Default Coolant leak "somewhere"

Hey folks. I'm in the process of tracking down a coolant leak somewhere around the lower radiator hose, heater hose, or something else on the passenger side middlish area. I'm pretty sure it isn't the water pump as I felt the area around it and couldn't find the leak. When it'* light out, I'm going to put the car up and find the bugger...

If someone has the 95 shop books and are available tomorrow, could you be so kind as to PM me your phone number so I can give you a buzz in case I need a hand? (We're talking around 10-12 EST)

Thanks guys

Plastic coolant elbow was not too long ago replaced with the metal one.. I think Boosty replaced it 24 hours after he bought the car from its previous owner....

Uhh.. what are "weep holes"?

Oh.. 10 cents sounds like a good price.

Heh.. Might as well flush the coolant while I'm here.

Default leak

Look at the front cover bolt just to the left of the lower hose attachment (L27). I thought it was a loose hose clamp, but the front cover bolt was loose. You can get you finger in there to check but I had to remove the motor mount to actually tighten the bolt.

When the pump starts to fail, it'll leak coolant out of one or both of these holes. Pretty pulley, eh?
