There is rust present.
rust occures by puting it in vinegar water
Iron will begin to rust after exposure to water. The reaction that happens to cause rust is due to the iron oxidizing.
they can barely rust and that is in water
tap water will rust it faster. tap water lets more oxygen get to the nail and should cause it to rust in a few hours after being put in the water
will objects rust more quickly in salt water or plain water without salt
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.
