I have a 1996 Mazda B4000 4.0L V6 that is leaking antifreeze from the rear of the engine and dripping down where the transmission and motor meet. I have read some post on this site and it sounds like it may be a freeze plug. I had a slow leak for a few months now and could never find it I would have to add a little to the reservoir every week and a half or so, but all of a sudden in this crappy weather it all leaked out on the highway and I had the truck towed home. I will get a better look during the daylight tomorrow but if it is just the freeze plug how likely am I going to be able to replace it in my driveway with the engine still in the truck? Does anyone have any tricks or ideas about reaching the back of the engine?
