Coolant leak and high idle temp.

[DannyO]

Hey guys-
First off, I'm a newbie poster but a long time reader. Good to join the fold! On to the fun stuff....

Over the last month I've noticed leaking coolant. It started out leaking so much that the reservoir would be dry after short trips. I tightened up all the hoses that I could get at and the lately the leaking has slowed up to about a 1/4 gallon per week. I think I've spotted a small trickle from around the water pump. Engine temp runs normal while driving but begins to creep up at an idle.

So... any ideas at what I'm looking at? Leaky water pump? Bad thermostat? Thanks in advance for the help. I'm fairly certain you guys know everything....
