2001 Tahoe running cold
Ok everyone new poster here. I'm having issues with a 2001 Tahoe I just purchased. Very clean vehicle with 175k miles on her but now that the weather is getting into the 20-30s every morning my Tahoe doesn't want to get to operating temperature. I already replaced the thermostat and that had no change in the running temperature. I drive 25 minutes to work each way and its usually 15 minutes of that trip is 75-80 mph in the interstate and it still doesn't get above 170-180 degrees

Welcome to the forum.
What temp. t-stat did you put in? I read once that they are only good for +/-20%. |
A 185 t-stat. But the engine isn't getting hot enough for it to open. After I drive it the bottom hose is still cool like the thermostat hasn't opened yet

No thermostat isn't in backwards. The one for this Tahoe is a housing with the thermostat made into it.
|
Put it in a pan of water w/ a thermometer in it and raise the temp. of the water 'til it opens. I'm betting on a faulty t-stat. Not that unusual.

Thermostat isn't really the problem. I can drive for 20 and the engine not get to 175. So even if it was stuck open it may be a different problem that I'm not familiar with
|
Put a piece of cardboard in front of the radiator, covering 1/3 or so, see if the engine temp gets up.
