COOLING SYSTEM BLEEDING
NOTE:
Whenever cooling system is drained on Celica, special cooling system bleeding
procedure needs to be followed. No special procedure is required for any other
models.
CELICA
NOTE:
The following procedure assumes that cooling system has been completely
drained by loosening radiator drain plug on bottom of radiator, and engine drain
plug on the coolant drain union located on left rear of cylinder block.
1. Remove upper front fender apron cover and upper radiator support cover to access radiator coolant
reservoir tank and hoses. Loosen 2 coolant reservoir bolts and 3 reservoir hose retaining clamps. Raise
coolant reservoir and place on top of air cleaner cover. Support reservoir from above with wire to prevent
reservoir from falling.
2. Remove cooling system bleed plug. Ensure radiator drain plug and engine drain plug on coolant drain
union are closed. Add approximately 4 qts. (3.7L) of 50/50 mix of water (preferably distilled water) and
coolant to reservoir tank. DO NOT use plain water or alcohol base coolant. Continue to add water/coolant
mixture as necessary. If cooling system does not require approximate refill capacity to maintain coolant in
reservoir at the FULL mark, air exists in system or system was not properly drained. See
4-CYLINDER
COOLING SYSTEM SPECIFICATIONS
table.
3. If cooling system will not take additional coolant, squeeze lower radiator hose while blocking off bleed
plug opening with finger. Continue to do this while slowly adding coolant. Start engine with reservoir cap
and bleed plug removed. Ensure A/C switch is in OFF position, if equipped. Run engine until cooling fan
comes on and goes off one time. Add additional coolant to reservoir as necessary.
4. Install bleed plug and reservoir cap. Rotate reservoir cap 2 1/2 turns until click is heard. Increase engine
speed to 3000 RPM for 5 seconds, and then allow to idle for 5 seconds. Repeat this procedure for at least
15 minutes. Turn off engine and allow engine to cool completely. With engine completely cooled, coolant
level in reservoir should be between LOW and FULL marks. Next time engine warms to normal
operating temperature, coolant reservoir level should be above the FULL mark.
5. Reinstall engine coolant reservoir. Reinstall covers. Check for coolant leaks.
DRIVE BELT ROUTING
Automatic belt tension is used to provide proper tension on serpentine drive belt. For serpentine drive belt
routing, see

BELT ADJUSTMENT
Ensure all drive belts are adjusted to proper tension. See appropriate BELT ADJUSTMENT table. On models
with an automatic belt tensioner, no adjustment is necessary, but serpentine drive belt must be properly
installed.
