I have a coolant leak and not sure where it is coming from all I see it leaking from right in front of the trans. pan I looked from the top of the engine but can't tell where exactly its from. I flushed my system about 3 mos ago had a brown sludge in the neck on the rad cap and in the resivor. noticed the leak started about a month ago. I was told by someone that it might be a freeze plug. Does anyone have any ideas?
