The coolant crossover pipe started leaking serious antifreeze. I had it repaired in November of 2013 just to have it start leaking again a few months later. I need to have it repaired again but mechanic told me it was possible a flaw in the metal design from the manufacture not allowing the pipe to seal properly. I have contacted Saturn twice, once last year and then again a few weeks ago and they won't admit fault. I have done some research on this and it was a serious problem with the gm 3. 5 motors on buicks, chevys, pontiacs and others to numerous to list. They were aware of this problem and only put out a service bullitin. My most recent estimated is 1110. 00 and last year I paid 430. This needs to be stopped from gm getting away with this.
