comment Does the advantage of ballast make minimum weight rule pointless?
This question appears to be off-topic because it is about race regulations and race car design, not motor vehicle repair. Also, I would add that the minimum weight is not necessarily solely (or even primarily) directed at ensuring safety. It may be about leveling the playing field, as lighter is faster. There are minimum weights in sailboat racing, bicycle racing, etc.

comment How can you tell the difference between oil or transmission fluid in the antifreeze?
I wonder if leak detection dye (UV dye) added to the engine oil might be a way of isloating the leak to either engine or trans. Not sure the concentration of the dye would be high enough by the time it makes its way into the coolant system though.

comment 1999 jimmy with no heat in the cab
my first suspect would be a damper/diverter valve that is supposed to direct air through the heater core.

comment Daytime running light failure — one side only
OK, since it's dual filament, is the low-intensity DRL supposed to turn off completely when you engage the turn signal, or not? in other words, are you expecting the blink sequence to be hi-lo-hi-lo or hi-off-hi-off?

comment Does the advantage of ballast make minimum weight rule pointless?
@Tik I'm not sure I agree that "even in earlier days, you simply could not afford to have your star driver killed." Driver safety was not historically that big a concern to the vehicle engineers or the race track designers. This gradually changed I think it's fair to say that safety has steadily become more important in racing, especially F1.

Does this car use a single filament turn signal bulb or a dual filament turn signal bulb?

comment My car won't start. Is it that I ran it without coolant or is it my battery?
When you say you had zero coolant, you mean that there was no coolant visible in the coolant "bottle," or that you opened a coolant drain at the bottom of the system and nothing came out? If merely no coolant visible in the overflow bottle, then you were likely low on coolant, but not out of coolant. Either way, wouldn't prevent you from starting the car unless there had been some serious drama (major overheating) the last time the car ran. This would not have gone unnoticed.

comment Rear suspension much more sensitive to bumps than front
@vlsd depending on the bushing geometry, you may be able to put some load on the joint with a prybar or something and observe the way the bushing reacts. You may be able to tell which are most worn in this way.

comment Washing coolant system with dish soap to remove oil residue
Perhaps some context would be helpful here. Are you recovering from a blown head gasket or something similar where you know you had some quantity of oil in your cooling system, or are you considering this as routine/preventative maintenance?

comment Rear suspension much more sensitive to bumps than front
what type of vehicle? most likely this is not something "wrong" with the vehicle, merely a consequence of suspension design, weight distribution, and physics.

comment Hyper-miling and stress on engine oil
@BlessedGeek you seem to be insistent on not following general recommendations, so the only way to make an educated choice about when to change your oil would be to send a sample of your used oil out for analysis. Probably multiple samples at 5k mi, 6k mi, etc. Its the only way to know how far you can stretch your oil changes with your car and your choice of oil and your driving style. Also, you could spend a couple of years over at BobIsTheOilGuy. Or you could just change your oil.

comment 2005 Chevy Cobalt front speakers silent
have you checked the fader/balance settings to make sure they didn't get inadvertently set faded all the way to the rear?

comment Hyper-miling and stress on engine oil
How do they define "necessary"? As I said, if you really care about getting it right, send the oil out for professional analysis. If you want to be safe, follow the manufacturer's recommendations.

comment Differences and Recommendation between Steel and Alloy Wheels for Winter?
If the paint on an alloy chips, you can get oxidation of the underlying alloy metal. It won't be red like rust, more typically it will be chalky white. If you catch it before it gets horrendously bad, its simple to clean it up and throw some touch-up paint on to keep the oxidation from spreading.

comment 1999 GMC Sonoma 2.2L, 5spd, SLS - no reverse lights, suspect transmission
just a thought--might the switch be damaged/worn such that, even though it works electrically, it is not being depressed far enough by the trans to complete the circuit?

I saw the CW designation. was hoping the OP would take another crack at it, or failing that, that someone from the community with the knowledge.

@JuannStrauss Huh? how can the exhaust "suck" anything? Which "oil seals" exactly are you talking about?

comment Tools needed for oil change on 2012 Honda Odyssey?
presumably also some kind of wrench to remove the oil pan drain plug... tool sizes and oil quantity would be helpful additions.

@SamWhited might want to specify clutch master and slave cylinders. Also, could be worn synchros on 3rd gear.
