That is a coolant recovery tank not an excess water bottle. You either have air trapped in the cooling system because you failed to purge the air correctly or you have a leaking engine head gasket.

The sweet smell sounds like the converter stoppng up. But don't think this could cause it to boil in the resavore. Also might take to a shop just to check the hose may be colapaing. good luck sorry not more info.

I borrowed a friends car (2002 Thunderbird). The coolant gauge spikes from acceptable range up to hot "H", red light comes on for about 20 sec and then turns off and gauge goes back to normal. ...

What you are describing sounds like there is air in the cooling system-Start the engine when it is cold with the cap off of the overflow and turn the heater up to full blast-make sure there is coolant in the reservoir, and keep an eye on the gauge, At the point where the thermostat opens, the level in the overflow should drop-top off the overflow filling to the 'full hot' mark on the side of the tank. Put the cap back on and drive it, watching the gauge. If you still have issues, you may have a problem with a malfunctioning thermostat. If it is alright after doing this, make it a point to check the level when it is cold again later to be sure the coolant tank is up to the 'fill cold' line.

I have a 1992 cadillac deville.i have a problem with the water going from radiator to the water reservior after it driven for awhile.what could the problem be?

This is normall oppertion, as the coolant heats up it expands just like water in a pot on the stove will boil over, hence the reson for the tank to catch it and return it to the radiator as it cools down. Now, if your coolant is not being returned to the radiator when it cools down you will most likely need a new rad cap.

Water was boiling and spraying from overflow / reservoir tank from what appears to be a factory made hole. was there a plug in there that might have rotted off and caused this?

well that mean that oone your thermostat is not opening or your water pump or possible that a hose might be collapsing to cause the water not to flow

Light on dashbord for a 93 gramdam looks like a radiator with a arrow pointing down i put fluid in it but it doesnt go off

This is a coolant level warning light,and lets you know when the colant level is low,If you added fluid to the radiator and the coolant reservior and the light on then there is a fault with the senor its self.
the sensor will be located ether on the coolant reservior or the side of the radiator.
Check the side of the reservior to se if there is a sensor with some wires going to it,if so try unpluging the sensor and see if the light gos out,If its not there it will be on the end of one side of the radiator tank,it will be a 2inch square box with some wires going to it,Fallow the same thing- unplug wires and see if light gos out.
If the light gos out you will need to replace the sensor,or just leave unpluged and keep a watch on the coolant level.

What you need to do is to check where the leak is coming from. If you have to add water after it's run, then i suggest maybe putting a cardboard under the engine after driving to trace if there are any leaks. Also check the coolant/water level when the engine is running at normal operating temperature, both the radiator and the reservior. But please be carefull when you do this due to pressure, specially when checking a radiator in the condition the cooling system is in. And last i would suggest putting distilled water rather than regular tap water. The water from the tap is hard water so it will have the tendency to evaporate a lot more quickly than soft water. Hope you fix it.
