Three Critical
Concerns for Confident Cold Weather Travel
All vehicles need attention from time to time, but
here in the wintertime your car needs extra care. For confident winter
starts, it is important to keep a watch on three critical areas: the
lubrication system, the cooling system and the battery. Let's take a
quick look under the hood to see if you're ready for the worst of Old
Man Winter.
Check Your Motor Oil
It is important to check your motor oil levels on a regular basis.
Without lubrication, friction between moving parts leads to engine
wear.
But it is also important to think about the type of
motor oil you are using. For severe cold, there is a significant
performance difference between synthetic and conventional motor oil.
Cold weather is tough on engines because of the
limitations of traditional lubricants. Motor oils and greases become
thicker, thus slowing starting rpm, restricting oil flow to critical
engine parts, increasing wear on bearings and rings, decreasing engine
life, and increasing the burden on an already overtaxed starting
system.
For really cold weather, only synthetic motor oils
offer the kind of performance that allows cars and trucks to start
with ease. Many synthetic motor oils still flow or pump at
temperatures up to sixty and seventy below zero. Synthetics have a
broader service range than traditional petroleum.
The admonition to check your motor oil is intended
as a reminder to not only watch fluid levels, but to consider whether
your motor oil is fulfilling its lubricating function in severe
weather. No sense in being stranded on an isolated road because your
engine couldn't turn over.
Check Your Antifreeze
Most of us who have grown up in this hostile region are aware that
inadequate antifreeze in the engine's cooling system can result in
serious damage to your vehicle. When water freezes it expands, putting
high stress on the corridors where it travels. A cracked engine block
is not unlikely in extreme cold. Water pump failure and blown hoses
are also common side effects from frozen cooling systems.
There are a number of relatively inexpensive
antifreeze testers available for measuring the effective working
temperature of your antifreeze. If you don't own one of these gauges,
be sure to have the radiator fluid checked at your local service
station to make sure it is suitable for severe cold temperatures.
In recent years there has been a growing awareness
of the hazards associated with traditional Ethylene Glycol antifreeze.
EG-based antifreeze is not only considered an environmental hazard and
deadly for pets when spilled on the ground, it is toxic for children.
What is especially bad is that Ethylene Glycol-based antifreeze has a
sweet taste that invites animals and children to ingest it.
An alternative to Ethylene Glycol antifreeze is the
new Propylene Glycol which is generally regarded as safe even in the
event of accidental ingestion. In addition, it has an unpleasant taste,
making it unlikely that animals or children will drink any appreciable
amount. Propylene Glycol provides excellent protection against
freezing, boiling and corrosion. In addition, the new AMSOIL Propylene
Glycol Antifreeze is compatible with all other antifreeze products and
does not require a complete system flush before usage.
Check Your Battery
The ideal operating temperature of your car battery is 80 degrees F.
As temperatures drop, so does the efficiency of the battery. In very
cold weather, the battery's power output can be diminished to as
little as ten percent.
What's more, as batteries age their strength is
further reduced. When it is very cold and your older battery has lost
a measure of its cranking capacity, you have a situation where it may
not have the power to turn over the engine.
Cold winter starts are harsh. If the motor oil is
not fluid, and the battery worn down, you may want to have your
cellular phone handy in case you need to call for help.
Be Prepared
It never hurts to be prepared, as the Boy Scouts are fond of saying.
Even when you follow these routine maintenance checks it is still wise
to stock the usual survival supplies as standard procedure for your
vehicle - shovel, bag of sand or grit, toolbox, jumper cables, fuel
de-icer additive, large flashlight and road flares. Extra blankets,
clothes, food, fluids and a first aid kit are a life insurance policy
that you hope you won't ever need, but sometimes can't afford to be
without.
Good snow tires, and a few seasons of experience
driving on slippery roads also helps...and knowing when not to attempt
driving at all. |
