  Hot weather has been known to affect a car's performance,
particularly its batteries, tires, radiators and air
conditioners. The heat causes the acid and fluid inside of
batteries to expand, which can lead to a leak and the potential
for failure. This could leave you stranded on the side of the
road, waiting for a tow truck in the hot weather.  Preventative
maintenance is the best way to avoid future repairs, that could
end up being more costly in the long the run. Be sure to take
your car to a local service shop to have your fluids checked.
Low coolant levels could end up destroying an engine, costing a
lot more than a simple service check. In addition, belts & hoses
stretch with age and in long periods of heat, eventually leading
to engine failure before you can shut it down.  While you are at
a service shop a mechanic can check your air conditioning, which
is often forced to work harder in the summer the months.
