Physical safety Modern cars are amazingly more safe than classic cars. Guys that are into classic cars frequently throw around phrases like "They don't make them like they used to!" or "This is built like a tank with real American Steel!", but when you look at a classic car in an accident, the results are pretty obvious. In 2009 this crash test was done ...

I wouldn't touch the odometer. The rule I always subscribe to is that the odometer measures how far the chassis has rolled. Otherwise a person could go mad trying to figure out which repairs/replacements should reset the clock. (Obviously not tires or wheels, but wheel bearings? Axles/driveshaft? Transmission/differential? etc...) It also makes sense when ...

Car batteries are not only rechargeable but are constantly being recharged by the alternator. Simply starting the car takes a lot of power reserves from the battery, then electrical systems such as the headlights, screen heaters, ignition and injection systems all draw on the battery. When the engine is running, the alternator is near constantly providing ...

Those appear to be wheel weights. When mounted on the rims, tires are often not totally and absolutely balanced. When you drive, it may cause all sorts of shaking issues if it is badly out of balance. To compensate, the mounter will spin the tire and get a reading on how to use weights on the rim to compensate for the out-of-balance condition. They are ...

No, they are not safe Safety standards dating back to before now were not as stringent as they are now. The further in time you go back the less safe they become. Safety has been driven by governments and as regulations have become more stringent over time car manufacturers have had the responsibility to conform to the compliance stack of the time. ...

All electric motors consume more current at startup compared to steady state. Check out the label on your fridge for example (or look at this one): the max current on the label is 2-3 times higher than the value you'd obtain from power to voltage ratio. The reason behind this lies in the properties of electric motors. Approximately, such motors have torque ...

This is a wheel balancing weight. This type is held onto the inner side of the wheel with double-backed foam type adhesive tape. The the "1/4" stands for one quarter of an ounce. The "FE" denotes that it is made out of iron. Others are made from zinc and lead. Lead type are banned in some countries and states. It is important and needs to be replaced if ...

I've never replaced an odometer when replacing an engine. What I will do, however, is make a note in the cars documentation that the engine was replaced at xxx,000 miles with a new/refurbished engine with xx,000 miles. I also keep all the receipts of any ancillary parts replaced at the same time (tensioners, water pumps, etc), so that a new buyer can see ...

No, hubcaps are purely cosmetic and do not need to be fitted. Some designs improve fuel economy and reduce wind noise by having a fairly flat surface but a car with one or more missing hubcaps is perfectly safe and in the UK, for example, hubcaps are not required to pass the annual MOT (safety inspection).

You are right in the thinking of using less gas and that's exactly what the purpose was to have the start/stop feature. The main goal of doing it (at least here in the States) is for zero fuel consumption/zero emissions while the engine is stopped. This provides for better overall fuel consumption numbers to meet what the EPA has mandated for companies to ...

You've already seen the safety comparisons. With that being said, classic cars are for fun. If you're looking for safety, a classic car isn't for you. If you're looking to have fun, go for it. Like most things in life, there's a balance that you have to evaluate. No one can answer that for you. You have to do it for yourself. Are you willing to take ...

The oil problem You can run any engine speed you want as long as you keep the oil pressure up. Because of the impossibility of getting a roller bearing down a crankshaft, engine bearings are "plain bearings" with polished steel floating above babbitt (a soft metal). The oil pressure makes the bearings "float", so the dynamic forces of pistons being ...

What is a Differential ? A differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the ...

Classic cars are significantly less safe than modern cars. In a classic car, it is both harder to avoid a crash and more likely that you will sustain serious or fatal injuries in the event of a crash. It's the former point I'd like to emphasize in this answer. First, a classic car will not have features like ABS, traction control, or stability control. This ...

No. Vehicle weight is only one factor of fuel economy. The most important factor is air resistance. Vehicle weight comes as the second most important factor. My ~1700 kg (car + driver) Toyota RAV4 hybrid has 56 litre fuel tank. Gasoline has a density of 0.735 kg/litre. This is 41 kg of fuel. If you reduce it by half, you save about 20 kg, or a bit over 1% ...

