I'm trying to sell some winter tires, and the dude has asked for the dot code, which should be a four digit code, but all I can find on the tire is this "DOT XH MO N247". What does that mean?

They're basically asking how old the tires are. If that's the actual DOT code, those tires are at least 20 years old. 247 is week 24 of the year ending in xxx7 (likely 1997) - in 2000, they switched to a 2 digit year. This may help.

Then you're very likely misreading the code, or your tires are following a nonstandard date code format.

That's not the complete DOT code. There's a set of 4 numbers a bit past the end of that code, they may look recessed or stamped differently. Sometimes the complete code is on the other side of the tire - look at the other sidewall and you'll probably find the rest. If it's still not there, time to call Pirelli - (800) 747-3554 randomidiot fucked around with this message at 11:55 on Oct 27, 2017 |

Why does my 04 ford taurus develop a noticeable shudder at idle?
It's the transmission isn't it?

The only other viable options would be: *If there was a factory HID option, install that *Buy an actual known good projector housing and retrofit it into your existing headlights. Done properly you'd end up with the same results as an OE set. Neither of these are cheap or easy on most cars, though.

Jack B Nimble posted:Why does my 04 ford taurus develop a noticeable shudder at idle? If you have a tach you can determine if it's moving forward or if it's dropping revs. The way you're describing it, sounds like a rough idle. Is the CEL on? Also, is it sort of like, inconsistent with revs? Does it rev up, then down slowly? Might have to pop the hood to listen for it. My first guess would be when you come to a stop it's got issues coming to idle so it under revs then catches itself which can feel pretty rough. Also, try putting it in neutral at idle and see if anything changes. NOW a stupid question of my own! (for a friend) So, MY FRIEND can only afford one pair of winter tires at a time. They are going to go on a RWD pickup, an '85 d100 to be exact. MY FRIEND thinks he'll be best served with the tires in the front, as that's where most of the braking comes from and since there is no ABS in the vehicle front-wheel traction seems pretty important. It seems easier to correct a back end that's slid out then it is to save the truck from sliding everywhere and not being able to brake properly. Thoughts?

PuTTY riot posted:Is upgrading my 2012 accord's lovely headlights to this a terrible coffee-can-exhaust-tier idea? Is there a better choice? I have OEM HIDs on my Odyssey now and they're great. Driving the accord at night feels like I'm using my iphone flashlight to see on unlit county roads. Could be mistaken, but a cursory Google search seems to indicate the lowbeam bulbs are H11s, in which case you can do a H9 swap. They're essentially the same bulb with higher draw (trades shorter lifetime for higher output) so beam pattern will stay the same as the OEM bulbs but you can nearly double your light output. Base of the bulb will need slight modification (need to trim a mm or so of metal off the key so it will fit in the H11 housing) which can be done with a dremel tool or good pair of side cutters.

That being said, mismatched tires like that are a recipe for disaster. The truck will respond unpredictability in snowy conditions with that configuration - with seasonal tires replace all four or none at all.

Good catch - I misread it as 2 new winter tyres, assuming that they were paired with two old winter tyres. Mixing is just wrong and I'd rather get 4 part-worns or lovely Chinese brands than do that.

So I picked my car up from Pep Boys and with it came a detailed breakdown of that $900 thermostat quote: $207 for the thermostat, $175 for the labor to replace it, $135 for a "complete tune up package", $90 for a "3 step pro fuel package", and $97 for a complete coolant exchange. Which doesn't add up to $913 even with the $90 the bastards charged me for just doing the engine diagnostic (you plugged a little thing in and read error codes off it! I'm not that ignorant!), but what loving ever. So for those of you who wanted to know where they were getting that number, there you go.

I bought a set with halos but it turns out they are not DOT compliant/for off road use only so I likely won't want to use them, and OEM originals suck. Are they just round sealed beams? Two things, put in a relay so they can get the most power from the battery, instead of routing the power through the switch. Also known as a bright lights kit, but I just bought the parts loose and put it together. Second, buy some Hella housings that take modern bulbs. They have DOT patterns and Euro (not DOT) patterns and most people prefer the euro ones. It’s more of technically breaking the law than blinding people, as it’s a different light pattern but still a pattern approved by authority, but the choice is available. I suspect that’s why your current ones are for “off-road only”. Also I think halo lights are dumb and ugly on old iron.

