I haven't drivin my truck for about a week now, so today I went and started it up to warm it up and just listen to it a little . It ran for about half an hour, so I shut it off and went inside. I went back out a while later and niticed a dozen or so drops of green (coolant or ac stuff?) on the sway bar. I ran it again to see if it would do it again, but I haven't noticed anything yet. Any ideas, I'm a little stumped. I looked for a leak but everything looks dry and I've never had a cooling issue.

 

You said you checked for leaks,but did you look closely at the weep hole on the water pump?

 

I had a leak that would only present itself while the engine cooled. It would not leak while hot, cold or while being pressure tested. I also had coolant leaking on my sway bar. Look under the T/stat housing and along the edge of the cylinder head where it sits on the engine block in this same area.

I replaced the head gasket and no more leak.

 

The Weep hole on the water pump? I've never seen anything out of this before, but the truck has never sat more than a couple of days till now. Should it actually "weep" or is just a term. Thanks Guys, hope its not the head gasket, that would mean studs and all the rest lol!

 

If you feel around behind the pulley for the water pump,(on your truck it should be on the bottom side of the pump) you will feel a small hole maybe 3/16" in diameter. It's called a weep hole. That is a hole that goes to the outside of the seal. If the water pump seal starts leaking it will be from there. In your owners manual you will find that they recommend that you check this hole for blockage every service interval.
