So I have at least one coolant leak coming from somewhere in my engine bay but due to the amount and the place where the fluid's ending up on the ground, I'm consulting the experts before going any further.
This first image was taken over the engine bay from the driver's side. The red arrow I put in is pointing to a dark area right in front of the thermostat. The area's dark because it's damp from leaked coolant and, if you look closely, you can see a little bit of green from fresh coolant in that pocket. I last flushed the radiator and replaced the thermostat a few months ago. The last time before that was maybe two years before. To be honest, I've seen trace amounts of fluid appear in this little pocket before, but since there's be no noticeable effect on my fluid levels overall, I never thought much of it.
This next picture is what I'm more concerned about. As you can see, I took this picture from the passenger side and the fluid is right under the middle of the car, slightly behind the engine.
I put my camera under the passenger side of the car pointing upward and took this next picture. You can see part of the exhaust is wet from coolant.
This is the first time I've seen this volume of fluid coming from this area of the car. I first noticed it yesterday after finishing washing my car. I moved the car and there it was, a small puddle about the size of the one pictured above. The last time the car had been driven at the time was about two hours before, so the engine was fairly cool when I noticed the puddle. I drove the car again for about ten minutes shortly after noticing the puddle to warm it up and see if I could notice anything. When I got back there was no obvious additional leaking. I checked a couple hours later and still there was nothing. It's been close to 24 hours since I last drove the car and the fluid that's there now is all that leaked over that time. In fact, when I took the pictures I could see very tiny drops falling periodically. In spite of this, the fluid levels in both the radiator and the resevoir are where they should be. So whatever kind of leak this is, it doesn't appear to be very large right now. I did smell a minor odor of coolant inside the car when I drove it last, but I also detected this in the engine bay, so I don't know if maybe the heat of the engine spread it around (since fluid has leaked onto the exhaust). I suspect maybe the heater core (which is original) but I don't know how to verify this. So does anyone have any thoughts? Thanks in advance.
Also, there's about 142,500 original miles on the engine (no headgasket failure) and it's a '94 Thunderbird.
