Found this on the side of I-840 today, Magnavox console tv.

Yeah, the snow is only an inconvenience at worst... It can be useful too. Folks at work are afraid to park in the half plowed spaces...I don't like(/worry about) my GMC much so I just run over the snow hills and park on them. Seems as soon as I do someone else will get the stones to park there after I leave for lunch.
The cold REALLY stinks! The heater in that GMC ain't worth a damn under 20 degrees...It barely can get the car above freezing once it hits zero...engine runs real cold too. If I had better winter clothes I'd try taping card board over the grille to see if impeding cooling helps.
Saw something unusual on the way to work today...I guess it would be called a 'snowbow' since it is WAY too cold for rain...Did not know such a thing could form in weather this cold.

Thermostat stuck open, perhaps?

Or missing.....had that on a Nissan Truck I troubleshot for a friend - A/C use would overheat the engine, so the dealership removed the thermostat. Come cold weather, he froze his hiney. Installed an OEM and no more problems, and gas mileage went up considerably......

My old volvo had that problem, the thermostat failed in the open position. worked great in the summer froze till i figured it out. oh i'm thinking the H.O.T transistor has failed I tested it with my Leader in circuit tester and and it said dead. I let the power stay on for about 30 seconds and the heat sink is warm. In findem keepem's post with the helpfull hints it said the trans is a 2sd1398(8)?

Thanks for the tip! I'll have to check into that. Symptoms match what I've read. Replacement thermostats claim 192 degrees F is the factory open point, if the temp gauge is accurate I'm not making 150 F in 30 min of operation...IIRC the check engine code I have was traced to timing and cooling system...Time to find that sheet, and order a new thermostat.
