Seven problems related to manifold/header/muffler/tail pipe have been reported for the 1996 Chevrolet Suburban. The most recently reported issues are listed below.
1996 Chevrolet Suburban developed problems with the brakes, intake manifold, engine cooling, transmission, tires, fuel injectors, fuel consumption and wipers. Consumer stated that the dealer did not do anything but take the battery cable off to reset the computer and the brakes were never looked at.
I have owned 2 1996-1997 Chevrolet Suburban and have had the intake manifold leak on both at about 85000 miles. I did a little local research and found that this is a very common problem for the vortec 5. 7 engine. When I called the dealership about a coolant leak from the engine area, the service writer said this was most likely the intake manifold because they get that all the time. 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. It costs approximately $500. 00 to have this done. I now must make the decission to have it fixed at the dealer for $500 or to do it myself for about $150. 00 and a day of headaches.
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.
