Ok folks, here it is.

I have a coolant leak. It's slow, apparently. A few months back, I filled up the coolant reservoir. Yesterday, the check engine light came on and the reservoir was empty. The car doesn't leave any drippity drops so I figure the radioator is probably not cracked. I suspect it's the hoses (did not replace when I bought the car early summer of '06).

So my question is, what do I do? What should I check for when I get home? Should I go down to my local Kragen and tell them I need to replace all my coolant hoses? And then will they be able to tell me which hoses I need and buy?

Thanks folks!

Do a pressure test. If you have a friend with the tool, borrow it. If not, buy one. Pump it up to like 20 lbs. and let it sit. Measure the length of time and how much the pressure drops. Then check every where for wetness.

I believe its called a cooling system pressure tester.

Check around where hoses connect to nipples. Check for loose hose clamps and look for cracks. Hoses usually break down and leak from the ends first. Don't forget to check the small coolant hoses too.

Endless got the name right.

And they look like this:

And as Endless said check the clamps. Stock spring type clamps can lose tention over time. Sometimes enough to let coolant/water by under pressure.
