1999 GMC Suburban. Intake manifold gasket failed. This occurred after replacing the water pump which failed for the second time in less than a year. My mechanic says this is epidemic with the GM vehicles which use the dexcool antifreeze. My experience bears this out: My previous vehicle was a 1999 Chevy Suburban, which had the same problems. There should be a recall of all these vehicles!

1999 GMC Suburban intake manifold gasket failure on 5.7L engine resulting in leaking antifreeze, and expensive fix. Thousands of similar failures, there should be a (forced) recall based on magnuson-moss !

Intake manifold leaks due to a defect in the design/materials of the gasket. The material prematurly breaksdown causing leaking of the manifold.

Left rear intake manifold leak. On a 1999 vehicle with only 48,520 miles (light useage for mom and kids) this problem seems a bit premature. My brother who owns a 1998 GMC with about 60,000 miles had simular problem. The part must be defective as both problems are very simular in nature. Cost to fix $700 to $1,000. Thank you
