If that SE has the Duratec 2.5 V6, you could very well just need a (metal impeller) waterpump, maybe a thermostat and a temp gauge sender. Try to get the pieces of the old black plastic impeller out. Make sure the cooling fans run at the M on normal (temp gauge).If the previous owner overheated the engine a lot it might need head gaskets, although it seems to me few are changed unless modifying the motor.. Those parts solved that problem on a 98 Mystique LS I got last year for cheap. Good luck fixing up the SE.
