After I have cleaned it up the best I can. Someone else suggested it might be the right front corner of the intake leaking. When I checked there was a small puddle of antifreeze on in a casting groove on top of what I think should be the water pump. So I cleaned everthing up as best as I could and put the truck outside to warm up. After 15 minutes no signs of any leaks.

I took it for a short drive, and still no signs of anything. So it is now parked back in the garage, and after 3 hours no sign of a leak.

Two things I am wondering about.

1) Maybe it is the upper rad hose leaking when it is left outside in temps below -30 and it takes a while to work its way down.

2) Right now I have the truck up on ramps in the garage and maybe this has something to do with it.

Thanks to all and I'm still looking for the answer!
