Overheating, caused by loss of coolant
or over pressure, can damage
Older cars can be particularly prone
to overheating, but this is largely
the result of inadequate maintenance
rather than a production failing.
Fans, hoses, belts, the radiator and
water pump all need regular attention to
ensure they are in tact and functioning
As soon as you notice that your
temperature gauge is running a bit
higher than usual, take the time to
inspect your engine and address

The Head Gasket:
A blown head gasket causes coolant
leaks, and you will find coolant in
your oil, or oil in your coolant.
Your engine will overheat if this problem
persists, so keep an eye on your fluids
to catch this problem as it occurs.
Your thermostat controls the movement
of coolant through the engine,
keeping it out when the engine is
cool and allowing it to flow as the
engine heats up.
If the thermostat fails, and coolant
doesn’t run into a heating engine,
the car will overheat very quickly.
If you haven’t found any problems with
the belts and hoses or the radiator,
it may be time to replace your thermostat.
Check the Timing and
Adjust the Carburetor:
Make sure these are adjusted to suit the
specifications of the manufacturer.
While these are not part of the engine’s
cooling system, problems with engine
timing and the carburetor can be a
cause of overheating.
Clean off dirt and bugs from the
Check for any leaks, which will
manifest as green or white deposits
on tubes or the tank.
You can weld these cracks rather
than use radiator sealant, which can
itself lead to more problems by
interfering with water flow.
Also make sure that your radiator cap
washer is being replaced from
time to time.
Check for inner blockages by
disconnecting the lower hose and
running water into the top, the water
should run out of the radiator at
the same speed that you are
pouring it in.
If not, back flush the radiator
to unblock inner cooling tube.
You may need to do this a few
times to clear everything out.
