Coolant leak on Driver Side Block

The "Low Coolant" message came on today so I added additional coolant and didn't really pay much attention since I've found no coolant on garage floor ever. Well now that I'm on a trip, I noticed about a 1 1/2" puddle of coolant on the driver side on the ground. Upon inspection, I found a small amount of coolant dripping down on driver side about in the middle of the block. Cannot find source of leak due to hoses, etc. Anybody got any ideas on where to start my search. The truck has 95K miles on it with no other mechanical issues. Thanks for any input.

Your water pump needs replaced. It is leaking from the weep hole.

It is a good idea to replace the pump housing as well when you replace the pump.

Thanks for your replies. Is there a way to view the "weep hole" to confirm it's the water pump on the Chevy?

You can use a small mirror to get up in there and look. If you have a good light you can barely see it without a mirror. You have to remove the plastic lower engine cover to see it.

After getting some time to look for the leak it appears the motor is wettest around the thermostat housing behind the alternator. It is difficult to pinpoint due to all the split loom, tubing etc in that area but does anyone have any idea what might be leaking the coolant. It is not much of a leak so it makes it that much more difficult to find. Thanks for ay ideas.

Auto Parts stores sell a kit for pressurizing your system with a bicycle pump. They are cheap - under $30 if I remember. You might want to pick one up to help you find the spot. Just don't go crazy - 14lbs should be enough pressure.

Thanks Tom and what I did was go to the local O'Reilly's Auto Parts and rented a kit to pressurize the cooling system and found a leaky hose behind the thermostat housing. Cost less than $8.00 to repair the leak. Thanks for your assistance.
