Always use antifreeze. Water does not have any water pump lubricants or anti corrosion properties, antifreeze coolant does.
Yes and no. It can depend on the condition of the coolant and type of antifreeze used. Some vehicle engines produce more rusts and corrosion than others. Some types of antifreeze are rated for a longer use than a regular maintenance schedule. Sometimes it is better to replace coolant with a new mix before a regular maintenance schedule. (Distilled water is suggested to be used for an antifreeze mix, use of tap water can potentially degrade the performance of an anti-freeze mix sooner )
The use in modern engines is not recommended because of the high temperatures encountered by the coolant. Etylene glycol or other antifreeze products also raise the boiling point of the water, to better avoid overheating.
No, regular antifreeze designed for cars should not be used in motorcycles. Motorcycle cooling systems often require specific types of coolant that are formulated to handle higher operating temperatures and provide better protection for the engine and its components. Always check the owner's manual or consult the manufacturer for the appropriate type of coolant recommended for your motorcycle.
The typical coolant mixture ratio for a Renault Scenic is usually about 50% antifreeze and 50% water. However, in colder climates, the ratio might be adjusted to 60% antifreeze to 40% water for better protection against freezing. Always refer to the vehicle's owner manual for specific recommendations.
You make sure to let it thaw out before you drive it. The real risk is that it won't thaw out, then, when the thermostat opens, there'll be nothing to go through and cool the engine down. Water is actually a better coolant and has better heat transfer properties.. however, it doesn't function well as an antifreeze, and also lacks the necessary lubricants for the water pump. You should probably go get a coolant flush done and get proper coolant that's rated to -34.
More than likely it takes less than a gallon,...of antifreeze. It WILL hold more coolant than that however...remember it's a mixture....better still go to a mechanic and have him do a drain and fill.....that way you get it (the mix) right.
On a 2003 Ford Explorer Sport Trac, the temperature coolant sensor is typically located near the thermostat housing, which is situated on the engine block. It can be found on the driver's side of the engine, usually towards the rear, and is inserted into the engine coolant passage. To access it, you may need to remove some components or hoses for better visibility and reach.
Dex-Cool and green antifreeze serve similar purposes but have different chemistries. Dex-Cool is an organic acid technology (OAT) coolant, designed for longer life and better corrosion protection in aluminum engines, whereas green antifreeze is typically an inorganic additive technology (IAT) that may require more frequent changes. The choice between them depends on your vehicle's specifications and manufacturer recommendations. Overall, neither is inherently better; it depends on the application and maintenance practices.
Look carefully around your engine bay and identify parts. The windshield washer, oil, trans, and coolant lids are almost always marked on top. You put the antifreeze in the radiator or coolant overflow bottle. You often have to drain or remove some water first. - Better yet, get a manual for your car so you can understand it and do simple maintenance.
During the summer your engine would actually run hotter because antifreeze has a lower specific heat than does water. (That means a pure antifreeze solution will act as a better insulator than water---less heat will be transferred through the pure antifreeze solution.) Even during the winter, a 100 percent antifreeze solution isn't a good idea. A pure antifreeze solution actually provides less protection against freezing than does a mix solution.
If an engine has no water or antifreeze in it, it is better off than an engine without the proper anitfreeze to water ratio. You can buy a tester to determine the actual low temperature the water/coolant is safe down to. If the vehicle is not running and it only has water in it, cut the lower hose and let the water drain out and this will prevent the engine from freezing up and possibly busting the block or popping out the freeze plugs. If it has coolant in it you can drain the coolant and recycle or dispose of it properly according to local regulations.
