My ever faithful 91 legacy wagon took a good bit of damage on Christmas when the crank pulley came loose and smashed everything to bits, so now I have 2 broken Subies and 3 weeks to get one of them roadworthy for school.

I did the coolant hydrocarbon test on the SVX the other day to look for a bad head gasket,
and I got no signs of a problem. I changed the thermostat today. The old thermostat looked extremely different from the OEM part, so that may explain a bit.

I flushed the radiator while I was in there. The brown muck in the reservoir made me nervous, but everything that came out of the radiator was nice and green.

I started it up and it took around 15 minutes of idling to hit the 1/3 mark on the gauge, though It's 30F right now. Took it for a spin and found that the needle wasn't fluctuating like it was, so I just may have dodged the bullet.

Tomorrow, I'll redo the block test and then take it for a longer test drive.
