One more excellent DIY with pictures in this link.

Outstanding! Thanks for the info. I wasn't too sure where I should be looking for coolant leaks. I picked up a pressure tester from Harborfreight this afternoon. I figure the $70 I spent on it after the coupon is worth 30 minutes of a mechanics-time, so worth the investment for sure.
