do it, probubly add $300-400

What part of San Diego are you in? There are a lot of good shops that will not rip you off here

That is certainly good advice. Both the water pump and the rear overflow hose dump water by the right rear tire. So, the pump could be leaking, or the car is getting really hot and the pressure is causing the coolant to dump out of the overflow. When I rebuilt my engine I had coolant blow out the rear overflow after initially filling it with coolant. That was likely due to air in the system. Has the coolant been changed or drained and replaced recently? Is the coolant green or pink?

So you likely have "coolant pudding" instead of coolant. The car uses pink coolant from the factory. Dumping in green prestone causes a chemical reaction that thickens the coolant making it unable to efficiently cool the car.

That's not completely correct. There has also been green factory coolant. Porsche has also used yellow. The current color is pink

I just changed my WP and coolant and what came out was green and it was factory coolant

And my 2003 was pink. No idea if it was factory though as I was not the original owner. So, do you know how to determine if it is coolant intermix?
