I have had coolant leakage in my 1997 cheverolet blazer and have talked to people at different dealers to no avail no one recommended that I have a systems check now I find out there is a technical bulletin that I stumbled upon at jasper engines that shows that the 1992 through 1997 gm 4.3l VIN r&w engines have the problem that coolant loss has been associated with cracks that may develop in the lifter valley area of the block. Until I came upon this nobody could give me a answer is there any thing that can be done to help me resolve this issue.
