    Sounds like you have a big air bubble in the system, which wont let the coolant circulat right. Bleed the air out of the system.

    Well mine is a 92 so i have the newer system. But when im refilling the rad i squeeze the upper rad hose while filling it up to burp all the air out of it. Usually takes a while.

    Wish mine were a 92 , Yeh my system is the whacky setup. will try & figure out why it started smoking bad all of a sudden tomorrow.......it may be that TPS wire or whatever its called, that run down sorta close to the ehaust pipe & into the side of teh transmission........periodically that thing can lose connection & itr wont start,like once every 6 monts so i have to jiggle it,although doubt that would cause the smoking all of a sudden.

    What color is the smoke? blue, black or white?
    Blue=burning oil
    Black=unburnt fuel (running too rich)
    White=burning water (blown head gasket)

    A good trick for the renix is to remove the thermostat and drill a very small hole, 1/16" or so in the top of the thermostat. Put it back with the hole on the top. This lets the air escape.
