2002 Lincoln LS V6 overheating, please help
I have a 2002 Lincoln LS V6 that has recently started overheating. I recently moved to a new city that is much hotter then where I used to live, but it was fine for about 2 months here before it started happening.
I topped off the coolant in the resevoir and did a cold start this morning. Turned the heat on full blast, and let it idle for about 30 minutes.. Fans on, thermostat opened at operating temp, and it stayed at dead center on the temp gauge the whole time. Turned the heat off and let it idle for another 15 minutes, still didn't overheat. Got in and held the RPM's at ~2K, and within about 2 minutes the temp gauge was at 3/4. I shut it off and looked under the hood, and there was a steady stream of coolant (stream about the size of if you were taking a piss) leaking out from somewhere directly under the resevoir on the driver's side. Stopped leaking after about 3-4 minutes, and there was a slow steady hiss for a couple more minutes.
Any clues? Is there a drain hose in that resevoir somewhere that would drain the coolant out if it started boiling over? Or do I have a crack somewhere? Its weird that it didn't start leaking at all until it was overheating.
Any help welcome, thanks

A cracked degas bottle (what you are calling your reservoir) is a common problem. The degas bottle is under pressure and the plastic can crack. Like all those plastic bottles they crack and leak. Attached are the procedures to replace your degas bottle.

Thanks, I figured that out about an hour ago. I have since been working on getting my old degas bottle out so I can inspect it - however, the first bolt on my firewall brace i tried to remove broke immediately and the rest feel like they are about to do the same. I am not sure if I will be able to get the degas out/in without removing it.. I am nervous about forcing them - only 1 actually started turning without a ton of leverage on my end.
Any tips? Can I drive without my firewall brace if most of the bolts end up breaking or is that a crucial structural component? Or is it possible to replace the degas without moving the brace, albeit a bigger pain in the ass?
Edit: Ok, I got another bolt to give. At this point I have 1 bolt loose on each side, and one of the middle bolt holes is empty so I could theoretically just get another bolt and have 1 on each side, 1 on top. That enough to be struturally integrid? The rest are almost definitely going to break when I try to take them out.

Usually applying greater torque to undo a corroded bolt results in the bolt breaking. Apply a little penetrating oil to all the bolts, and the area around the bolts and leave for a while. You need to tighten and loosen successively while applying a little more penetrating oil. The oil will seep in through tight fitting parts and dissolve the rust. You have to be very patient and keep working the bolt. The brace is for the suspension towers and usually required for high speed cornering precision where it keeps the towers from distorting under high loading. Drive steadily and you will not notice any difference from a missing brace.
The broken bolts usually need to be drilled out, to a diameter less than the nut threads since that location has a high corrosion factor.
