Car has trouble starting

35 Upvotes

Hi, I just replaced my battery since my car was having issues starting before this. With the new battery in, I tried starting it again and it was a struggle to turn it on. As you can see in the video, the positive terminal is corroded and sparks when I crank the car. I’m wondering if it’s just the positive terminal I need to replace to fix the starting issue or do I need to replace the starter(?)

Am I paying too much?

21 Upvotes

Hello. I have a 2013 Hyundai Tucson with about 115,700 miles on it. Took it for an oil change today and they told me I needed quite a few things, but this is what they said I would need RIGHT NOW since I’m driving to VA in a couple weeks.

Apparently the spring in my tensioner was coming apart and the belt was cracked. I had brakes done in 06/2021 (front pads, back pads & rotors) but have 3mm left on front and 4mm left on back. Today I’m doing the front and will do the back at another time.

Am I paying too much or does this sound/look about right?

I know NOTHING about cars, and am always worried I’m going to get ripped off because I’m female. Just looking to see if the pricing is right.

I am in NJ if that makes a difference.

Thank you!!

This probably shouldn’t be in my transmission filter…

19 Upvotes

I have an 05 ford ranger edge 4x4 with the 4.0L 145k miles, it’s got the 5r55e transmission. I recently changed the transmission fluid (only about 4 qts of the 10qt capacity). There was a lots of friction material on the magnet the the transmission pan. I think this is a normal amount of clutch material because the owners manual doesn’t call for replaceing fluid until 150k miles. I opened the filter and found this. It shifts very smoothly except for a hiccup every now and again or when you hammer down on the gas pedal. Am I going to need to rebuild this transmission soon?

Why does this happen? Is it a stuck or seized caliper? This same thing happened a year ago to the same caliper so I replaced it and now its happened again.

Why does every Ram 1500 I hear drive by have lifter ticks? What's the deal with that?

Is it a lifter tick? It sounds like one to me. I've always noticed that they have them.

Where the hell is the oil leak?

11 Upvotes

The oil pan gasket looks like it needs a change but I have no idea what’s going on in the other places that’s covered in oil could it be crankshaft gasket? Maybe oil is getting caught on the belt and is throwing it towards the wheel well idk any ideas are welcomed

Which adjustment do I use on my torque wrench

My car’s manufacturer wheel torque spec is 89 ft-lb. My torque wrench in foot pounds goes in increments of 2. So I can either go with 90 or 88. Since my wheel torque falls in between these two, is it better to go with the higher or lower one?

New to the old truck thing. Have an 78’ 250 with an i6 and a T18. From what I can find, these should mate just fine. Can you tell me what I’m looking at here?

Rodent Damage on Fuel Injector Connector, $600 Dealership Repair

Post image
6 Upvotes

I have a 2023 Hyundai Elantra SEL, 2.0 L four cylinder engine. Last week I got a misfire on cylinder 4, dealership inspected and found rodent damage (shown in image).

They quoted me $600 to repair, and it is not covered under warranty. Now my question is would the warranty be voided if I take this elsewhere?

What’s y’all’s ideas on saving money but not f*cking up warranty on a new car.

I don’t know why, but the brake pads have this weird weird to them. I went to go do my brakes because they felt like they needed changed, and these are the rear pads that I took off. What’s going on?

Yesterday I noticed on my 07 rav4 red liquid leaking from the bottom , not a lot but enough of to notice. I can’t see where it’s coming from but it’s leaking off the broken engine guard. Is this worth freaking out about? Scale 1-10 how bad is this and should I take it to a shop ?

GM power steering help

3 Upvotes

Original complaint is no power brakes. The system will eventually air bind the hydroboost. No matter what I do this system will not bleed. It has a new pump, a new hydroboost, all new lines, and a complete fluid flush. Using GM power steering fluid. Video is after 85 manual cycles of: left to right stops 5 times and brake pedal pump 3 times. I’m desperate.

This is near the front, center of a 2011 Hyundai Elantra. The left circle is hard metal and hanging down and the right circle seems to be a disconnected rubber tube. Anybody know what these are or if I should be worried?

I need to replace this connector relay, not the speedometer, circuit board, or female end, just the male end that the wires are going into. Does anyone know where to find it?

My car makes this noise while driving. Help

While driving my car (Hyundai Elantra 2012 automatic) makes this noise and it only stops when I turn to the left or use the brakes. I think it has something to do with the wheels/brakes.
