The 3 Most Common Engine Problems March 18, 2013 Regardless of age, mileage,
make, or model, occasional engine problems are an inevitable part of car
ownership ds708
update cost. While proper maintenance may help reduce the need for car
repairs it is not a guarantee that a car will not break down. As a car
accumulates miles the chances of engine problems increase; however, not all
engine problems are serious. Many times the cause is something as simple as a
dirty air filter or loose gas cap. Engine Won't Start A no-start condition is
one of the most frequently encountered engine problems. If there is a clicking
noise but the engine does not crank it generally indicates a battery issue. An
engine that cranks but will not start is indicative of a fuel or ignition
problem. Common reasons an engine won't start: > Low or discharged battery
> Corroded or loose battery cables > Starter motor relay failure >
Ignition switch failure > Defective fuel pump > Clogged fuel filter
Service Engine Soon Light The Service Engine Soon light is designed to
illuminate whenever a fault is detected in any of the sensors attached to the
emission, engine, or powertrain controls. The purpose of the service engine soon
light is to alert the driver to a potentially serious fault that requires
repair. Blue exhaust smoke along with the service engine soon light may indicate
a fuel system fault caused by an engine oil leak. An ASE certified mechanic can
retrieve the trouble codes from within the onboard electronic control module and
determine the specific cause. Frequent service engine soon light causes: >
Loose or missing gas cap > Spark plugs or wires that are worn out or damaged
> Electronic control module failure > Defective distributor or coil packs
> Emissions control fault such as the oxygen sensor > Fuel quality issue
Overheating Overheating is most generally caused by a low coolant level. A quick
check of the coolant overflow reservoir will indicate if coolant is leaking.
Most cars are equipped with temperature gauges or warning lights that will alert
the driver to an overheating issue. Frequent overheating can cause serious and
expensive engine damage. Proper maintenance of the cooling system is vital in
order to maintain the quality of the coolant and to make certain the cooling
system is in good operating condition ds708

cause overheating, coolant loss and white exhaust smoke, which may indicate the
need for engine repair. Common reasons for overheating: > Faulty thermostat
> Dirty or low coolant level > Non-functioning cooling fan > Kinked or
broken radiator hose > Internal or external coolant leak > Defective
radiator cap > Dirty air filter Following the manufacturer's maintenance
schedule is very important. Services such as oil changes, oil and fuel filter
replacement, and tune-ups are necessary in order to keep a car performing at
peak condition. Maintenance items, such as the air filter, are often times
overlooked but can have a significant effect on a car's drivability and
performance. Regardless of a car's age, proper maintenance will help prevent
potential engine problems and break downs.
