3. After the engine cools, open the
coolant air bleed valve or valves.
3.1L V6 (VIN Code T or M): There
are two bleed valves. They are located
on the thermostat housing and the
thermostat bypass tube.
3.4L V6 (VIN Code X): There are
two bleed valves. They are located on
the thermostat housing and the
heater inlet pipe. 4. Fill the radiator with the proper mix,
up to the base of the filler neck.
If you see a stream of coolant coming
from
an air bleed valve, close the valve.
Otherwise, close the valve(s) after the
radiator is filled.
5. Rinse or wipe any spilled coolant
from the engine and compartment.

IO. Then replace the pressure cap. Be
sure the
arrows on the pressure cap
line up like this.
1 1. Check the coolant recovery tank.
The coolant level should be at
HOT
when the engine is hot and at
COLD when the engine is 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 trafEic 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 your tire goes flat, the
next section
shows how to use your jacking
equipment to change a flat tire safely.

CAUTION I
A
If you let your tires spin at
high speed, they can explode
and you or others could be injured.
And, the transaxle or other parts of
the vehicle can overheat. That
could cause an engine compartment
fire or other damage. When you’re
stuck, spin the wheels as little as
possible. Don’t spin the wheels
above
35 mph (56 lun/h) as shown
on the speedometer.
Rocking Your Vehicle to Get it Out:
First, turn your steering wheel left and
right. That will clez the area around
your front wheels. Then shift back and
forth between
R (Reverse) and a
forward gear, spinning the wheels as
little as possible. Release the accelerator
pedal while you shift, and press lightly
on the accelerator pedal when the
transaxle
is in gear. If that doesn’t get
you
out after a few tries, you may need
to be towed out. If you do need to be
towed out, see the
Index under Towing
Your Oldsmobile.
