I went out to check on the oil, everything good, but I notice the coolant resevoir is nearly empty. It was full not even a week ago. Not good.

Everything looks dry, clean, no o-ring leaks... Oil dipstick looks fine, no foam on the oil cap either.

Under the car I notice this:

I'm thinking something is leaking from this location. One of the clamps or the bleeder. Any ideas?

Looks like the heatercore maybe sprung a leak?

oh no! wouldn't that leak into the cabin?

I can't tell if that coolant is dried up or what. It might be from when someone was burping the system through that blead screw. Either way, now that I think about it, i'm not sure the coolant would exit under the car there if it was leaking that bad. Maybe it's coming from another place behind the engine. We need more pics...

it leaks out in that area by the cats.

hard to tell where you have a leak.

and none of the hoses are leaking then it looks like you will be performing an R&amp;R on the heatercore soon;-(

tightened clamps and cleaned it up. I'll see what happens.

Im sure you've never used that bleeder anyway.
