comment How can we measure the tilt of steering wheel in car without any special sensor for it?
Are you asking if you can access a tilt sensor on the steering wheel by accessing something from the engine computer? Or are you wondering if there's an easy way to see that it's tilted?

Just to make sure: that's 0-30 degrees Fahrenheit, right?

comment Engine suddenly died on uphill, then went back to life after a few tries
That light looks like an injector and the "low power, revs stayed down" sounds like a limp mode. How cold was it when this happened? Note for answerers: some google searching makes it sound like this is a possible fuel pump or injector problem (supporting the warning light as well).

comment What items are in the cooling system loop?
This is quite vague: water cooled or air cooled engines? Any particular make? Vehicles from this or the previous century?

comment “Irreparable” tire damage incurred due to road pothole
Leaking air => probably requires repair.... If there are visible symptoms (i.e., would show up in a picture), it would be great to have hear as a reference for future readers. "This is an example of pothole induced tire damage - could be fatal to your tire."

comment In the -20F temperatures last week my temperature gauge was stuck under the 1/4 mark. Heating was also affected
It's not clear what you're asking. One way of reading this is "when it was cold outside, my heater had trouble keeping up." Is there are more complex problem here? Please provide more information so that we can provide substantive help.

comment “Irreparable” tire damage incurred due to road pothole
A picture of the tire and the damage in question would help us give critical feedback on the initial diagnosis.

... or did the coolant freeze in one of the lines?

comment Is it efficient to use the cabin heat in my car?
I agree - it will make a difference but it will be so small that it will be lost in the noise of everyday driving. It's an entirely different situation than using the air conditioner.

comment Assuming identical and sufficient ABS, and ignoring aerodynamics, are tires the only factor for braking distance?
@mac, I agree with your Milliken and Milliken reference. Rereading the Physics of Racing is unsatisfying: it's too casual and insufficient to fully model reality (e.g., you can't assume a constant frictional force because it is not constant). I've removed the link to POR and replaced it with Milliken and Milliken.

comment Low coolant in freezing weather
You might also want to add links to the related answers: mechanics.stackexchange.com/a/3575/57 and mechanics.stackexchange.com/a/5505/57 Straight water is a bad idea and your comment on freeze plugs in another good point as to why it's bad and how you can tell.

comment Does the amount of fuel in the tank matter?
@corsiKlauseHoHoHo, if you'd like to have a open-ended discussion about the physics about the multivariable system that is a car, please do that in the chat room.

comment How do I loosen stuck lug nuts in order to change a tire?
Just for clarity, you're only using the jack to balance the wrench, right? It's not carrying any weight?

comment what is difference between DOHC and SOHC?
Defining "volumetric efficiency" and the context in which the term is important would be improve this answer for novice readers (and the OP is clearly asking a novice question).

comment What is supposed to happen when my Subaru's test mode connector is hooked up?
@JoshCaswell, see jzd's answer below. All the Subaru's have those connections under the steering column. Everyone who's done anything with ECU reprogramming (e.g., Accessport) has connected these bits together and been startled by all the crazy shenanigans that ensue in the cockpit.

comment Catalysator broken? Odd rope coming out of the exhaust pipe
The reality is that it's a lot easier to replace the exhaust components one at a time. Each chunk is going to be somewhat hefty, rusted and annoying. You really don't want the whole set of components dropping on you at once. My suspicion is that you've blown some material out of the resonator. Its geometry implies a fiberglass collar around a straight air path. By the way, if you'd like a bit more back and forth discussion than will fit in the comments, please join us on the chat.

comment 1997 ford f150 lariat
Just to clarify to help get better answers faster: are you trying to get heat out of the heater? Or are you worried about the engine block temperature? Are you running long enough to build up residual heat in the coolant? Which specific thermostat did he replace? Please add more information to your original question.
