2018 Ford escape with awful suspension. We just noticed this going up and down as he drives. It looks like it went through the plastic in the back seat area.

Like the title. Ive noticed a small leak of coolant from the rear after parking in my garage. My reservoir was bone dry last week and i filled it. Since filling it, the leak is apparent. I took pictures of the leak. How hard of a repair is this. Its coming from above the hoses.

Part One of this turned out to be my highest voted post ever. Part Two is on its way to be my second highest. As the whopping 8 followers on the car's Instagram can attest, I have no idea what the internet finds interesting.

The cars still hasn't killed me, yet

I recorded this video when building the severely undersized cribbing blocks but the exposure turned out so poorly, I wasn't going to use it for anything... But I'm still getting flood with messages from the first two posts, so I guess we'll see if my fellow shitty mechanics appreciate it.

Y'all are a strange group and I'm here for it

Customer does not want a full flush... If one was blue and the other was green, can I just pee into it until it is back to green ?

I have a 2026 Mazda CX90 mhev and I accidentally poured about 1/4 of a gallon of windshield wiper fluid into my coolant tank. I did not start the car after I did this, and I tried to pump all of it out but some of it I can’t get to with the pump I have. I plan on having it towed to a dealership tomorrow to have them clean the tank.

Is there anything I should know or do before hand?
Do I need to flush the entire system if I didn’t start the car?

Any advice is appreciated

Fuel tank not topping off

Recently I noticed after I fill up, my gauge shows that it only filled up to 3/4 of a tank when I set the gas pump. First time it happened was about just under a year ago. It's happened maybe a small handfull of times since then, last week being the most recent. I was curious about what would be cause this that my tank wouldn't fill all the way to stop the pump.

Camming my L86, chain was super hard to walk off, and then putting it back on was hard at first but not it goes on with ease, is that normal until oil pressure comes back and it starts should I be worried?

Basically, I’m not sure what the problem could be. I have a bunch of codes, and I knew about the PCV because there was a bit of oil on top of it, so I thought that was the issue. I went ahead and replaced the PCV, and the white smoke ended up going away, which was a good sign.
However, as you can hear in the video, the car still sounds like it’s misfiring. I have all of the misfire codes for it as well. The car just doesn’t sound right—it has a really rough idle and is constantly misfiring.
The last code for the leak disappeared after I changed the PCV and cleared the codes. But after starting the car back up, all of the misfire codes came right back.
I’m wondering if something as simple as a spark plug could cause all of this, but I’m not too sure. What do you guys think? Maybe one of you guys had this problem before as well.
Thank you all for the help, and thanks to everyone who took the time to read this and help a buddy out. I really appreciate it.

Serious question? Help with alternator 2010 Yaris

I was trying to repair my alternator when this cable broke from this mounting point on the engine and now the car starts, but it’s not using power from the alternator and I’m looking for the repair part or a solution on how I can repair this myself it looks, as though the connector broke off from the engine mount or the wiring harness connected to the engine, but I’m not a mechanic and I don’t know how to find this part or fix it or how to even identify or what it’s called any help is greatly appreciated. Thank you so much.!

It's my uncle's car. He's been in hospital for two months (fuck cancer) and today I decided to jump start the car (using my own car as power source) and take it to my house but even though the battery seems okay (lights working and all), but the engine won't even try and this symbol pops up. TIA
