ENGINE COOLING -General Information/
Service Specifications/Lubricant/Sealant14-2
GENERAL INFORMATION
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.

AUTOMATIC TRANSMISSION -Troubleshooting 23-57
Inspection procedure 14
Poor acceleration
Probable cause
If the vehicle does not accelerate after downshifting, the cause is probably a
malfunction of the enginesystem or of a brake or clutch.DMalfunction of enginesystem
DMalfunction of brake or clutch
DMalfunction of engine-A/T-ECU <6G7>
DMalfunction of A/T-ECU<4M4>
LRefer to the Transmission Workshop Manual.
Engine system check
DControl system, ignition system, fuel system, vehicle bodyNG
Repair or replace
OK
Brake and clutch check
L
DCheck for a problem such as burnt facing, poor piston
sealing or interference with the retainer.Check the trouble symptoms.
Replace the engine-A/T-ECU or A/T-ECU.NG
Inspection procedure 15
Vibration
Probable cause
If vibration occurs when accelerating or decelerating while driving at a constant
speed or driving in top range, the cause is probably abnormal damper clutch
pressure, or a malfunction of theenginesystem, DCC solenoid valve, torque
converter or valve body.DAbnormal damper clutch pressure
DMalfunction of enginesystem
DMalfunction of DCC solenoid valve
DMalfunction of torque converter
DMalfunction of valve body
DMalfunction of engine-A/T-ECU <6G7>

LRefer to the Transmission Workshop Manual.
NGReplace the DCC solenoid valve.

Does the problem still occur when theengine coolant
temperature sensor is disconnected?YESEngine system check
DControl system, ignition system, fuel system, vehicle body
NO
Fluid pressure test (Refer to P.23-106.)
DMeasure the damper clutch fluid pressure.
Standard value:Refer to P.23-106.NGDisassemble, clean and re-assemble the valve body.
L
DMake sure that the mounting bolts are not loose and that
the O-ring and valve body are notdamaged or positioned
incorrectly.
DIf the extent of thedamagelooks too bad for repairs to be
carried out, replace the valve body assembly.
OK
Replace the torque converter assembly.Check the trouble symptoms.
