The thermostat is under the housing where the upper radiator hose attaches to the engine.
The iron become overheated and can destroy sensible materials.
The device that controls engine temperature is called a thermostat and it's usually located where the upper radiator hose connects to the engine.
No real way of knowing for sure. I've seen them last for the reasonable lifespan of the vehicle, and I've seen them fail in a substantially shorter period of time. Lots of factors go into this, and there isn't a concrete answer to give here.
A thermostat on the wall measures air temperature to control a gas or electric heating (or air conditioning) system.
A thermostat in a clothes iron measures the temperature of the metal ironing plate to control the electrical heating element in the clothes iron.
I'm not sure what you mean by direction? The thermostat goes in with the spring side in the housing with the metal cross bar horizontally positioned.
You want a liquid that is not compressible so polar compounds are preferres. For safety, the nontoxic and highly stable silicones are used. They have low vapor pressures and high boiling points so they remain liquid and are quite noncompressible.
This type of thermostat is filled with Alcohol, which responds well to changes in airconditioned space.
Overheating can warp and crack cylinder heads, head gaskets and all bearings, especially crank bearings. In extreme it will destroy the engine
A thermostat is not a switch it is a temperature gauge. It is powered all the time by the electronics in which it is being used.
