Problems on the Road
4.
With the coolant surge tank pressure
cap off, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine
fan.
By this time, the coolant
level inside the coolant surge tank
may be lower. If the level is lower,
add more of the proper
mix
to the
coolant surge tank until the level
reaches FULL COLD.

Ifa Tire
Goes
Flat
It's unusual for a tire to "blow out"
while you're driving, especially if you
maintain your tires properly. If air goes
out of a tire, it's much more likely to
leak out slowly. But if you should ever
have a "blowout," here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the same correction you'd use in a skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.
Changing
a
Flat Tire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn on your hazard
warning flashers.
