50% water, and 50% antifreeze, winter and summer. Depending where you live if you're in a hot climate like Arizona. You can do a 30% antifreeze and 70% water. But always make sure you use the correct type of coolant that the manufacturer recommends
The Automotive Water Pump In general the main purpose of the automotive water pump is to circulate the coolant of the cooling system of a water-cooled engine.
anti-freeze is recommended for use in the cooling system
3, 5, 10 years. It depends on the type of coolant used.
An pressurized automotive cooling system containing a 50/50 coolant/water mixture will boil at 236 degrees F.
to increase the waters boiling point
Yes, but it is not recommended to run straight water in the cooling system.
Putting non dexcool compatible coolant in the cooling system can cause problems and sludgy buildup in the cooling system but Most coolant you buy these days will say on the bottle "compatible with any colour coolant " or compatible with dexcool" and if it doesn't you can easily find a brand that will be compatible with dexcool coolant at any automotive store. If you have allready mixed the coolant with non compatible coolant I recommend to flush ur coolant system and use a dexcool compatible replacement coolant flushing the coolant system every few years is a good practice even if you have 5 year life coolant..
As long as your reservoir has an overfill or overflow tube attached to it you can fill the radiator and the block itself with coolant and it will not hurt a thing.
Unless there are big stickers saying otherwise, any vehicle will use ethelyne glycol based anti-freeze/boil-over protection coolant, such as Prestone, Prime, et cetera. Just beware of the 'really cheap' coolant, which is a 50/50 mix of coolant and water. Such is what you are supposed to add to the cooling system, but knowing how to drain the block is beyond most people, and, without draining the block, getting proper concentration in the cooling system using a 50/50 mix can be difficult. I recommend buying undiluted coolant, pouring out about a quart, and adding a quart of water to the jug, mixing well, and then adding to the cooling system. (Of course, this is after the cooling system has been properly back flushed to clean out sludge and corrosion.) Do not pour undiluted coolant into the cooling system, as it can corrode portions thereof before it mixes with the water in the cooling system. Do not run undiluted coolant in the cooling system, for the same reason. A 50/50 mix will protect a cooling system to about -45 degrees Fahrenheit, and if if gets colder than that where you live, you should be aware of the extra precautions you should take, such as block heaters, oil heaters, et cetera. It is necessary to have water in the cooling system for it to work properly, the anti-freeze is there to keep the water from freezing, not to act as a coolant on its own.
Radiator-- for storing and removing heat from the coolant. Pump-- used to circulate coolant throughout the engine and back to the radiator for cooling. Fan, either electric or mechanical -- used to draw air through the radiator thus removing heat. Thermostat--Used to keep the coolant at a set temperature. Radiator pressure cap--Used to keep the pressure at a set amount in the system. Hoses uses to transfer coolant from the radiator to the engine and back. Recovery tank--Used to catch any coolant that may overflow.
There is little difference between the various brands of commercial automotive coolant on the market. Prestone may make this claim, and Zerex may make that one. The bottom line is that the Society of Automotive Engineers and the auto makers themselves have minimum requirements for auto coolant. And surprise! all the coolant manufacturers make coolant that conforms to at least the minimum standards. If in doubt, call your BMW dealer, ask for the service department, and inquire about what they recommend. It is far and away more important the the cooling system be serviced and maintained properly (and regularly!) than it is to find a "perfect" coolant.
