Well one might say i was a skiing machine, in those 4 years more than 400 days of skiing, the ski patrol and lift operators went to the mountain less than I did. When I went to work it was delivering pizza or driving around, after all it was a Subaru.

Yeah, replaced the T-stat last week and the issue is officially closed, no more running hot. Thanks to all those that replied so promptly.

Dead-Last T-stat is out when I get home from work in the AM, well I will let it cool down first. How convenient one dealership in town is 6 blocks from work, the other 1 mile from home. Good to know I was headed in the right direction, I kept thinking to myself they look so different, and double and even triple checked the part numbers online to make sure before I installed it. Thanks for helping out. BTW Still running strong at 350K+ miles. Next goal 500K

1991 Legacy AWD Automatic About 1000 miles ago I noticed the tell-tale coolant drip from the Water pump weep hole. Before the recent battle under the hood the temp gauge never went above 3 o'clock, didn't matter if the heat was on or off, driving up a hill, down a hill, high speed on freeway, or stop and go city traffic. I Lurked on this board looking for recommendations. I Ordered the T-Belt Water pump kit from Mizumoauto, t-stat, picked up new plugs and wires, new air filter, oil filter and oil, and the accessory belts. Jumped in changing the cam seals, crank seal, water pump, t-stat, T-belt, the idler pulleys, tensioner bearing, the plugs and wires, oil and filter, accessory belts, and burped and filled the cooling system. Drove around town short trips no issues, felt comfortable driving the 25 miles to work. After driving for about 15 miles all freeway with no traffic, I noticed the temp start rising above the normal 3 o'clock position. I flipped the heat to high and turned the fan on high, the temp returned back to normal position. Turn heat and fan off and temp starts rising again. The air blows like a blast furnace. Things I have checked: Coolant bottle when I get to work is slightly above the full mark. Coolant bottle when I get off 12 hours later is between the fill and full marks. Checked the Radiator and the level is full, squeezing the upper radiator hose doesn't produce any air bubbles. No oil residue inside coolant bottle. No latte colored oil. My understanding is since the heat works most likely not and air bubble trapped in a pressurized system. No oily residue or latte colored oil indicates no blown head gasket. My guess is faulty T-stat, but wanted to seek help/advise before I drain the system and put the old t-stat back in. I just replaced it due to convenience since I had it out and thought to save myself work later if it went bad. I searched and came up empty with similar issues, so any help would be appreciated.

Current - 1991 Legacy Sedan = 365497 miles my first car a 1984 Subaru GL Hatchback bought with 179000 miles sold it 4 years later with 469000 miles, for $50 more than I paid for it. I saw it still running down the freeway 5 years later, have to believe it hit the half million mark. That car owed me nothing.
