DIFFICULTY LEVEL
• Genuine Toyota Radiator Hose
• Hose clamps – 2 for each hose
• Genuine Toyota Coolant as required
• Phillips (+ shaped) screwdriver (medium)
• Flat-tip (– shaped) screwdriver (medium)
• Pliers
• Radiator drain plug (hex-head) wrench (if needed)
• Drain pan (large enough to hold 2 to 3 gallons of coolant
and still fit under the vehicle)
• Metal file
• Disposable gloves
• Eye protection
• Rags or paper towels
CAUTION:
DO NOT install a new hose over a damaged fitting.
Smooth out any rough edges with a metal file. If more severe
damage is noted, see your Toyota dealer.

WARNING:
Keep your hands and
tools away from the fan. Do not lean
on the fan housing. If the battery is
not disconnected, the fan could
automatically come on at any time.

DRAIN COOLANT INTO CONTAINER –
Slowly remove the radiator cap to
relieve pressure in the cooling
system. Position the clean container under the radiator drain
plug located in the lower section of the radiator. If the drain
plug is the flat type, using pliers, turn the drain plug
counterclockwise and allow the coolant to drain. If the drain
plug is the hex-head type, use a hex-head wrench, turn
counterclockwise and allow the coolant to drain. When enough
coolant has been drained, turn the drain plug clockwise to
tighten.
DO NOT OVER-TIGHTEN
.
NOTE:
If only the upper radiator hose is being replaced, it is
not necessary to drain out all of the coolant. Drain about one
gallon to ensure the coolant level is below the hose.
NOTE:
If you are replacing the lower radiator hose and the
coolant is over 2 years old, it is also recommended to drain the
coolant from the engine block at the same time as the radiator
(see step 13). Refer to your vehicle’s Owner’s Manual for the
location of the engine drain plug.
3
LOOSEN THE HOSE CLAMP – Using
a screwdriver or hose clamp pliers,
loosen the hose clamp on one end
of the hose and push it back a
couple of inches. The flat-tip
screwdriver may be used to help
move the clamp if it is difficult to
move by hand.
4
DISCONNECT THE HOSE FROM
THE FITTING – Twist the hose back
and forth to loosen it. Pull firmly
on the hose – it will be difficult to
get started but should come off
easily after being loosened. Be
careful not to damage the flange.
5
DISCONNECT THE OTHER END
OF THE HOSE AS STATED IN
STEPS 4 & 5.
6
INSPECT THE HOSE FITTING –
Carefully feel around the outside
lip of the flange with your finger.
Check for rough edges, burrs and
deformation.
7
8
PUSH THE HOSE ONTO THE RADIATOR AND ENGINE FITTING –
Apply a small amount of water or coolant inside of the new
hose and twist and push the hose over the fitting as far as it
will go.
PUT NEW HOSE CLAMPS OVER EACH END OF THE NEW HOSE –
Loosely install the hose clamps 3 or 4 inches from the hose ends.
9
INSPECT THE HOSE INSTALLATION – Check that the hose
routing is correct, not twisted, and clear of other engine
components.
10
INSTALL THE HOSE CLAMPS – Slide the hose clamps over the
lip of the fitting approximately one inch from the end of the hose.
11
TIGHTEN THE HOSE CLAMPS (if screw type) UNTIL THE
SURFACE OF THE CLAMP IS FLUSH WITH THE RUBBER HOSE –
If the clamps are spring type, this operation is not required.
CAUTION:
DO NOT OVER-TIGHTEN the clamps.
12
FILL THE RADIATOR WITH COOLANT – Slowly add coolant to
insure proper filling. Rapid filling will not allow air to escape
from the cooling system. If the old coolant is more than 2 years
old, flush the cooling system with water and replace coolant
with 50 to 70% anti-freeze and 50 to 30% water. Bleed air out
of the system (see Repair Manual for your vehicle’s bleeding
requirements.)
Super Long Life Coolant
is pre-mixed, there is
no need to add water.
CAUTION:
Do not bleed system while
engine is hot – severe burns may result.
m
WARNING:
Do not pour coolant onto
the ground or into a storm drain or sewer
– it is environmentally unsafe and illegal.
Put the coolant into plastic containers and take them to a service
station, recycling center or your Toyota Dealer Service Department
for recycling. USED COOLANT MAY CONTAIN HEAVY METALS
AND IS TOXIC. Be sure to clean up any coolant that has spilled
on your hands, clothes, the vehicle, or the ground. Animals are
attracted to spilled coolant and can be fatal if ingested.
13
RE-CONNECT NEGATIVE BATTERY CABLE.
14
CHECK THE HOSE CONNECTIONS FOR LEAKAGE – Start the
engine and run the engine until it reaches normal operating
temperature, then check for fluid leaks at the hose connections.
15
ESTIMATED TIME INVOLVED
Accessibility problems may exist on some Toyota models such
as the MR2, MR2 Spyder, Toyota Van (’84-’89), Previa and turbo
or supercharged models. Unless you have proper knowledge,
equipment and tools, have your Toyota Dealer Service Department
perform the repair.
INSTRUCTIONS
ALWAYS REMOVE THE KEYS FROM THE IGNITION WHEN
WORKING ON THE VEHICLE. SEE
CAUTION
ON BACK PANEL.
NOTE:
Radiator hose replacement should be performed on a
level surface when the engine is cool. Otherwise the system
will be under pressure and the coolant may be hot enough to
burn. Radiator caps should never be removed when the engine
is hot. Set the parking brake and wear disposable gloves and
eye protection.
1
DISCONNECT THE NEGATIVE
BATTERY TERMINAL CABLE.
NOTE:
On some vehicles, the
alarm will sound when the
battery is reconnected. Also,
clocks and radio station presets
will have to be reset after the
battery is reconnected (refer to
your vehicle’s Owner’s Manual
for instructions).
