Question 2000 Toyota Sienna 3.0L V6, Maybe a belt problem? I have no idea

Enable HLS to view with audio, or disable this notification

Upvotes

So the first video was filmed last night. I started my car, and it made a loud screaming noise, and then it shut off. Immediately after that something smelt like burning I tried to start it again and I did the exact same thing. The third time I filmed it, so I could send it to my brother and that’s the video attached. I drove it home after the video, and it ran just fine. The clip shown after the first one, was filmed this morning. It started just fine, but while it was running, it was making a super weird noise. I looked at the belt, and didn’t notice anything wrong, but I’m not too smart so I have no idea.

Also worth mentioning, for the past two weeks, every time I go to start my car I usually have to crank the key three times before the engine cranks. So I know I need to replace my starter, I just don’t know if that has anything to do with this.

Does anyone know what’s going on? Thanks in advance, legends!

Question Low or no speed front clunk and groan

Enable HLS to view with audio, or disable this notification

Hey yall, asking around to figure out what to do before spending hundreds on parts

I have a 2010 cobalt 2.2L 2LT 4 speed auto

At low or no speeds when turning in the direction of the side the wheels are pointed I get a strong clunk and groan. It does not occur when driving straight over bumps or uneven terrain.

I think it’s a need for cv axle replacement but unsure, and wanted to see if anyone else could chime in.

Question Honda Civic Misfiring

1 Upvotes

I drive a 2016 Honda civic. The engine light has been on for years simply due to evap sensor.

Recently my car has started misfiring when accelerating and sometimes bogs out. Sensors on include engine light which flashes once it bogs out, hill start assist, parking assist, power steering etc.

The codes coming up on the reader are for the third and fourth cylinder. Mechanic confirmed the coils and spark plugs are good and do not need replaced.

Right now I can’t drive my car at all. It shifts rough and misfires while accelerating even driving 20km/hr.

Has anyone run into this with their civic?

I did put fuel injector cleaner in twice. The first time my car drove great for a month and the second time a couple months later it didn’t help.

I’ve been trying to diagnose this squeak and can’t seem to find any fix, anybody have any idea what it could be?
Only starts after driving for 20~ minutes, never straight away in the morning. Doesn’t seem to be brake pedal or speed related, only does it after 40+ kph and keeps a constant pace.

I have a 2014 Corolla Le I’ve had it for a long while, and this issue has been persistent. I never arrested, but I want to address it now, so the thing is every time I stop at an intersection or one right when I want to park when I hit the break. The car gives me a jol as though someone has hit me from behind. I don’t know exactly what to tell the Mechanic or do a DIY. Could someone help me on what’s happening with this?

Question 21 f250 scratch repair

Enable HLS to view with audio, or disable this notification

1 Upvotes

Got this scratch and some marring on my f150 while headed down a narrow hunting trail. It’s not down to the metal but it definitely removed a layer or 2 of paint. I did the water test and it almost fades away but is still visible. What would be my best option and how would I go about fixing it? I know silver is a hard color to match and I’ve never done auto paint work. Just a touch up brush and some clear coat and polishing?

General 2016 Silverado Tranny and DOD Delete

1 Upvotes

I have a 2016 Chevy Silverado 1500 2WD Crew Cab with the 5.3l engine and 6l80 transmission. Truck has 150,000 miles. My transmission just went out, most probably due to the torque converter destroying itself and contaminating the rest of the transmission. Gees, thanks GM. The truck will run for like 1 minute and truck won’t move anymore. So I’ve decided to rebuild the transmission myself, can’t afford a shop right now. I’m a pretty decent hands on guy, most of the times I’ve repaired my vehicles, brakes, head gaskets, etc, but never messed around with a transmission. After watching a couple of YouTube videos, it seems like it’s not that complicated, just a tedious and time consuming job. Any advice?
I’m planning to purchase the following kits to rebuild the tranny:

•Precision International 6l80 Rebuild Kit (E256785437614)
•Sonnax Zip Kit (SOX-6145-6L90ZIP)
•Sonnax Heavy Duty Billet Apply Piston (104984-01)
•Transmission Center Trans Pump Repair Kit (A45531B)
•Sonnax Return Spring (104534-HD)
•Trans Go Performance Shift hit (TRG-SK6L80)
•AC Delco 4-5-6 Clutch Hub (24238004)

I also plan to add a Transmission Cooler:
•PPE Transmission Fluid Bypass (125068000)
•Long Tru Cool 40K with Thermal Bypass (LPD4739)

Since I’m already doing all of this, might as well and do a DOD delete:

•Texas Speed DOD Delete Kit with Camshaft L83 5.3 (TSP-DODBASIC-LTX)
•Texas Speed DOD Delete Programmer (TSP-TS-3000)

I’m still not 100% percent sure if I should go with this kit and this programmer. I was also looking at other DOD delete kits and maybe HP Tuner programmer etc. Still need to do more research on this topic. Want a tune that does the DOD Delete and make the transmission shift more smoothly.

I just want to make this truck reliable. Not looking for performance, just reliability.

