I just heard this one:
You can clean your battery terminals and mostly any bolt or fastener with Coca-Cola. It works better if the drink was sitting outside for a considerable time (so it should not be bubbling and must be warm)I just heard this one:
You can clean your battery terminals and mostly any bolt or fastener with Coca-Cola. It works better if the drink was sitting outside for a considerable time (so it should not be bubbling and must be warm)I’ve been busy asking everybody I know about myths, and I got a few quite interesting. Some of them are not service/repair related. they’re likely fancy things:
- Due to the way their aerodynamics are engineered, If a supercar goes in reverse fast enough, it will fly.
- Doing a emission test will be better during a rain, this can be considered a way to cheat.
- To do some close turns on a FWD vehicle, you could try to slightly engage the handbrake (thus, wearing it a bit more) and going slow. It’s not a drift thing BTW.
- Downshifting to brake on FWD vehicles should in some instances do some harm to the transmission.
- Also, there’s no direct benefit of downshifting to brake on these as would be on RWD vehicles, because the braking force distribution.
- A proven one: during a thunderstorm, the safest place is inside the car… (this is where it comes interesting, a new addition to it) but, it doesn’t mean that the car will be ok, there’s a high chance to catch fire if the wheels are filled up with certain mixtures of air, or the fuse box/battery may probably explode if highly loaded. (likely unbeliveable from my point of view, but gotta post it)
- Using water and detergent instead of wiper fluid is valid, and sometimes preferable.
- The water coming from the A/C condenser could probably be distiled.
- Some technicians think that the rear drum brakes MUST spin EXACLY ONE TURN with the wheel installed to be considered as correctly adjusted.
- Few dumb (I want to call them not experienced, as I once was one, I respect them) people lift the car from the suspension arms. (gotta clarify, I’m not saying that lifting it from the joints is all bad, I’m saying lifting it from the middle part of the arm itself, not a mount point which will propably be strong enough.)
- This is one of my favourite ones, I even had done this (Not really car related): If you filter coolant using coffee machines filter, you’ll end with universal coolant, which you can use to fill Computer waterpumps. This also evidences that some coolants have a gooish thing, which stays sticked to the filter.
- You can install a heavy truck horn into a very small vehicle, say, a bike, but it will overload the battery.
- It is possible to clean a bit of the rusty stuff out of the cylinders by removing the spark plugs and cranking/turning the engine. Eric has done this a lot of times, and appears that this side effect exists. To even increase the cleaning, you can use ATF as stated by Eric once, but you’ll end up with a lot of white smoke for a while, and using too much will be a bad thing instead.

Such a sad story…
I bet that they have few clients, or that guy will be fired soon…
Something similar happened to me with my automatic transmission (was stuck in 3rd gear, the shift lock didn’t work and was doing the only avaliable shift (N to 3rd) very hard. I just bough 3 little fuses and it fixed everything. At one shop, the guys told me that they will dismount the entire transmission for a possible repacement (the cheapest ones cost around 250 bucks and the best ones for my car were about one grand) and I just invested like $3.00 for high quality 10A fuses and fixed it myself.Such a sad story…

If for some reason your radiator is profusingly leaking, you can lower or even eliminate the leak in a temporary manner by using an.. EGG?
Yes.. as you read. Eggs can stop a leak in a case of extreme emergency (NOT RECOMMENDED though) just enough so you can take your car to a repair garage to sawp the failing radiator or leaking hose. Note that the car must be on and hot, so the egg can cook into the leaks. It’s a very old trick, and it inspired current Stop Leak products.Guess what… I just heard the weirdest of all myths yet…

The pressure sensor was also misreading fuel gas pressure, and letting the tank fill up with it. so, sometimes, the gas escaped trhough the cap when refueling (stopping the gas station pump constantly). It will stay a bit there, because the guy has to make another cars, and finding that particular fault in the electrical systen will took a while.

[quote=”grimreap93″ post=72867]I’ve always heard that if you get two tires of different sizes on the rear, or front that it effects your speedometer, Is this true Eric? Thanks.[/quote]
Well, it might be…
I’m a computer systems engineer, and I can tell you that, according to the math related to RPM to m/s conversion, gear ratio as well as wheel size does matter (because wheel size is gear ratio too), because, as far as I know, the speedometer reads the revolutions per minute on a tire, or maybe just on the axle, or the output of the transmision, and then applies some simple math to get the speed, but it has no way to know what size the wheels are.
You can see it this way:
The speedometer thinks that for example, 4000 RPM on the output of the transmission is, for instance, 60 MPH.
At that RPM, the wheels of a determined size, let’s say, 17″ run at 60 MPH. (The maker suposes that you’ll use this size of wheel, because they specified it on the manual, and have engineered the car that way). Now, think of putting bigger tires, so, each tire revolution will actually move the vehicle further than with the smalles ones, so the speedometer will still read 60 MPH (or 4000 RPM) but the wheels, even if they spin at this velocity, will travel more. You can search on the internet for a PI number animation, and it will give you an idea of what’s happening.[quote=”grimreap93″ post=72867]I’ve always heard that if you get two tires of different sizes on the rear, or front that it effects your speedometer, Is this true Eric?

Think of it as with your AC compressor, or a supercharger. Now I use the N a lot more after that… Well, if my car were out the shop (EVAP related issues, I posted that somewhere else in the Forum)
