Rust-colored water in the radiator typically indicates the presence of rust or corrosion within the cooling system. This can be caused by old coolant, lack of maintenance, or the presence of air or contaminants in the system. It is important to flush the system and potentially replace the coolant to prevent damage to the engine.
The gas that forms rust with water and iron is oxygen. Rust is formed when iron reacts with oxygen and water in a process called oxidation.
Rust is not toxic but it is disagreeable.
rust oxidizes when exposed to water
The cause of iron rust is oxygen and water.
Rust forms anywhere iron and oxygen meet with the presence of water
Rust is a noun. However, when used with an object it is a verb (to make rust coloured). It can be an adjective (having the rust colour).
Too much water/contains rust. need a flush & fill.
Water should be fine, but mix it with coolant when you can to prevent rust from developing in the radiator.
some cooling systems, you can check by removing the radiator cap when the water is cool. Then crank the vehicle and let it run until it reaches operating temp. If the water reaches or exceeds operating temp with no flow seen inside of the radiator, it could possible mean that your cooling system is clogged. Also a good indication is if there is rust deposits around the filler neck on the radiator.
Yes because it breaks down eventually & no longer inhibits rust. You can test water inside with a hydrometer, usually in radiator supply section.
Yes,
The cast iron in the block is starting to rust. Drain the radiator, put in a good radiator flush solution and follow the directions, then fill the radiator with the right coolant. Since you're already having rust problems, put in some rust inhibitor. You may need to clean it again and put in more rust inhibitor after things settle down.
I believe you mean into the radiator tank. Hopefully you also mean antifreeze and not just water. The engine has hollow passages around the hottest parts of the motor and the liquid absorbs the heat and flows through the radiator and cools down again. The reason we use antifreeze now instead of just straight water is because the antifreeze raises the boiling point of the water so the engine can get hotter without overheating and it also has anti rusting chemicals to keep rust from the motor from plugging the radiator core.
Using straight water in place of coolant will increase the chance of rust occuring within the cooling system and clogging up the radiator. Depending on the climate you live in, you will risk the possiblity of the engine freezing and cracking the block.
red water, i can think of two possabilities, rust,but that would not be exactly red. 2 a leak in your transmission cooler that runs through the bottom of the radiator. transmission fluid is usually red. a leak here would get into your cooling system.
mold or rust
Never put just straight water in your motor. You want to top off your radiator first then top off your coolant in the reservoir. Water will rust your motor from the inside out.
