Question about 1996 Chevrolet Impala SS
I have replaced waterpump, thormol stat, and my radiator on my impala 1996 model 5.7 what is the problem
On my 94 (106,000 miles) I did the same thing as you with an overheat problem. It came out of the blue one day driving. Had never had a problem before then wham steam everywhere.. Changed the radiator, waterpump, and thermostat and still had overheating. I backflushed everything and hand flushed the coolant tank to get every last bit of gunk out. Still a problem. Was thinking like the last comment - Cracked head. Well are you ready for the solution.... I neglected to check the radiator cap on the coolant tank. It was original to the car and I just didn't think about it. Changed it out for a new one and no more overheating.. It was obviously not holding the system under much pressure. Enough for a short drive but that's all. All that work for a $10.00 part. Makes perfect sense now as Impalas run hotter than a lot of other cars anyway. Need the pressure kept on the coolant to keep it in check.. Hope this helps... Jeff

Timing could be off. Or you could have a cracked head. This would cause air in the water and cause it to over heat.
