Just read about all the expense and problems being caused by GMs dex cool coolant . I also am starting to develop leaks in my s10 pickup due to this defective product. GM recommends this product in their vehicles and GM should be held responsible for either recalling this junk and for any and all repairs caused by it. Its no wonder that people are switching to foreign cars They are built better and have far fewer problems . If GM fails to rectify this problem it will lose many more customers I personally will never buy American again if they to take care of my problem.
