Coolant leak
 

I have a 05 lly that has a coolant leak that I can't find. About 2 quarts a day. I replaced the seals on an injector that was leaking coolant and that seemed to help . Any ideas

florisent dye. might be a good idea. or mop up all the coolent you can, and then just watch under the truck to see where it is coming from. also i got this leak stop crap at walmart, just throw it in with you coolant, it works but i promise it isnt a long term fix. but it did stop the leak i'm haveing for now, just so i dont have to pull the water pump to replace a 5 dollar gasket.
