Question about 2001 Chevrolet Impala
You have to verify if you have residue from coolant near the EGR below the composite air intake. If you are adding coolant and the car engine still have power then your coolant is vaporizing out and not in into the engine block. Otherwise if the coolant leaks into the engine block the car will act jerky since water is not compressible. Check the oil to see if it looks like coffee color (happens when water and oil mix).
No matter what be prepare to replace the lower/upper plenum gaskets, air intake and the tube that connects from the air intake to the EGR. New air intake comes without the tube. Replace to the lower plenum bolts. All parts available from www.rockauto.com
