What causes a car battery terminal to get hot when trying to start it?
Possibly this1. If wires get hot when you try to start it and the motor is spinning over. Then the motor isn't starting and your over heating the cables by using the starter too much.2. If the wires are getting hot, but the engine isn't turning over then the starter is bad or the BIG wire going to the starter is shorted.3. If only one wire is getting hot at a connection, then you have a bad connection at that point. A symptom of this problem is everything electrical shuts off when you hit the starter.
What can cause a steering wheel to shake and vibrate?
As others have said, it’s usually down to wheel alignment or balance and is usually noticeable after a tyre change if the change wasn’t properly handled. Occasionally this can also be caused by one of the weights placed on the wheel by the garage to balance it suddenly detaching (though this is rare).However, if you notice any sudden change, I’d certainly advise you to stop IMMEDIATELY and check what’s wrong.One day, a few days after a tyre change, my steering started to noticeably start wobbling badly as I was overtaking someone at 70Mph on the motorway. Due to the suddenness and violence of the wobble, I assumed one of the lead balances had suddenly come off and I decided to pull in immediately to the hard shoulder but as I was pulling in below 40 Mph, there was an almighty bang and shudder in the car and I found myself watching the left wheel of the car running away into the distance - luckily off the motorway, into a field.I managed to steer onto the hard shoulder with the car running on 3 wheels and the brake disk of the missing wheel - it turns out that the garage hadn’t tightened the nuts well enough and they came loose and out mid drive.Motorway recovery eventually retrieved the wheel for me and as the tyre garage was within a mile of the motorway (and I was quite close to that junction) they drove me there with my car on their flatbed truck. The manager of the garage went ashen when I explained what had happened but as the only damage was an almost unnoticeable large but gentle dent in the bodywork where the wheel had hit as it went off on its bid for freedom, they were able to fix it with new nuts and get me back on the road quickly.Extremely scary experience though. Modern tyre garages tend to do a final tighten with a wrench for safety if they’ve used the compressed air spanner - something that hadn’t happened in my case. I now always ensure this is done before I leave the premises.
How do you tighten wheel lug nuts without torque wrench?
How do you tighten wheel lug nuts without torque wrench?Try not to.If you have to use a lug wrench, do this as a temporary measure (i.e.: changing a flat on the side of the road). As soon as possible, you need to have those lug nuts correctly tightened!Once upon a time, virtually all cars came with steel wheels and had drum brakes all the way around. With those, as long as you didn’t leave any of the nuts loose, you were generally all right.Nowadays, however, the majority of cars have alloy wheels and most also have four wheel disc brakes.Alloy wheels expand and contract at a different rate than iron and steel do, and after 50 to 100 miles lug nuts need to be checked and/or tightened, commonly known in the industry as ‘re-torqued’. This is because they can loosen after the first time! Additionally, unevenly tightened lug nuts can distort brake rotors (the ‘discs’ in ‘disc brakes’) so you get a noisy wobble when you step on the brake pedal.You don’t need a great torque wrench for lug nuts. The precise torque isn’t as important as making sure that all the lugs on a wheel are tightened to the same degree so the load is evenly applied. For most cars, I use 90 lbs.-feet, and 100 on light trucks using a slightly larger diameter lug. On a smaller car I might use 85 pounds feet. That 90 lbs.-ft. figure is assuming your lug nuts and wrench are 19mm or 3/4″. A 1/2″ drive torque wrench from Harbor Freight or a discount store should be fine for wheel lugs, though I’d suggest getting a higher quality one for most anything else. A ‘click’ type would be best, since it can be hard to read the scale on one that isn’t when doing wheel lugs. Just be sure that you STOP applying pressure when you hear one click. If you hear two clicks before you stop pushing or pulling, you’ve overshot your desired torque. Do be sure to reset your torque wrench to either ‘STOP’ or a low setting before you put it away in order to maintain some semblance of calibration.
