Question
  Josh I saw what you said to the other person who had a similar problem as I do, but.... I have leaks coming from 2 differnt places. one I believe is the upper hose that comes from the resiouvor that I feed  my coolant into the engine through.(The plastic contanier which i pour the coolant into) The second one seems to be coming from underneath betweem the fan belt area and whatever the first hose is connected too. I did the coolant test with the car running and thats what I found let me say though it dumps coolant at a rapid rate in a short amount of time within in a
night ill have a lake of coolant under my car.
Thank you  

Answer
Johnny,
 The 325e is a bullet proof car, I owned an '84 and it had 325k miles when the Odometer stopped working.  Anyhow, you will have to locate the source of the upper coolant leak (around the tank), and probably replace the hose.  The second leak (fan belt area) is probably the waterpump leaking.  It's not too bad of a job to replace, but if it hasn't been done in the last 100k miles then it's time for one anyways.  I would double check all the hoses again, making sure that none of them are leaking at the waterpump.  it would be a waste of time to remove the waterpump and replace all the seals only to find out that a hose was leaking at the pump it's self.  Try looking from the passenger's side with a flashlight/shoplight at the front of the block, you should be able to follow it all the way to the waterpump.  if you see it coming out of there, then you know where the leak is.  But like I said before, if a hose is cracked at the waterpump, then it will run down the waterpump, making the waterpump look like the problem.  If you can, take a towel and dry the waterpump, if the water pump is the problem, then it will stay dry, and water will run form underneath it.  if it's the hoses then it "should" run all over the front of the pump.  
   Hope this helps some, dont hesitate to respond with more questions.

Expertise

I can answer questions related to the BMW e30. These are the cars produced from 1984-1991 (1992 for convertable) in the United states. I am more fluent with the six cylinder models, although few things changed for the 4 cylinder cars. I know most of the problematic areas of these cars, and have found ways to fix them.

Experience

I have owned six different E30's over the last 10 years. I do all my own work, and know about ever nut and bolt on these cars.
