Re: coolant tank cracks
I had this happen on my 96 Sable. At the time I was young and dumb and didn't really understand the whole closed system with tanks. I tried to JB weld the crack which I thought worked but I was wrong. I ended up having to replace my motor because I melted two pistons. Oh and the car only had 65,000 miles on it. The other thing I found out was that on those with the Vulcan 3.0 they used the wrong type of coolent and I had one of my freeze plugs errode away. The dealer said there was some bypass kit for these systems but I never recieved my notice. Of course it was too late the damage was done.
