Leaking coolant problem

I decided to remove and replace my horrible looking motor mounts. I jacked up the engine from the oil pan with some wood blocks to distribute the weight and all. At some point I must of loosened up or broke something in the coolant system. Now when the truck is sitting I have a slow leak of coolant. It doesn't appear to be coming from the radiator or the the fill cap. When the truck runs for a while and the engine heats up I see coolant leaking like a faucet. I just can't localize where it's coming from.

Any ideas what to look for?

How old are your coolant lines? You may just want to wholesale replace them if they're more than four or five years old. You may also want to check the coolant reservoir.

Coolant lines are 3 years or a little older. I looked at the reservoir and didn't see any leaks. I'll have to order some new lines and see if that corrects the problem.

Some places can also do leak testing using a dye and lamp setup that causes the fresh leak to glow.

You probably loosened the lower radiator hose / clamp while jacking the engine up. I did the exact same thing, visually inspect, adjust hose/clamp and you should be ok. That or put a new hose on just to be sure.

I'll check the coolant hose in the morning. If that's not it I'll look for some place that can do a leak test.
Thanks for all the suggestions.

You both had it right. The one of the coolant lines looks a bit older then the rest. Must have not been changed out when I had work done on it. The line looks a bit worn and the hose clamps on a few were loose. But I did find the one responsible for the leak! Tightened down and I'll be ordering a fresh set of coolant lines and clamps so they all are in good working order.
Thanks for the help and diagnosis!
