Extensive harm occurs in an engine that runs in an overheated state for a prolonged flow of time. This is the reason most all vehicles are equipped with a heat gauge or with a sensor that warns the driver if the engine heat is too high. When an engine overheats, the vehicle needs to exist turned off immediately to avoid permanent damage.
Seals
Seals and gaskets simply are designed to withstand the heat generated in the normal operation of an engine. When the engine overheats, the seals begin to melt, dry out out or scissure -- all of which tin can crusade leaks. Valve stem seals, for instance, crack after an engine overheats. This leads to a multifariousness of oil-related problems, including increased emissions. Functioning also may be compromised if oil balance gathers on the spark plugs or around the intake valves.
Croaky Head Gasket
If the engine gets hot enough, it tin crevice the caput gasket. The oestrus in the engine causes metal to expand. This puts pressure on the head gasket, which is neatly fitted into place. Eventually, that force per unit area cracks the gasket. When this happens, water leaks into the cylinders of the engine, which causes damage to other parts. A cracked head gasket is time consuming to repair because the entire cylinder head needs to be removed to admission it.
Warped Cylinder Head
If the engine gets extremely hot or if the heat lasts for a long flow of time, information technology tin can warp the metallic of the cylinder head. This is more mutual on modern vehicles with aluminum cylinder heads because aluminum warps more hands than the iron used in older-model cars. A warped cylinder no longer properly seals to the block. The caput gasket somewhen fails in this situation if the trouble is not caught and remedied. The warped head alone causes ongoing problems with overheating, and the vehicle may not idle properly.
Serious Overheating
In one case an engine gets hot enough for the coolant to boil, a number of events may take identify, all of which might hateful the cease of the engine. If the coolant is boiling in the radiator, information technology may blow a hose off its clench, blow a pigsty in the side of the hose or crusade the radiator to explode. What's worse, in an engine this hot, the pistons might great. This damages the bore, which means a very expensive engine repair -- if it is repairable at all.
