2008 TOYOTA 4RUNNER coolant temperature

395
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in P".
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of death or serious injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 S t o p th e veh i cl e on a level fi rm
ground, firmly set the parking
brake and put the transmission
in P". Block the wheel diago-
nally opposite to the one being
changed if necessary.
If you have a flat tire

425
Doors and engine hood
Check that all doors including back door
operate smoothly and all latches lock se-
curely. Make sure the engine hood sec-
ondary latch secures the hood from open-
ing when the primary latch is released.
Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 441 in Section 7−2
for additional information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
443 in Section 7−2 for additional in-
formation. When checking the tires,
make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires according to the
maintenance schedule. (For
scheduled maintenance information,
please refer to the Scheduled
Maintenance Guide" or Owner ’s
Manual Supplement".) See page 445
in Section 7−2 for additional
information.
Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat−looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake pedal; pedal almost
touches floor; vehicle pulls to one side
when braking
Engine coolant temperature continually
higher than normal If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
Does your vehicle need
repairing?

To ensure excellent lubrication perfor-
mance for your engine, Toyota Genuine
Motor Oil" is available, which has been
specifically tested and approved for all
Toyota engines.
Please contact your Toyota dealer for fur-
ther details about Toyota Genuine Motor
Oil".Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the F" and L" lines on the reservoir.
If the level is low, add the coolant. (For
the coolant type, see Coolant type
selection" described below.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the L" line, add
coolant. Bring the level up to the F" line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use Toyota Super Long Life Coolant"
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life
hybrid organic acid technology. (Coolant
with long−life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
For the U.S.A.Toyota Super Long Life
Coolant" is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35
C
(−31 F).
For CanadaToyota Super Long Life
Coolant" is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
(−44 F).
