One problem related to coolant leaking has been reported for the 1997 Chevrolet Blazer. The most recently reported issues are listed below.
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.
