Why must only a premixed coolant be added to a rally car engine?

so that its up to temperature quicker and therefore can activate drs

Do you add fluid when car is started or not?

That depends on the fluid being added: Automatic Transmission Fluid (ATF) should be checked after the engine/transmission are warm (has been driven several miles) and fluid can be added while the engine is running. After new fluid is added, the trans should be shifted through all the gears (Park - Reverse - Neutral - Drive - 2nd - 1st - 2nd - Drive - Neutral - Reverse - Park) stopping for a moment in each gear to allow the transmission to get 'in' to the gear, and placed back in Park before rechecking. Oil should be added without car running, then started and run for a few seconds, turned off and recheck. Antifreeze should be added to a cold engine, and can be added when you first turn car on, but after the thermostat opens (warm/hot engine) the level will drop and you can overfill it (excess will run out of the reservoir when it cools back off due to pressure it creates). Antifreeze is typically added to the reservoir to the indicators on bottle. Manual Transmission Fluid does not require engine to be on or off. All other engine fluids (Brake, Power Steering) should be added with engine off. Windshield washer fluid can be added at any time. Hope this helps...

When to use brake lights on the car?

When you feel the need to slow down or stop... Brake lights are universally required to be used on all public roadways throughout the modern world. Many countries have adapted the 'Third' or center brake light for added visibility.

When approaching a railroad grade crossing with no warning system you should?

Approach it slow and look both directions, stop first if there is a stop sign. * Added - Each state has different requirements in the US. In many states, the motorist is required to stop at the crossing and proceed only when safe to do so.

What is the difference between jet fuel and car fuel?

Gasoline Versus Jet Fuel For the first few decades of flight, aircraft engines used the same kind of gasoline as automobiles. As airplane engines became more powerful, however, gasoline wasn't the best choice. Most gas in the early 1900s had octane ratings of 87 or less. While that was enough for a car to work, airplane engines needed a higher octane grade. Fuel is rated according to its level of octane. The octane rating of gasoline tells how much the fuel can be compressed by the cylinders before it ignites. The higher the octane, the more compression it can handle before igniting. Higher octane levels allow engines to burn fuel more efficiently, rather than "knock," which indicates engine strain and potential damage. Merely increasing the octane wasn't enough for efficient flight, though. High-octane gas has a low flashpoint-the temperature at which it can catch fire by an open flame. Gasoline's flashpoint is around -1 degrees Celsius [°C] (30 degrees Fahrenheit [°F]). Aviators wanted a fuel that would be safer. At first, aviators used a mixture of kerosene and gasoline. It was called Jet Propellant 1 (JP-1), but a drawback was the way it smoked as it burned. Aircraft then went to using Jet-A commercial jet fuel. It is kerosene-based and has a flashpoint of 49 °C (100 °F). It's a high-quality fuel that includes an anti-freeze to prevent ice buildup inside fuel tanks. Jet A-1 is used by most turbine-powered aircraft. It's quite similar, but it has a higher freezing point. (Only the military and outside of the US is antifreeze added to jet fuel). In the US there are absolutely no additives in Jet fuel, also it's not made "from" kerosene. It's close to the same distillation, but they are different fuels. Airplanes can still use leaded gasoline, and octane ratings of 115 are seen in high-performance airplane engines. Jet engines, however, burn kerosene-based jet fuel. Just as automobile drivers are concerned with fuel efficiency and engine condition, airplane and jet pilots are concerned about using the best fuel for their type of aircraft engines.

New engine in storage does it require antifreeze?

If it has never had any water/coolant added, then no it doesn't require antifreeze.

Where do you put antifreeze in your 2005 Honda Civic?

Antifreeze is added to a 2005 Honda Civic at the coolant overflow tank. Antifreeze is added at a ratio of 50/50 with water for optimal cooling.

Is antifreeze added to car radiators to lower the freezing point of water?

Yes. The antifreeze/coolant also raises the boiling point and has lubricant and anti corrosive properties.

Can you put antifreeze in cars from 2000 2004?

In countries which have a winter season ALL cars should have the correct amount of antifreeze added to their coolant fluids. If this is not added and the fluid freezes the expansion of the ice will crack the engine block.

What can you do if you have already added the green antifreeze?

It depends on which antifreeze/coolant you used. The prestone brand claims it can be mixed with any other brand. Read the bottle to see if it has the same claim

Where does the antifreeze go for a 95 Plymouth Voyager?

To put in more antifreeze in a 1995 Plymouth Voyager, located the reservoir near the radiator. Antifreeze is no longer added directly to the radiator. It is put into the plastic reservoir that is labeled radiator or coolant overflow.

Where is the coolant port on Pontiac Aztek?

Not sure what you mean by coolant port... Antifreeze can be added to the cap on the passenger side of the radiator if it is low and the reservoir on the driver's side should be filled to the line when cool

What are the substances found in engine coolant?

Engine coolant is a chemical compound. It consists mainly of water, but water freezes too easily so an antifreeze is added. This helps prevent the coolant from freezing on winter days and it also raises the boiling point which is helpful. An antifreeze contains mainly ethylene, but also has some methanol and propylene. The water and antifreeze make up around 90% of the coolant. The rest of it is chemicals to prevent rust and corrosion (redox reactions) occurring. In other words... Coolant contains: Water - 60% Antifreeze - 30% Others - 10% hope this helps

Do you need antifreeze to drive your car?

No, but antifreeze has corrosion inhibitors in it's formula. These help to stop corrosion forming internally, and will also protect the head gasket from corroding. Antifreeze added to the water in your cooling system lowers the freezing point of the coolant, preventing the liquid from freezing in the cold winter. It also raises the boiling point of the coolant. If you drive your car with water and no antifreeze, your car will heat up and the water will get hot enough to boil over. With antifreeze, the coolant will continue to do its job of keeping the engine from overheating which can result in damage to the engine.

What Ratio of water and antifreeze is needed to keep water from freezing?

Coolant container will say if it is pre-mixed or full strength. If full strenght, mix it 50/50 with water. Pre-mixed coolant can be added "as-is"

What engine coolant to use in 1997 F-250 Powerstroke?

today's antifreeze is very much standardized. you go to any auto supplier buy the antifreeze which is on sale and follow the instruction will give you a new fill of antifreeze. WRONG! The following is quoted from Geno's Garage Tutorial: The coolant requirements of Diesel engines are not the same as those of a typical gasoline-powered engine. The correct coolant for your Power Stroke Diesel is an ethylene glycol (EG) type antifreeze. Ford Premium Coolant is one appropriate ethylene glycol coolant. If you have to substitute use a coolant with Coolant Specifications: ESE-M97B44-AAlso: Coolant for your Power Stroke Diesel needs to be more than just ethylene glycol based. The coolants marketed to the general automotive world are blended with a higher concentration of silicates (for dissimilar metal protection). Antifreeze formulated specifically for Diesel engines should be a low-silicate type. Unquote Each time you buy a gallon of antifreeze you also need to buy a gallon of distilled water. Water that has minerals in it, or hard-water, should not be used because the minerals will lower the boiling point and increase corrosion in the system. To prevent corrision, I use distilled water in everything in my vehicle that requires water to be added. Battery, windheild washers, etc. You can usally buy it at Walmarts for fifty cents a gallon.

Is antifreeze needed for heating system in car?

Coolant, usually referred to as "antifreeze," protects the engine as pure water cannot. Added to water, the coolant raises the boiling point, lowers the freezing point, protects against corrosion and lubricates the water pump. In a pinch, you can run the engine on water but you will get the best service from your engine if you keep a good charge of coolant in the cooling system.