Unless you touch both battery posts, your body isn't completing the circuit from - to + The voltage is not high enough to overcome the resistance of your body (under most circumstances) The most dangerous aspect of automotive batteries is that they give off hydrogen gas. If you create a spark close to the battery, its possible to ignite the gas, causing the ...

Yes, you should fill your tire. The fact the other tires all are nominally correct means you should trust your gauge. Modern tires often have reinforced sidewalls that mask the appearance of low pressure. Waiting for a bad wear pattern is not a good plan, as then you'll have an unevenly worn set of tires.

While i'm not sure if there are mechanical tachometers like speedometers electronic tachometers are quite simple. An electronic tachometer works like an old analog volt meter. The speed of the engine is converted to a voltage. The voltage is fed to the moving coil. The coil creates a magnetic field. That field of the coil tries to align itself with the ...

You're asking two different questions - are they safe, and are they as safe as a modern car. For the second question - No. An older car without all the modern safety features will not protect you, your passengers, or pedestrians as well as a modern car will in the event of a crash - You don't have airbags, crumple zones, ABS, NCAP ratings and so on. For ...

Given the assertion that most car accidents occur at speeds of 12MPH or less, most classic cars should be considered safe. Your odds of surviving a crash at parking-lot speeds are very good. However, your chances of walking away with only some bruises are much lower than with a modern car. In even a walking-speed collision, a classic car is going to transfer ...

It takes a LOT of power to get the rotating assembly - crank, pistons (or rotors), etc. - moving. For reference, try turning your engine over with a breaker bar on the crank. It's not super-easy (though some of that is due compression). All the parts in the rotating assembly - crankshaft, connecting rods, pistons, valves, camshafts, timing chain - add up ...

You can put your car into neutral by moving the gear selector into the position marked "N".

You're probably better off not replacing the odometer. You will need to keep accurate track of how far the car has been driven in total, so if you were to later sell your car without disclosing that the actual mileage is the new odometer reading + 220k miles, you could be found guilty of fraud. You certainly don't have to replace the odometer, and it will ...

Yes it can be easily done, but based on your scenario it's not necessary unless you want to sit for extended periods without running the engine. If you are going to leave the vehicle running for Air Conditioning for instance then you don't need to do anything it should work fine as equipped from the factory. Here are some things to consider If you still ...

I would refer to it as a CV (constant velocity) joint spider.

Looking at this page, it shows the curb weight of a Volkswagen Passat B5.5 1.9 TDI 130 6sp to be 1342 kg. Subtracting this from your number, it comes up with 83 kg for your driver weight, or about 183 lbs for us 'Mericans ;-) This should be fairly close as long as it is the same spec as yours. It should be fairly close, though. I'd imagine there are some ...

In the event of an accident, how does a classic vehicle compare to a modern machine? Badly. Are safety features on new vehicles really a life saver? Yes. Can anything be done to improve the safety of classic vehicles? There are certainly safety improvements that can be made. You can fit better brakes and tyres. You can sometimes retrofit collapsible ...

Putting the transmission into "Park" engages the "parking pawl" - essentially a metal pin that locks the output shaft of transmission (and thus the driven wheels) in place. As to why it exists - it is intended as additional roll-away protection that complements (rather than replaces) the handbrake (which, as the name implies applies actual brakes - usually ...

It's used on front engine rear wheel drive and most 4 wheel drive vehicles it couples the transmission with the rear differential. Picture Source In the picture above you can see the driveshaft where it's connected to the pinion on the rear end. The drive shaft is the part on the lower right side of the picture. The other end of it would be connected to ...

Some things to check in order of likelihood- Check the battery connections are tight. A loose connection may prevent your car from starting, even when the lights, radio, etc., may seem to be working fine. The battery may not be fine. Lights are not high load,so having the lights work is not an indicator of how healthy your battery is Starter motor. Some ...
