There are two common types of gauge mechanism - magnetic gauges and bimetallic gauges. You can tell which type your car has by the way it reacts when you switch on the ignition . With magnetic instruments the needle immediately jumps to give a reading; bi-metallic gauges move slowly to the reading after being switched on.
Using diesel fuel in a gasoline vehicle is definitely possible, but it won't make your engine run any better. In fact, it will usually clog up your filters and might even damage the pump on your car or truck. Diesel engines need diesel fuel to operate at peak efficiency; if there's no filter separating the two types of fuels, then you'll end up with some major problems that can cost a lot of money to fix. Using the right fuel is especially important if you own a diesel vehicle that has an emission system- using the wrong kind of fuel might cause damage to the engine that will lead to it being unable to pass inspection.

Initially, the oil leakage will be minimal, getting worse as time goes on. After some time, it could even coat the valve cover surface, causing a thick layer of dirt to also accumulate on the valve cover.
Just as it is important to prepare for fires in your personal vehicle, itвЂ™s important to prepare for fires in commercial/industrial vehicles and machinery. Vehicle fire suppression systems can detect and suppress fires before they have a chance to do severe damage to your equipment. These systems protect the operator from severe or fatal injuries, prevent downtime and save equipment.

Wrong fuel in the gas tank, this happened with many people. DonвЂ™t start the engine if you notice during or after filling up the gas tank with the wrong fuel. If you start the car engine with the wrong fuel, you and your car could be at risk.
Buy an aerosol can of dry Teflon spray. It sprays on as a liquid but dries to a white slippery Teflon powder. Shake the can vigorously to mix the Teflon particles with the solvent. Insert the straw into the nozzle and aim the spray into the window channels. Press the trigger and soak the front and rear channels until the spray runs down into the door. Wait a few minutes for the solvent to evaporate, then operate the window up and down several times to spread the dry Teflon spray through the channels.

Maintain the radiator and cooling system by regularly flushing and refilling the coolant. Ensure that the thermostat is functioning correctly to regulate engine temperature. Additionally, consider using a coolant mixture with the appropriate water ratio to coolant to prevent overheating. If you notice any leaks or unusual smells coming from your vehicle, it may be a sign of a cooling system issue that should be addressed promptly.
This is a very rare issue, but it can absolutely happen! Oil has several properties, but one of the critical ones is cooling. Without enough oil, engine components will create a lot more friction, which heats everything.

Step 5: Manufacturing and Production.
The chain of reactions which achieve that objective is set in motion by a spark , which ignites a mixture of petrol vapour and compressed air inside a momentarily sealed cylinder and causes it to burn rapidly. That is why the machine is called an internal combustion engine . As the mixture burns it expands, providing power to drive the car.

Sounds like: Well, like something going tick tick tick This is an annoying noise, and one that could mean big bills if you ignore it. If you get a ticking noise, normally from the front of the car, thereвЂ™s a good chance it means your constant velocity (CV) joint is worn. Normally packed with greased and protected from the elements by a rubber вЂbootвЂ™, the CV joint is a crucial part of driving your wheels. If youвЂ™re getting a ticking noise, it means itвЂ™s worn out. A worn out CV joint will get hot, it will get progressively weaker and eventually, it will break, leaving you stranded in the process. Most garages can have a look and fit a replacement if needed, though be warned, it can be costly as it requires the removal of the brakes, wheel hub and even suspension parts in some cases.

Of all the car problems you might encounter, a squealing belt is potentially the most annoying. When the rubber belt loses its grip and slips around the pulleys it produces a high-pitched squeal. In rare cases, a worn slow-moving alternator, pump or AC compressor bearing or component misalignment can cause even a perfectly good belt to squeal. But most of the time the belt slips because itвЂ™s either worn down, is too loose or has been contaminated with oil or coolant. You can diagnose all those problems yourself with a visual inspection, a belt wear gauge and a spray water bottle.

