1996 Chevrolet Suburban Engine cooling Problems

“I have replaced the intake manifold gasket twice now for my 1996 Chevrolet Suburban. Both times it has cost me over $650.00. Both mechanics told me that they see these at least twice a week on the 5.7 engines. They knew exactly what was wrong. They actually laughed when I asked them if it was set up as a recall item for this engine.”

“I have owned 2 1996-1997 Chevrolet Suburban and have had the intake manifold leak on both at about 85000 miles.

Toay, I noticed a coolant puddle in my drive way and upon looking into it, my latest 1996 Suburban with a vortec 5.7 is leaking at the intake manifold. This is a costly problem to the consumer. …”

Sometimes it will restart by shifting to n and re-cycling ignition switch without having to stop or leave road. Sometimes, as is the present case, it will not restart. I have owned this vehicle since new. This has been an ongoing problem beginning at 80,000 mi. Manufacturer extended warranty to 120,000 miles, has continued beyond warranty period and is a source of safety concern. …”
