Those two hoses are probably the heater lines, that flow antifreeze to the heater core under the dashboard. One of those hoses most likely has a leak and needs to be replaced.
Usually if it's leaking at the firewall, it's a heater hose, or depending on what engine you have, a coolant pipe on the engine. With this age of vehicle, it's more likely that a heater hose has a leak, or the clamp has failed, or something similer. Most of the time, if the heater core fails, you will smell it on the inside of the car, and you will usually find your floormat and carpet getting wet.
White smoke means water/antifreeze entering the combustion chamber(s) or intake passages. Suspect a gasket leak somewhere (tighten all intake manifold nuts and bolts). Check all radiator and heater hoses for leakage and hose condition.
You are going to have to look carefully at everything and find where antifreeze is coming from. Could be that something was left a bit loose or that flushing opened up a weak spot on the radiator. This being said, it also could be spillage from service that has not been blown off yet... Watch your coolant level and temp gauge, or better yet, bring it back to who did service and have them go over it for you...checking leaks is an important part of the job...so is cleanup!
Try changing the fuel filter, water trapped in it can freeze. Its a 92 and probably time for a fuel pump. They don't like water either.(Meythonol Fuel) Always change fuel filter when adding antifreeze to fuel
your heater core has probably sprung a leak.does the smoke smell kinda
sweet?....check the floor in the front where the floor mats are for
moisture or even puddles of antifreeze.(the replacement of a heater
core can be very expensive as the entire dash usually needs to be
removed to access the heater core)also look under the engine near the
firewall for antifreeze drips.
