What are the symptoms of losing a freeze plug?? I'm leaking coolant, even when the motor's off. I have a feeling this is it, any other possibilities are greatly appreciated. /forums/images/graemlins/1zhelp.gif It's dumping from somewhere behind the motor.... I'm gonna clean the oil off the motor so I can see better... as well as check a few other things /forums/images/graemlins/crazy.gif UPDATE Just took a look at it, doesn't appear to be leaking into the crankcase or cylinders. Verified this by the oil diptick having no evidence of water.... And I think that when coolant gets into the cylinders it results in white smoke, which I don't have. Anyhow, it is leaking, and bad. I still think it's a freeze plug at the rear of the block but I can't see back there. Coolant is leaking from the deal right behind the crankcase and before the tcase when viewing from below (out of a little hole)... It leaks with the engine on, and off. This is really frustrating and I'm hoping I didn't crack the block. Any input is appreciated!
