Chevrolet: 1994 Cavalier front (left?) rattling/stalling in drive, coolant leak, coolent

Question
Hi There,
  My '94 manual cavalier has been rattling from the front, getting progressively worse.  I have also had a coolant leak for a while, also getting worse, but I haven't noticed any ground stains.  I put in stop-leak 2-3 times already.  Today the car stalled while driving about 25km/hr...after that the engine would start, but it would stll when put into reverse or drive.  After 3 minutes I tried again and was able to drive 1/2 block to my destination.  Any ideas?

Devon;
  I wonder if the water pump is going on you. if you put in stop leak and it did not help you than you have a leak someplace - and it must be fixed. that might be why it stalls due to being to hot / over heatig or even the wires or engine might be getting a bit wet. You should take a pressure
test on the rad. to see where the leak is comming from.
and check all hoses and clamps and the rad. cap also. you are loosing coolent from some place.  ok
