Hi everyone! Opened the hood today and noticed there was no antifreeze in the reserve tank or under the radiator cap. Filled it up and started the van (2001 Express). After a few minutes I looked underneath and saw a small drip coming from a very odd location.

It is dripping right behind the lowest pully in the serpentine belt pretty much directly over the front axel. It looks like it is coming from (oddly enough) a seal that is between the pully attachment and the front of what I would assume to be the oil pan. I can feel wetness all around the seal, but I can't feel any above it nor see any visible leaks. It is most defintently antifreeze and not oil. Any ideas? Thanks!

 

Do a taste test, antifreeze is sweet and oil is just nasty plus if you haven't changed it might smell bad to. Would be hard for to say what the problem is without a picture I'm trying to picture the lowest pulley i keep thinking about my water pump issues.

 

Lol, thats the best one yet today.

 

Thanks for the replies. I took it to a local shop the same day and they did a pressure test on the system. Turns out it was leaking at the water pump and at the intake manifold. Had to replace both for a cool $1,800...ouch.
