Why does a car engine overheat?
|

There are many different reasons that can
cause an engine overheat, but they all have in common three aspects.
The three aspects which all engine overheat factors have in common are
that they cause that the heating system can not get rid of heat, they
cause a loss of coolant or they directly cause too much heat in the
engine.
One first problem which might be the cause of an engine overheat is a
problem with the radiator cap and the pressure it holds. If the
radiator cap does not hold pressure correctly then coolant could boil
and therefore the engine would overheat. Another reason might be caused
by thermostat failures; it is recommendable that you check it.
The car engine might also overheat due to coolant leaks such as those
from the radiator, the hoses, the water pump, the freeze plugs or any
others. Also, problems in the water pump could be the cause and
therefore you should check it and replace it in case it is needed.
Some other reasons by which the car engine could overheat are problems
in the exhaust system which you can discover by checking vacuum
readings, pipes and converter. Besides, you should also make sure that
the radiator hose has not collapsed and the ignition timing is working
properly.
You should also check the electric cooling fan by making sure that the
fan motor, the relay and temperature are correct or otherwise it could
cause the engine to overheat. Besides this, you should also check the
radiator in case there are any debris in it as well as you should check
its hose in case it has collapsed.
It is also recommendable that you check the antifreeze concentration
which should be 50/50 in order to be correct, otherwise it could cause
the car engine to overheat. If you do not find why your engine does
overheat, you should ask a mechanic or an expert for advice. You should
not try to fix this if you do not have the proper tools and general car
knowledge necessary for it.