Those of us with the superior quad-5.75" sealed beams don't have all the options that everyone with 7" sealed beams have, since the Wrangler market has kept 7" sealed beam replacements a hot seller. I have a relay kit and some Autopal 5.75" H4 housings all sitting on the shelf to go into my truck.

Find the location of the condenser for your A/C unit, and figure out what filthy stuff the condensation is dripping into before it drips under your car. The condenser looks like a radiator, and may be built into your car's regular radiator, or it might be separate, often located in front of or just behind the radiator. Alternatively, give your engine compartment a good thorough cleaning with some Simple Green and pressure water, let it dry, and then give your A/C a run and see if the water that drops out is now clean instead of yellow.

I thought the smaller ones got the same love from Hella on design. If nothing else a relay and good quality new bulbs should help. Personally I’d swap them to the ECE housings. I understand why you may not want to. Check out images of the different lighting patterns. I agree with you on DRLs being safe and that’s a good goal on an old, unsafe car that’s your baby.

You can have DRLs that aren't halos and thus don't look stupid as hell. Enourmo posted:Side note: "DOT APPROVED" just means the physical bulbs meet the size/connector specification to be labeled 9006 or whatever, it absolutely does not mean any regulatory agency has approved the kit for road use. No. There's no such thing as DOT Approved. DOT doesn't approve anything (you're right on that bit). The DOT stamp on a light indicates that the manufacturer certifies it meets FMVSS Part 108 requirements, which includes a hell of a lot more than the socket design. I'm not sure what it takes to get an investigation going if someone's fraudulently stamping their products, but the NHTSA has and will levy fines/prosecute. In general, you're not supposed to replace one bulb type with another unless you replace the housing as well. Often the new bulb's light is emitted from a different position on the thing, which changes the pattern of light reflected by the housing. So who cares about all that crap, right? Well yeah it's not likely you're going to get in trouble unless your lights are just throwing light everywhere and it's painfully obvious to a cop, but if you're out there blinding everybody in the opposite lane you're an rear end in a top hat and you bought a lovely product. Some states that have vehicle inspections will give you crap about it and might fail your vehicle...Pennsylvania has a bad reputation for this, and Utah to a lesser degree. It's a common complaint with Jeeps in particular, since there are a thousand 7" lights on the market that are vastly brighter than the garbage OE headlights, but only a dozen or so have DOT markings and they all cost 3-10x as much as the ebay garbage.

To add a bit to that, the DOT, as mentioned doesn't approve anything, it just sets out regulations that manufacturers are expected to adhere to. But they don't actually test poo poo, approve anything or otherwise tell you (a manufacturer) "yes this is approved".

I had my car sprayed with Krown Rustproofing for the winter yesterday morning... Of course... I hit a skunk with the front driver side tire tonight and the car now smells horrible both inside and outside. I *have* to wash my car. Most likely the smell is coming from underneath because of how I hit the skunk. How much am I wasting the Krown spray treatment by getting the car washed *including* an under spray?

The question wasn't aimed at you, it was a rhetorical rant kind of thing. You can always install them and see if they're good or not. I don't know how much labor it is to swap the housing on your car.

Another update on the Turismo, after retiming the belt from scratch it finally runs and idles. Highlights include discovering the flywheel is installed 180 out making the timing mark useless, missing AC mount bushing, worst motor mount I've ever seen (It was basically two bits of metal pretending to be a mount, I didn't dare look at the others), big flames out the exhaust and carb, and distributor off wrong year car causing me to have to rotate the wires one to the right and set the adjustment at the far end of the range. Starting the car requires pumping the gas a couple times but once it's going it sounds good, no knocking so far. So now that it runs I need to set the carb since it idles high and find a replacement coolant temp sensor harness connector since the last owner cut it off. I don't know why I do this to myself.

It's only a pain in the rear end because some lights that are the right size don't have the same geometry around the plug and would require me to cut a part that's not manufactured any longer and would be a legitimate pain to fabricate. I'm not fond of that idea, but we will see what happens when it is back in my garage. Ultimately what I will end up with is what works best and is safest.
