OIL PRESSURE CHECK
WARNING:
To avoid danger of being burned, do not touch exhaust man-
ifold when exhaust system is hot.
When servicing, be sure to perform it after exhaust system
has cooled down.
NOTE:
Prior to checking oil pressure, check the followings.
Oil level in oil pan.
If oil level is low, add oil up to full level hole on oil level gauge.
Oil quality.
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to Section 0B.
Oil leaks.
If leak is found, repair it.
1) Remove exhaust manifold cover and then oil pressure switch
from cylinder block.
2) Install special tool (Oil pressure gauge) to vacated threaded
hole.
Special Tool
(A): 09915-77310
(B): 09915-78211
CAUTION:
Be careful not to make special tool touch exhaust man-
ifold when installing because exhaust manifold becomes
very hot.
3) Start engine and warm it up to normal operating temperature.
NOTE:
Be sure to place transmission gear shift lever in “Neutral”
(shift selector lever to “P” range for A / T model), and set
parking brake and block drive wheels.
4) After warming up, raise engine speed to 4,000 r / min and mea-
sure oil pressure.
Oil pressure specification:
390 – 470 kPa (3.9 – 4.7 kg / cm
2
, 55.5 – 66.8 psi) at
4,000 r / min (rpm)
5) After checking oil pressure, stop engine and remove oil pressure
gauge.
6) Before reinstalling oil pressure switch, be sure to wrap its screw
threads with sealing tape and tighten switch to specified torque.
Tightening Torque
(a): 14 N
.
m (1.4 kg-m, 10.5 lb-ft)
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut it off.
7) Start engine and check oil pressure switch for oil leakage.
