Not really. It’s a haldex system so most of the time it will behave like a FWD car. The AWD system is mostly for getting you unstuck or climbing slightly snowy hills and whatnot. It won’t make your car turn or stop any better in bad weather.

If you replace a tire that’s significantly worn you should replace its L/R pair at the same time, but thats generally a good practice anyway.

Not really. I’d say if you have a flat to still put a full sized wheel on the front and a donut on the back because most of your braking and all of your steering happens with the front wheels.

I think that with abs, traction control, vsc etc on everything these days, most if not all vehicles that come with a spare will have a full *diameter* spare so that the tire can be changed and the aforementioned systems won't freak the gently caress out. AWD or not.

You’ll have to change the rear diff fluid every so often. Interval is ~30k, but early and often is never bad.

Do you have access to service records? See if it’s been changed recently, consider checking/changing anyway.

I do! I have a total of 30 service records in the Carfax report on this car, and it mentions the front and rear differential fluid being changed in some of them. I will keep on this (planning on having all services done at the dealer where I got this, since its a Honda dealer

05 Crown Vic; I've been periodically refilling my AC refrigerant when the AC starts blowing warm. However this last time the gauge on the hose filler thing said it was over half full. Obviously I do have a leak somewhere but are there other causes for the AC to go back and forth between warm and cold air? Anecdotally it feels like after a turn or running over a bump makes it blow cold again for a bit but I haven't really tested it.

It's just silicone wax. Calling it ceramic is marketing hype.

Whether or not it's worth it depends on how much they charge for it.

My in-laws got their son’s Impreza’s tires replaced at Costco. They made a big deal out of being filled with nitrogen. The car sat a while and the tires went flat. They let it sit there with flat tires for months because they didn’t have a way to top it off with nitrogen.

Marketing works? gently caress.

Technically CO2 dissolves in rubber, meaning it's pourus to CO2. The second or third time you top off your tire the mix is like 90%+ nitrogen

The actual gain is it's dry since it's coming from a gas bottle. What comes out of an air compressor has (possibly, it depends) humidity in it. That moisture causes much larger pressure swings from temp changes than just gas expansion.

In racing where small changes in pressure have a big impact on performance it can matter a lot.

On a street car it's a scam.

Any gains you might see are equaled by checking your tire pressures on a semi regular basis. After a large temp swing being an ideal time.

Just drive don’t overthink, follow any owner’s manual recommended service items at the appropriate intervals. Those AWD systems are mostly “lifetime” fluid at the diff and probably more software than anything these days.

I agree on not overthinking it, but if you can change fluids always changes fluids at/before interval.

BMW still sells cars with no transmission fluid change interval at all, right? How do you pick an interval when the manufacturer says "Never"?

If it’s a sealed unit without a drain or fill port, than whatevs. It’s going to do what it’s going to do. Material science has came a long way, and I’m sure some units don’t need it/ won’t be the probable cause of failure if the unit does fail.

Google leads me to believe the Honda unit does have an interval and can be serviced. Takes about 2 quarts. ~$30-50 of fluids and limited labor.

Looks like a used rear diff for a CRV is ~2-300 bucks. New $1.5k.

So what, owning the vehicle for 100k, it would be like under $150 fluid to insure against a $300 part, and more costly labor.

Idk if that insurance pencils out, vs letting the dice roll.

I think the follow the interval if there is one, and don’t over think it is pretty fair.

I kept my 2013 CR-V in econ mode all of the time, which really should just be "normal" mode. The main thing turning "econ" off does is map the entire throttle travel to just the first 20% of the pedal, so that boomers who are scared to floor it "because it'll hurt the car" won't feel like they're crawling around all the time.

Found this helpful video explaining what it does
https://www.youtube.com/watch?v=eHCqSq68N4o
So it seems for some of my drives through the mountains in particular I should be turning it off to maintain a constant rate of speed but on the flats, and when the car isn't battling "black car, black interior, sitting in the sun" syndrome, I should leave it on.

I have a generally soft driving foot anyway, so I doubt I'll see much difference in gas mileage either way, but it was the cause of that hesitation in responsiveness I noticed when trying to speed up to pass.

I had a 2013 Accord, eco changed the throttle response and hvac. But in my testing, leaving it on for entire tanks vs off, there was no diff in mpg. I had a 95% highway commute back then though.

I was looking for something to replace my 1997 Buick LeSabre (which had developed some engine problems in recent months which appeared to be uneconomical to resolve, and then in recent weeks appears to have developed some weird electrical problem??), ran across the Celica on Craigslist with ~241k miles, and decided that the beginning of summer was in fact the perfect time to jump into a convertible with a stick-shift; my first time owning either.

It's been a blast, every time I put the top down I look for an excuse to take it out and drive it at least one more time in the day before putting the top back up for the evening, rowing the gears is enormous fun (still working on smoother starts and shifts :shobon: ), and it gets nothing but praise from anyone I've shown it to. I was a little hesitant at first but I've definitely fallen in love with the Celica.

Hey thread, haven't had to post here before but looking for some help/advice. My GF has a 2013 Kia Soul where the only external lock to get into the car is on the driver door. Unfortunately someone tried to break into it a couple nights ago and completely hosed up the lock cylinder and also managed to get it broken to the point where it cannot be unlocked and its stuck locked and unable to be opened/unlocked as all the internals are seized up. For now we had a locksmith pop the passenger door so its at least drivable. My question is how do I get at the lock/door latch mechanism so I can get it unstuck without being able to actually open the door? Any help or advice is much appreciated.

You shared it with a dick.

It won't open from the inside either? Does the window go down? Might take a talented someone to poke around through the window gap and see if they can manipulate the mechanism from above. Another possibility is to continue damaging the lock until it's removed from the door and doesn't jam things up anymore. Absolute worst case is you damage/destroy/cut up the door panel to get access from the inside and disconnect whatever is jamming it. I'd think you should be able to get a used door panel without too much trouble.

I did look it up and unfortunately you can't remove the door panel properly with it closed, there are 3 screws you can only get to with the door open.

Yeah it doesn't open from inside or out and the little lock switch is jammed in the lock position, whatever the thief did they really messed up the internals of the lock and door release badly. Haven't checked the window yet so not sure about that. Also having looked up how the door card comes off it seems like unless I can find a way to get it to release it seems like I'll definitely have to destroy the door panel to get it open.

Since the lock is already junk, I don't see why you couldn't just drill it out. You may damage the latching mechanism, but it's probably already damaged. Get medieval on it.

What you don't want to do is damage any part of the main door, it's the hardest thing to replace and have it look right. Unless the car is a beater, then do whatever. But the handle and door panel and any internal mechanism are all replaceable.

And i recently did this for a friend, his door got hit and wouldn't open at all, so all we needed to do was get it open once. I rolled the window down, and pried the door panel up and over its hook at the top, basically destroying it, and was able to fish out the opening cable and yank on it hard enough to get the door to pop open. It wasn't locked though. My backup plan was just to cut the outer sheet metal with a saw and peel the skin back, but again that was a damaged door that we were replacing anyway.

Probably the wrong thread, but is anyone familiar with CAN RE stuff?

I've got a PeakCAN adapter and I've figured out what I need to transmit by spending some time with PCANViewer but the software doesn't allow you to write loops or anything, some of the messages I need to transmit have counters or CRC.

What (free) software do people use for this, or do they really resort to writing a console application in this case?
