in need of help

[IceMan]

well i have a 1986 rx7 n/a. and i just the other day replaced the plugs, radiator, and cleaned all air intake stuff. and wheni finished i started it and it seems to be blowing a little steam or white smoke out of the exhaust and its leaking coolant out of somewhere above the exhaust manifold but below the intake i think. any ideas. i dont want to tear the motor down if it turns out to be something simple

Ck and see if hose goes into a firewall (passenger side) is OK.
