This is a 1995 honda civic lx, everything under the hood is "stock" as in no mods only replace parts as they go out, and there is no a/c.
I was driving a few weeks back and felt like the car was "hot" but the gauge inside was only maybe 40%. I pulled over had nothing in the reservoir, filled it, let the car cool saw there was nothing in the radiator, so I filled that. Took it home, ran it with cardboard to find the leak didn't see anything. I replaced the radiator cap, and drove it around about 10-15 miles, and parked it with cardboard. I saw a green coolant leak coming around the oil pan and the muffler line(?) It was syrupy and only produced a 2-3 inch spot on the board.
Fast forward to today, its been sitting while I figure out my next move, drove it around the same distance as before and parked with cardboard. I noticed immediately a stream of coolant coming from under the car, popped the hood and saw it was coming from the top of the reservoir, it was totally overflowing. I have not checked the radiator again, because it was hot.
There is not any steam/smoke/liquid in tailpipe.
The radiator was replaced in 2010.
I had my oil changed 2k ago at honda, and only problem was rear brakes, which were replaced.
This car has not had mechanical problems since I got it in 2008, I don't even know where to go diagnostically from here, any and all help is appreciated.