The primary purpose of coolant is to cool down your engine. So, itвЂ™s no surprise that if your vehicle is low or out of coolant, your engine will overheat! Just keep in mind that your vehicle has a sealed cooling system, so if youвЂ™re constantly adding coolant, you need to figure out where itвЂ™s going.

Urine in a gas tank depends on how much urine is in the gas tank. A small amount of urine in a gas tank is not going to damage anything. The small amount of urine is like pouring a glass of water. But huge amounts of urine are obviously bad for gas tanks.

If either of these occurs, donвЂ™t panic. Your car will return to normal once the cleaner and residue burn away.
Although you might know that synthetic oils outperform conventional oils, you might not understand why. The differences begin at the molecular level.
6. Malfunctioning Computer.
Your vehicleвЂ™s cooling system relies on a thermostat near the engine to determine when to send out coolant to regulate the engineвЂ™s heat. So, if you have a malfunctioning thermostat, the entire system can be thrown out of balance. If the thermostat fails to detect high temperatures, it will hold up the flow of coolant, and your engine will overheat. On the flip side, if the thermostat has failed and is allowing coolant to flow constantly, your engine will have a hard time getting to operating temperature. The best way to avoid this is with regular cooling system maintenance, including coolant fluid exchanges as per manufacturer recommendations.

Oversteer is when the momentum of a turning car breaks its back tiresвЂ™ traction and is visibly seen when the rear of your car rotates toward the front of your car. The most illustrative example of this is drifting, which is when a driver initiates oversteer to drift/slide the car around the apex of a corner and continue moving forward.
Even if you're parked on a level surface, there's really no reason not to use the parking brake . Not engaging the parking brake puts the entire weight of your vehicle on a little piece of metal in the transmission called the parking pawl . It's only about as big as your finger, so it can wear out or break eventually from holding all that weight . Using the parking brake evens the load, helping delicate transmission components last longer.

Depending on where you live, flash flooding might be an issue you see from time to time and some day you could face a situation where driving through high water is unavoidable. Even six inches of water can reach the bottom of passenger vehicles and if that happens it can set off a chain reaction of devastating damage to your engine. Water close to one foot deep can float cars and two feet of water can sweep away most vehicles, not to mention road visibility disappears when thereвЂ™s flooding, which can lead vehicles off the road.
The tachometer is labeled with single-digit numbers. It usually starts at 1 and goes up from there. If the gauge reads 3, this indicates that the RPMs are 3,000. All numbers are multiplied by 1,000 to get the revolutions per minute rating.

TheyвЂ™re compact, powerful and they make an awesome noise. So why did rotary engines never really take off, and why has the concept been all but abandoned by the one manufacturer that championed it? LetвЂ™s take you through it. The 1964 NSU Spider was the first production car in the world to melt the rear tyres under the power of a Wankel rotary engine. The WankelвЂ™s automotive debut was decades in the making, though its lifespan was relatively short ending with the 2011 Mazda RX-8. This leads us to several questions:
Suggested by Aris Mone.
Nissan Leaf Plus battery Photo by Nissan An EVвЂ™s traction battery вЂ“ the big one that powers the electric motors to turn the wheels вЂ“ generally prefers to be somewhere between about 15 to 25 degrees Celsius. At lower ambient temperatures, the battery wonвЂ™t provide as much power, and the vehicleвЂ™s range can drop as much as 20 per cent when temperatures outside are below freezing. If the battery gets too hot, it will initially lose some of its power. If its internal temperature continues to rise, it can potentially degrade, suffer partial damage, or experience complete failure, including catching fire.
While the RPMs are low, such as when youвЂ™re idling or moving slowly, only a small amount of water may enter. In this case, you need to act swiftly to remove it before it causes corrosion issues.
In this guide, I evaluate the RPMs in depth. I show you the symptoms of idle speed problems and give you some ideas of what might fix it.
