Engine noise
Recently, after I have been driving short distances in my 3000GT SL (as in, under 20 minutes on the road), when I am idling at a light or about to turn the car off, I can hear a very loud humming/whirring sound coming from the engine. I haven't inspected it yet, but it sounds like the fans.
I'm inquiring about this because, although I've heard this sound before, it's normally occurred when the car has been running for a rather long time. I also inquire about it because I have a coolant leak, and was wondering if perhaps that had something to do with it...I don't know. If this is a really, really newb question, apologies.
Thanks, regardless.

RE: Engine noise
Well, fan turned on after five minutes of idling, and my coolant leak is getting consistently worse.
The only hydraulic jack I have was one my dad bought for his old Geo Metro back in the day, so it's not big enough for me to get under the car, it doesn't go high enough. However, I've been able to determine that coolant is dripping down from above the oil filter. Any ideas where it might be specifically coming from?

RE: Engine noise
If it is leaking down from the driver side of the engine, there is a good chance it is coming from the waterpump.
The "whirring" noise you are hearing could be the waterpump, or the many idlers/tensioners on that side of the engine. Take a long screwdriver and put the tip of it at various points around your pulleys, (careful not to tangle it up in the belts) and put your ear to the handle, when you get close to the part making the noise, the sound will transmit through the screwdriver (think of it as a poor mans stethoscope.)
