It looks like the plasiic petcock is bad. It's on the bottom of radiator by the bottom hose.

If it's a hose, you only need look under the motor while it's running. If you see coolant dripping or pouring out, it's most likely a hose or radiator leak. If you don't see coolant, check your exhaust pipe, if you see lots?of water, you have an engine leak. Pop the radiator cap, when coolant. Is oil floating on top. If so, you have an engine leak. Coolant issues are pretty straight forward to diagnose. Good luck, I hope it's a hose or radiator leak which is infinitely easier to remedy than an engine leak.

The chain is fine. I had it checked before. I'm hoping it's a hose that's leaking. It might be the original hoses from 87.The oil is fine and it only has 55K miles so I think the head gasket is fine. It idles nicely and I only drove it maybe 6 miles altogether. Thanks for your response.

Another possibility (if you're super unlucky and/or neglectful) is the timing chain on the 22RE
engine will stretch, rattle, and chew threw the front of the block into the water jacket.
?
Usually this catastrophic failure occurs at very high miles (150k+) and only after the
owner has spent months ignoring the horrible noise the chain makes as it slaps around
inside the timing cover.
?
Otherwise, start with the basics. Have a mechanic pressure-test the system and see where the
coolant comes out. If there are no visible leaks, then something like a blown head gasket is
the most likely scenario.

Good luck,
