The logic behind replacing the coolant, rather than just topping it off, is to remove impurities. If the reason you have to add to it is that there is a slow leak somewhere, you may get by with just adding some now and then. But if the nature of the problem is that that coolant itself is being depleted, without removing any impurities, then yes, it has to ...

Is it magnetic? if so, a big magnet (from a speaker for example) might help...

To get to basics, the rod (or connecting rod) is the portion of the engine which connects the piston to the crankshaft. Where the rod connects to the crankshaft there is a bearing which separates the rod itself from the crank journal. The bearing is made from a softer material than the rod or the crankshaft. You can see most all of the internal parts of an ...

You shouldn't be constantly replenishing the coolant - if you are, there's probably something wrong with your car! Modern car cooling systems are designed to be almost maintenance free, so you should only need to drain and replace it after a long interval (e.g. the 11 years you quote), rather than every two years with older systems - obviously you should ...

You take 2 nuts and put them on the same set of threads. Then lock them against each other by loosening the lower nut and tightening the upper nut. Then use the upper nut with your torque wrench to install the stud.

Adding something to fuel tank: Not necessarily, just purchase good quality gasoline. It already has all the additives needed to protect the engine. However, I understand that in Brazil, fuel may contain quite a lot of ethanol. Do make sure your car can handle it. However, if you drive so little the gasoline becomes stale, you might want to consider some sort ...

There are so many different products you could go with for this. Only problem is the products are usually really hit-or-miss. When I finally found one that worked well I ordered as much of it as possible. Leather Magic, the name describes it perfectly. I used the delux kit a few times before ordering the pro kit. The delux kit sells for about $59.00 and it'...

There are silicate antifreezes, used in most domestic cars until recent years, and OAT antifreezes, used in Japanese cars because of their domestic market testing. In OAT antifreeze the silicate has been replaced with phosphates. Domestic cars today all use OAT now, with Chrysler the last to switch. See: http://www.sae.org/mags/aei/mater/11284 So any OAT ...

Yes, you can do an inspection and learn a lot about it's condition. If you're not familiar with what to check, it may be worth getting an expert to have a look over it (if it's a classic car, your local owner's club will often have plenty of enthusiastic members who would be happy to tell you what it needs) As a guide: Tyres - these will probably have ...

They need to be aligned Well, technically the wheels need to be aligned. This doesn't have much to do with fitting tires and is more of a mechanical maintenance item on the car. It's a good idea to have an alignment done when you buy new tires because poor alignment will make your tires wear out very fast. Since its a new car, if you drive on good roads ...

The main things I've always heard/done. Always unwind before storing. This helps to keep stress off the springs. If you leave it wound up, the springs can get weak and give inaccurate torque readings. Don't go past the click. Once it clicks, don't turn it further. Can't remember why you shouldn't do this (aside from over-torquing). I always try to ...

If the area you lost it in isn't too large, you could shovel the snow into a big bucket, bring it inside, and let it melt. This could be tricky if the area you might have lost it is large, or if the snow is deep. Any other way of melting the snow in place would also work if you have a portable source of heat. If you're in no rush, just wait until spring!

They will probably work out to be the same. An automatic transmission is inherently more complicated which means more can go wrong and usually does (more so than manuals). The increased complexity also makes them more expensive, heavier, less fuel efficient etc. A manual transmission is less complicated which means there is less that can go wrong. Through ...

When disconnecting a clamp from a car battery, there is a danger of creating a short circuit with the tools that are in contact with the battery terminal. So a tool in contact with the positive terminal can cause a short circuit if it touches any piece of grounded metal. Starting with the negative terminal removes this danger; now you only need to ensure ...

Caveat: this is your vehicle. Please consider our opinions as such and make the best decision that you can. Here is how I would group things without considering price. I'll try to be guided by your "about five more years" and your climate (assuming that NE Ohio is roughly equivalent to central Indiana <- where I spent six years of graduate school). ...

Here's a "tip to make sure I got everything right" for the future. One that I use myself, and taught my Auto Tech students as well: The very first thing is to take off the oil cap, and place it over the latch area for the hood, such that you can't close the hood unless you move the cap. This prevents the worst possible thing: finishing the job but ...

If the site of the tragedy is such that you can easily acquire water, use a hose (or a bucket) and simply run/pour water over the area to melt the snow. Since snow is an insulator, running a propane torch will be an exercise in patience (and an exercise in buying a bunch of propane). Water is cheap, melts snow faster, and is less likely to burn your house ...

Why rotate tires at all? You probably already know this, but the reason we rotate the tires is to even out the wear and to try to maximize the miles from each set. For that reason, if the vehicle has a full-size spare tire that is also the same size and is also non-directional, it would be included in the rotation. If the vehicle had dual rear wheels (as ...

Battery operated flashlights or worklights which share batteries with your cordless tools would be a good option. These will allow you to work on the car even with a dead or disconnected battery. Choosing the right tool will give you either an area light or a focused light. Examples from one manufacturer: Other major makers such as DeWalt and Milwaukee ...

There are two main things about tranny fluid: Transmission fluid is checked when it's hot (up to running temperature). As the fluid gets up to temperature it expands. If the fluid is cold, it won't give the proper level reading, thus overfilling will ensue. One of the main fluid compartments of the transmission is the torque converter. When full, the fluid ...

To the Mechanic suggesting 3000 mile changes, that recommendation has changed considerably. Several articles and studies have been done disproving the necessity of the 3k change. On any vehicle in the past 10 years, owners should follow their manufacturers suggested intervals which is usually 5k or closer to 7k for fully synthetic oils. I'd argue that it ...

There are a number of ways to do this, but the two that come immediately to mind are battery-powered LED work lights. (A quick internet search will turn up many). Two varieties might be of use/interest to you. Some can be powered by the vehicle's battery which is convenient unless you're doing something like replacing a flat battery. Others have their ...

Great question. My preference is silicone spray, as you suggested. I'm pretty sure this one is the one I usually get for this kind of job. Apparently I'm not the only person who thinks this is a good idea, either: Home Repair Central says, The two best choices are a silicone spray or white lithium grease. My preference it the silicone spray. It is ...

In the two pictures/icons you provide the arrow is intended to indicate the flow of air with regards to the cabin. Where the arrow is coming in from outside the car allows air from outside the vehicle in through the HVAC vents. The circular (ish) arrow indicates that the air already inside the cabin is being recycled through the HVAC system and put out the ...

This is normal behavior. The A/C system is turned on to dehumidify the air, which causes the windshield to defog. Without it, your breath would freeze on the inside of the windshield and cause further issues. EDIT: Please note Bob Cross' comments below. I found instructions on the Honda Tech Forum which is supposed to give you full manual control over ...

DISCLAIMER: This is one of those questions where you are going to get a ton of opinion and speculation, and my reply will have some of that in it as well. I think there is a lot of myth out there about what cars actually need to maintain them as they are and should be. For instance, your comment about the M5 owner. The entire statement is about seat of the ...

The only type of vehicle you need wait on is a diesel powered one. The reason for that is you need to wait (in most of them) for the glow plugs to heat the combustion chamber. Modern fuel injected cars will keep their fuel pressure after shutdown. It will stay there (usually) for a good 24 hours (Note: 24 hours is an approximation. It will take longer in ...
