Pressure in the motor building up, using straight water instead of anti freeze, or having a blown head gasket or cracked head would cause a freeze plug to blow out. Better take it to a mechanic and have them look at it.
No. Cause THEY ARE PLUG IN.
When you hum you blow out air to make the noise, but if you plug your nose, no air comes out and you cannot hum. It is possible to hum for a short time with your nose plugged, but you will be unable to do so for very long or at any volume.
Quite simply the weight of water directly above the plug in a bath is considerably more than the weight of water above the plug in say a hand basin. In addition, the surface area of the bath plug is greater than that of a conventional hand basin plug. Therefore, the column of water being moved by the removal of the bath plug would have a larger volume than that of the hand basin plug. Consequently, weighing more and therefore requiring a larger force to move the plug in an upward direction. If you find pulling the plug on a chain difficult, then you can always upgrade your bath plug chain combination for a rotary cable 'pop-up' bath waste mechanism. This should aid your comfort in attending to the bath water evacuation process.
no because you wouldn't want to plug something in to it would you e.g your telly the best conductors are usually metals
On a British plug it is the earth pin connected to the earth wire. This is safety feature to stop electric shock
A bad freeze plug will leak coolant and cause the engine to overheat.
no withou a freeze plug the water will escape the engine and cause it to over heat.
Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose
Anti-freeze is not doing its job and the water freezes in the block compressing to the point that free plug does it jobs and relieves the pressure.
It would depend on which freeze plug. Some are easy and some are not.
most likely cause is damaged threads on the head or plug the plug was not tightened to proper torque spec either too loose or too tight
Most likely reason is that it is rusted out. Improper coolant to water ratio can help freeze plugs rust from the inside, and wet weather will help it along on the outside.
It could be a freeze plug but it also is not uncommon for the intake manifold gasket to blow out and allow engine coolant to leak out.
Check the threads for the spark plug, Im betting it was either crossthreaded or not tightened enough and worked itself out.
My first diagnosis would be a blown freeze plug, check that and you may find your problem.
I think you would know if you needed a freeze out plug for you would be losing coolant & losing coolant would make your ride run hot.
If it is a freeze plug it would not have threads. Freeze Plugs are designed to pop out of the block should the water in the block freeze. This could not happen if the plug was threaded. Hope This Helped.
