August 2002

Engine coolant leak at the intake manifold, or at the lower intake manifold to lower intake manifold gasket. This condition may result in a low engine coolant level or coolant pooling on manifold. Same problem as noted in TSB#03034(NHTSA id#10003430, july 01, 2003) this problem is present in my impala that has been well serviced every 5k miles and suddenly presented at 96k miles.

Reported at 96,400 miles, April 2006
