Not a good idea, you may and probably will crack and warp vital parts. Let it cool down on its own before even adding cold coolant into the system.
1. overheating 2. temperature of engine not coming up in winter 3. poor engine performance 4. low gas milage
check and see if your thermostat is stuck open(top of engine block). depending where you live, water could be slushy or frozen in your engine.
If it blows in the right place. The exhaust is getting into the water passage which will cause the car to overheat. Probably in just a few minutes. With the engine cold, take the radiator cap off, make sure it is full. start the car. If the head gasket is blown, water will shoot out the cap for a foot or two.
If I understand your question properly I think you're referring to the engine timing. (when the spark plugs fire in relation to the rotation of the engine) When the temperature sensors on the car sense the engine is cold it will advance the timing of the engine to keep it from stalling out.
True... warm water is less dense than cold water.
Most definitely.
Pouring cold water on an overheated engine can cause rapid cooling, which may lead to thermal shock and potentially crack engine components, such as the cylinder head or block. This sudden temperature change can damage gaskets and seals, leading to leaks. Instead of using cold water, it's advisable to let the engine cool gradually or to use coolant if necessary.
intake manifold gasket,head gasket,cracked head,cracked block. was it overheated? was cold water added to hot engine?
No. Hot or cold. This can be done by running the engine at the same time to ensure the fluid mixes. The danger would be introducing cold water into a hot engine which could crack the block.
Pouring cold water on a heated engine can cause thermal shock, which may lead to the engine block cracking or other components becoming damaged due to the sudden temperature change. It is important to allow the engine to cool down naturally before adding any water.
Have you checked your thermostat?
No. Let it cool down before you open the radiator cap and then put water in the radiator
Cold. If magnets get overheated, they can cease to work all-together.
pouring a bucket of ice-cold water on him/her always works
It is a physical change. The wax simply hardens in the cold water. You still have wax and you still have water; nothing new has been formed.
Yes, it is possible for a glass tumbler containing hot water to crack if you cool it rapidly by pouring cold water on it. The sudden change in temperature can create stress within the glass, causing it to crack or shatter. It is recommended to gradually cool the glass to prevent this from happening.
there can be several reasons, however it is usually due to overheating and/or sudden cooling --- such as overheating the engine and then pouring cold water into the radiator, etc. Occasionally, the engine manufacturer may have a flaw in the head casting or too thin metal, etc that will cause it to crack too.
