I recently found out that the Jeep Renegade disables its starter when it's below -30C and no block heater has been plugged in. This is not documented in any Jeep manual, but it is in the Fiat 500x manual (same platform). There is no way around this, other than to plug it in and/or wait for the temperature to come up. I feel like this is dangerous. If you for some reason didn't plug it in (or had a power outage, or were somewhere without power and the temperature dropped) and needed a vehicle for heat, or had an emergency and needed to get somewhere immediately, you'd be SOL.

I've checked the Italian manual from a MY21 driven by one of my colleagues, there are multiple reference to preheater in the manual for diesel units. Maybe they forgot to write it down for the EN-US translation?

Wouldn't the diesel be slushy or just plain frozen at those sort of temperatures?

It's not like life stands still when there is polar vortex over Canada/Northern US for a week with -30 and colder in many places. Sure there will be some no starts and some cracked parts from improper antifreeze mix/winter prep, but it's absolutely commonplace with many places at -40 or colder for many days on end, if not weeks a couple times during winter. Nobody would argue it's good for the engine, but with proper antifreeze mix and oil weight as most do in those areas (60/40) it's not the end of the world. Diesels used to be notorious to start and often kept running for days but that's not as common anymore.

Yeah, I was going to say isn't a "proper" coolant mix good down to -45? At -30 you'd think thats far enough away that it would be ok. Maybe once you get below -40 it would start getting close to frozen

It was a friend working on his partner's car. I don't know what year. The (if equipped) line just makes it too. Not equipped? Whoops! You're stuck!

plus people aren't usually keeping cars on the road for a decade or more so maybe they don't notice how glittery the oil is

There was a half inch long gear tooth on the magnet drain plug on a friends 91 Miata track build that she picked up as an abandoned project. Also the fluid looked like a cross between bass boat paint and an AARP members bowling ball. Drained it and hmmm whats this  Oh that don't look good  Unlimited slip differential  The current plan is find a decent source for a pair of new Koyo 33007 carrier bearings cheap, a set of ring gear bolts, and I'm gonna run this whole limited slip carrier through the parts washer one piece at a time, reassemble it, slap the new carrier bearings and spare open diffs ring gear on it and put it into the spare open diff housing. Since the pinion bearing depth is already set on that housing it should be a matter of taking a contact pattern+backlash before pulling the open carrier out and then adjusting the side adjusters till that pattern and backlash are back, then sending it. I wish I could figure out why it ate most of the teeth off one side of the pinion but only beat up the teeth on the ring. Normally I see the opposite or all the teeth on the pinion gone. How did it do this with the engine running? Would expect the pinion to be damaged pretty evenly all the way around. Maybe heavy shock load (with a 1.6? How?) hosed up the pinion and stalled the engine and the inertia of the car just stripped everything off that side of the pinion after? Maybe it lost a couple chunks of teeth that wedged the pinion bearing and the inertia of the car ripped the pinion teeth off first? What's your guess?

Then at we got to the point where most anyone can get into any vehicle and operate it with intuition. We’ve been drifting away from that more and more and we probably need to coalesce around a UX that makes sense for modern vehicles including electrics rather than doing all these ‘one of’ designs dictated by the person that styles the dashboard. If driving is a confusing hassle, people will be more enticed to buy the more expensive self-driving models.

Powershift posted:The other check engine light. Thats fuckin art. As far as the hot exhaust manifold and turbo, I saw it on Fakebook I think and the caption said something about they didn't do an injector service, one started leaking and dumping fuel which ignited in the timbo or something like that. Obviously take that with however many grains of salt you wish.

Keep in mind when you see pics of red-hot things that cameras will often pick up some infrared that your eye isn’t seeing (there’s IR-blocking filters on cameras but some extra usually gets through). Go take a photo of the heating element in your oven when it’s running and compare to what you’re seeing, it’ll be even brighter in the photo. Edit: sorry about my old oven that needs cleaning

Hum, the polestar/volvo setup is like that. Stays in middle and nudge forward for reverse and backwards for drive. It lets you do it while moving, so you can rock the car on snow etc.

You reminded me of a fun experiment I did with my goddaughter ages ago, so here is a picture I took a minute ago in a completely dark room, that's the IR transmitter on the front of my TV remote when I press a button.

I wonder if maybe the engine seized at speed and did that rather than exploding the transmission?

When I worked at a consumer electronics store we would do this all the time to determine if a customers remote they brought in was actually dead or if it jaur needed new batteries. Wes pop in a fresh set point it at a digital camera or our flip phones lovely camera and mash some buttons to see if it lit up.

Darchangel posted:I wonder if maybe the engine seized at speed and did that rather than exploding the transmission? Interesting theory, it's possible. It was bought as a non driving project this way so I'm not sure if the engine was replaced before they gave up when it still didn't drive, or what. It runs now though and I know my friends didn't replace the motor (yet). Allegedly the sellers were running it on 110 octane with some different tune tune from stock but it's got no other drivetrain mods I'm aware of. Driveshaft was pulled thinking that the transmission was shot but it still had to be dragged on and off the trailer due to the hammered diff. It was scca stock modified class car #8 if anyone knows the previous owner and can get the story on what happened right before it stopped driving.

You can also use your phone camera to check for signal in 1310nm/LR fiber, which has been useful. The 850nm/SR stuff is visibly red (it looks like the same red as TOSLINK to me), but the invisible infrared stuff needs some technical assistance. I really hope these signal strengths are as low as I think. e: 850nm is already IR, so I guess the faint visible red is either the tail end of what we're sensitive to, or the cheap LED transceivers are producing more than one wavelength. e2: Consensus seems to be that this sort of inhouse 10gbit gear isn't likely to be dangerous, but it's a good habit to never look at it anyway. Fair enough, phone camera it is. Computer viking fucked around with this message at 17:35 on Feb 13, 2024 |
