Water Leak

I have about 500 miles since the conversion and have had a water leak that I haven't found- its existed since the first drive. Its not bad but seems to be getting a little worse. All the normal checks for clamps, hoses, radiator has resulted in nothing. I've had it on a lift and see nothing other than, it seems to be coming from the front of the engine. I have not taken the belly pan off but may try that. I'm suspicious of the pump but would like to verify before replacing it. The motor had 54k when removed from the donor but I have no idea how long it sat before I bought it. Any experience/ideas are welcome. Thanks

its real hard to diagnose a coolant leak over the internet. just tossing that out there.

the ls engines dont have many places for coolant to leak from. really it can only be the water pump, the steam pipe or the head gaskets. my money would be on something related to the water pump.

Thanks for the response, thats my guess too. I understand its hard to diagnose without seeing it! Heck I can't really do it looking at it (yet). I guess I was hoping for something like 'the pumps leak after sitting awhile' or 'look (fill in the blank)". I can see that its not the steam pipes or anything high on the engine. I saw a drip on the alternator but not where it came from. Since its not a big leak (maybe 3 or 4 oz per trip- every trip!) I assume I wont see anything that's clear as I start disassembly. So, I was just asking to see if this problem sounded like something that someone else had experienced and solved. Its cold now in Kansas and I wanted to drive instead of taking it apart again in freezing weather but I hate leaking antifreeze on the concrete for the cats to drink and I hate the idea that it will get worse in a hurry. thanks again!

if its been leaking for a while you will likely see a trail of dried coolant somewhere, especially if you run dexcool or any other long life coolant.

Whenever I get a tough one to trace I put a coolant pressure tester on it and pump it up so I can get it leaking at a decent rate and follow it to the source. Just a thought.

That's a good idea. I had one years ago and over a couple moves I no longer do, so I didn't think about that approach. Thanks for the suggestion.
