if you just replaced the water pump, i'm sure its just the spilled water still burning off. I hate I hate I hate coolant. It never seems to go away. If you're sure there is no leak then just wipe everything down again to be sure.

check for a vacuum leak like Bosko said.
i looked under the car theres coolant on the sway bar but nowhere else i raised the car up a tad to look under let it run for awhile but it didnt leek the wheep hole is dry but seems to be a small puddle just sitting above oil pan could that just be left from when i changed pump and for the vibration problem i looked at the harmonic balancer and the rubber seems to be half way out so could that be the problem and if so do i get the 28oz or 50oz thanks for the help
And in the mean time don't drive the car. A spun balancer can do lots of internal damage if ignored.

If you are interested I have the complete 1995 FORD car CD service manual. EVTM (Electrical and Vacuum Troubleshooting Manuals), Service Manual and PCED (Powertrain Control/Emissions Diagnosis Manuals). PM me for details.
