so i live in east pa and the past couple of weeks we have had some cold weather. and recently i have been noticing some wet spot under my jeep. so i pull it in the garage and climb under and it isnt any kind of oil. kinda looks like antifreeze, but not to sure. i have noticed when i squeeze the bottom pipe for the radiator it seems there is some hard stuff in there, not like the top as everything seems to be flowing right......could it be possible that my bottom pipe is frozen and pushing coolent out where i can? now about 2 years or less ago i have the water pump replaced so i hope that isnt the problem again.. does anyone have any ideas on the pipe? is there anything in the bottom pipe to make it more solid then the top? thanks
