    Looking under my hood today I noticed the reservoir looked kinda dark. I decided to dump it into a separate clear container to inspect it a little further. So it still has a green tint, but just looks dirty. I did notice that the very top is still bright green, so I'm hoping to put my fear of oil to bed. Radiator is fairly new, put on in the last 2 years, tops. Car hasn't been driven for about 2 months. My guess is that it's rust from the system. I just wanted a little confirmation before I flush the system and start driving it regularly again.

    Sounds like rust. Had that problem with my Camaro after it sat a while. Flushed it thoroughly and it was good.

    My guess is rust as well. Anything could have settled in your plumbing causing a little buildup. Should be fine with a flush.

    I should mention, I parked it because it was getting hot at idle last time I drove it. Today I was actually trying to diagnose that issue. Of course it didn't get hot, rad hoses heated up nicely, and the fan kicked on.

    I'm with B. start with the easiest fix. also, make sure you didn't have shitty water leak into your reservoir.

    I think I'm going to flush it, and while its empty, replace the thermostat.

    Reservoir is good. I actually pulled it out to check if it was related to a problem there.
