I don't think that stuff is too good for your car. I can picture it just
clogging up your radiator.

Sounds like it's leaking at or around the water pump.

I doubt it's the head gasket.

It could be leaking at the O-ring gasket behind the pump, or the bearings
themselves could be toast and leaking from there. If it's leaking like a
sieve tho', I would expect that it's the gasket. Could be damaged, or the
pump could just be loose. You never know.

Makes sense if you have a leak.

I think it's time to replace the timing belt and water pump and idler
pulley (if it has one?).
It's no big deal, as long as you're reasonably good with your hands. The
procedure is well documented in the archives, and many of us can help walk
you through it.
