Hey guys,

So I already had a minor leak chocked up to the EGR cooler that I was going to replace anyway.

However last Friday (20th of July) I had a very minor fender bender where I rear ended someone. Arguably, the only known damage to my car was cosmetic (my bumper). However yesterday after I arrived at the local Target in the afternoon, I noticed a strong hissing sound (like my tire was punctured). I opened up my bonnet and saw that the sound seemed to be coming from the back of the engine. I've included a video that I took (just ignore the baby sounds as I was in the parking lot):

When I arrived back home (my house is on a hill). I noticed a trail of coolant while I was driving slowly up the hill. My Mother then decided to point out to me that she noticed a small puddle of coolant in our garage before we left on our shopping trip.

I thought it might have been low coolant - so I topped it off (with distilled water).

I later went on a drive last night in Boston for about 10 miles or so. This is the first time I've seen my car overheat. The gauge was basically halfway between 190F and the redline, sometimes it seemed a little closer to the redline. I immediately drove back home. I listened to the engine bay and the hissing was still there albeit MUCH less pronounced.

For the record my car is pretty much running 100% distilled water temporarily and I've had no problem with the temperature going above 190F before. All that used to happen is the car would warm up pretty quickly. I've only been running this mixture for a few months while I saved up to fix everything on my car (I'm a poor student). I have 145K miles on it.

The thing is I have work on Thursday (I'm a delivery driver) and I need to get this fixed ASAP. I should be able to fix this myself as I am an aerospace engineer and naturally mechanically inclined.

Also I saw this wire touching the engine in the rear. Is it normal to be in this position?
