Sube

I purchased a 1997 Legacy Outback LTD about a month ago with 158k and drive it everywhere. It runs like a new one (2.5) automatic. The previous owner said he had to add appx a quart of water every 100 miles to the coolant jug. Like I said, I drove the car everywhere, after examining it for external leaks and nothing until 2 days ago. The temp gage usually sits right below 1/2 way but I noticed it climbing so I shut the car off and coasted. After it cooled a bit, I popped the cap and sure enough, it was about 1/2 gallon low on H2o, so I topped it off. I got the car back home, from appx 30 miles away (70-80 mph) and it ran fine. I popped the cap yesterday and it was low appx a quart again. I topped it off, ran it for an hour or so and nothing. There were no external leaks, no water in the oil, and nothing coming from the exhaust other than carbon minoxide, that I could tell. I figured probably a thermostat or poss water pump. It was getting time for the timing belt to be replaced, so I did so. While I had it apart, I replaced the water pump, thermostat, bypass hose, and the cams/crank seals and the timing belt. I put the car back together, fired it up, topped of the radiator, let it run for for 1.5 hours and it ran fine. Got in it to drive, revved up the engine to appx 2800 rpm, and the temp started to climb again. It didn't go all the way to hot but stopped at around 3/4 of the way up. I felt the top radiator hose and it felt hot and like it was about to pop. I popped the reservor cap (no pressure) and the water in it was cold. I eased off the radiator cap and bubbles flowed to the reservoir and the pressure dropped from the hose. I'm thinking at this point, probably a clogged radiator (everything else external is new). After reading the blogs here, I'm starting to wonder. Should I replace the radiator, cap, or both and try again? The radiator is locally $229 so I'd like some advice before spending that kind of money for nothing. BTW-I also changed the plugs, plug wires, valve cover gaskets, fuel filter, transmission filter and fluid, engine oil filter/fluid, and both front cv joints right after I got the car. The car runs too good to be what experience I've had with blown head gaskets, so help me. It appears to only run hotter than normal when the fluid gets a quart or more low. Most auto's I've experienced with, that's not the case unless they're way low on coolant. Send me some experience, if you would. Thanks.

Pump rebuild kit.

Anybody know where I can find a power steering pump rebuild kit for a 1997 Legacy Outback?
