2. Serpentine Belt History
• In 1985 when Mercedes-Benz used the
first serpentine belts, it was the beginning of
a revolutionary change in the engine belt
industry. Before the serpentine belt, thinner
belts were used. This was not optimum for
mechanical efficiency.

3. Serpentine Belt History
• The idea behind the serpentine belt is to use a
single, wider belt so that tension can be
increased. This increased tension helps reduce
slippage, wearing of the
belt, squealing, increases the belt life, and the
overall mechanical effectiveness. What that
means is your engine runs smarter, not harder.
There is less wear on the belts so they last
longer.

4. Serpentine Belts Save $$$
• But it gets even more economical than that.
Sure it saves you time and money on changing
out the old belts, but it also reduces engine
wear and tear and lowers your gasoline bill.
Who can’t appreciate some fuel savings
nowadays? Though you may not remember
the days of the pre-serpentine belts, you can
be thankful and appreciate fewer headaches
and a few dollars saved.

5. Serpentine Belts Are Also Known As
• There are a few other names for the
serpentine, though this is the most common. You
may hear them called multi-rib (because one side
is ribbed), poly-v, multi-v, or multi-vee. These all
mean the same thing. The way the serpentine is
designed to work is one continuous belt that is
used to connect your engines peripheral devices
(water pump, air conditioning
compressor, alternator, power steering
pump, and maybe some type of tensioner). This
is great because when it needs replaced you only
have to replace one.

6. Serpentine Belt Longevity
• You may never experience the need to replace
a serpentine belt because they last so long.
Often they will last over 50,000 miles. If
you’ve never had to worry about changing a
belt, you can be thankful the serpentine was
invented also. If we still used the old type of
belts, you would have had the experience of
replacing one.

7. Serpentine Belts Are Also Known As
• Anyway, as far as disadvantages go, there is
really only one, but it is a big one. If you
ignore a bad belt and let it break you will lose
all engine functionality. Nothing will run
without the serpentine because there’s no
way to turn the parts.