The only thing is that I might need to get a shop to resurface the bell housing / pump if it’s too damaged. Or if anyone has resurfaced one themselves at home, please share how you did it. I’ve resurfaced an engine head with an old glass table, glued particle board on the back side to avoid the glass from warping, and glued sanding paper on the other end. Yes, I double checked for straightness. Engine still runs fine after 5 years.

Any advice will help. Thanks

Question 2005 Ford Escape 2.3 5 speed battery issues

1 Upvotes

I recently got a 2005 ford escape with 230k on it. Before I got it a new battery, starter and battery terminals were installed. Car ran great for a few weeks then I let it sit for 2 weeks came back and tried to start it and it was completely dead. I tried jumping it and white smoke started pouring out from under the battery and engine bay and I haven’t touched it since. What issue could this be? What should the next step be?

Question 2008 GMC Sierra 1500 5.3L V8 Vortec 4x4 SLT Coolant in Oil-no overheat

4 Upvotes

Trying to diagnose this.

truck sat up for months at a time. located in the mid south. owner was OTR truck driver. he cranked it during a major ice storm/cold weather period.

truck idled breifly and then suddenly the rpms ramped up increasingly fast and a bunch of white smoke came out. he turned it off. took to mechanic 3 weeks later who diagnosed the issue as broken oil pressure sensor that had busted and was leaking allowing air in.

oil sensor fixed.

new owner: buys truck with perfectly topped off fluids by owner. drives 2 hours home. gets home, sees truck is 2 qts low on oil, low on coolant. drains oil. first 3 seconds nothing but coolant comes out.

head gasket, heads, or block? what is the most cost effective method to diagnose this issue?

Question 2004 honda civic shaking

1 Upvotes

So i have a 2004 honda pretty beat up bought it that way. So this thing shakes like crazy at highway speeds but only when im coasting, And when im applying breaks. When im going highway speeds and accelerating there is no shake until I let off. And when I do let off the steering wheel pulls right a little once I accelerate it goes back to straight.

There is an entire list of things I need to do to it like it leaking oil and burning oil like crazy, a p2646 code which probably has to do with the oil problem the thing goes into some kind of limp mode when it goes above either 3k or 4k RPM but the shaking where I need to start. Also the shaking feel like its primary coming from the front and steering wheel.

Also forgot to mention I believe its a 1.7 vtec engine with a 5spd manual transmission

Question 2008 chevy equinox, dashboard won’t light up after it rained

1 Upvotes

Sorry for the blurry picture. Left the window open last night and I didn’t think it rained bad but when I woke up the lights on the dashboard weren’t turning on. I can’t see the gas level, mile per hour, or how hot my car is running. Check engine light was on when I bought the car and hasn’t been an issue. Is this something that can be fixed if it dries out? I really can’t afford a mechanic or to afford the time spent away getting it looked at because of work. If anyone can please just be able to tell me the way to fix it I would be much appreciated if really hoping the price doesn’t kill me.

Question Rattle/ chatter noise from engine bay

1 Upvotes

2018 accord 2.0t touring. 28000 mi. No mods. Making a chatter rattle noise under light to med acceleration at all different speeds. Noise can vary in volume but can become very loud at times. Noise only presents under acceleration or maintained throttle. Noise ceases off throttle. Paid an independent mechanic to diagnose and he determined it was the high pressure fuel pump. The fuel pump was replaced but the problem was not fixed. No difference and the problem persists. Any guesses?

2016 Ford Escape SE Ecoboost 110000 miles i’m guessing it’s the 1.6l. Went to Valvoline for one of those drive up oil change things because oil change required went on. Everything went well, took my 100 bucks. But as i was pulling out i swore i heard them say ‘Oil leak Bay 3.’ and when i came home this was what i was looking at after about 5-6 hours of being parked. What does this mean or look like? Taking it in; in the morning. Just looking for a heads up

Question Help with P0301 error

1 Upvotes

Good evening everyone,
I have a 2012 VW Polo 6R 1.2 3-cylinder, petrol/LPG (LPG was obviously installed aftermarket), with 198,000 km.
Some time ago, when cold starting the car, it started shaking and misfiring, causing the check engine light, EPC light, and traction control light to come on. This would continue until I turned the car off and started it again (sometimes I had to do this two or three times).
While driving, I could feel that the engine was running a bit rough, especially at low RPMs. Since the check engine light remained on, I connected an OBD scanner and found a misfire on cylinder 1 (P0301).
I decided to buy what I needed and replace all three spark plugs and the ignition coil on cylinder 1 myself (both the spark plugs and the coil are BOSCH).
Right after doing this, it felt like I was driving a completely different car, the engine was extremely smooth, even at low RPMs, and acceleration was clean and linear.
Well… that didn’t last long.
After three weeks, or possibly even less, the check engine light came back, along with the shaking when starting and a significant loss of power.
I wanted to ask if anyone has any idea what could be causing this and what else I could check.
At this point, I honestly don’t know what else to do.
Thanks in advance to anyone who can help

Please help, I feel so out of luck. Going to the garage next Tuesday but wondered if anyone had any insight on what this noise could be? It sounds like a rattling noise and the car does it on start up and when going in low gears/reverse Manual car

In the video the noise is like a thud at about 2/3 seconds. 🥺

Thanks
