Oil Pressure Check
WARNING:
To avoid danger of being burned, do not touch exhaust manifold when exhaust system is hot.
1) Prior to checking oil pressure, check the following items.
Oil level in oil pan.
If oil level is low, add oil up to full level mark (1) on oil level gauge (3).
Oil quality.
If oil is discolored, or deteriorated, change it. For particular oil to be used, refer to Engine Oil and Filter Change .
Oil leaks.
If leak is found, repair it.
2. Low level mark
2) Detach degassing tank from its bracket.
3) Disconnect oil pressure switch connector (1) and remove oil pressure switch (2) from oil filter unit bracket.
4) Install special tools (oil pressure gauge) to vacated threaded hole.
CAUTION:
Be careful not to make special tool touch exhaust manifold when installing because exhaust manifold becomes very hot.
Special Tool
(A) : 09915–77311
(B) : 09915–77420
(C) : 09915–77430
5) Start engine and warm it up to normal operating temperature.
NOTE:
Be sure to place transmission gear shift lever in “Neutral” and set parking brake and block drive wheels.
6) After warming up, measure oil pressure.
Oil pressure specification
100 – 140 kPa (1.0 – 1.4 kg/cm², 14.2 – 20.0 psi) at idle speed
330 – 370 kPa (3.3 – 3.7 kg/cm², 46.9 – 52.5 psi) at 3,000 rpm
7) Stop engine and remove oil pressure gauge and attachment.
8) Reinstall oil pressure switch (1), and tighten switch to specified torque.
Tightening torque
Oil pressure switch ( a ): 35 N·m ( 3.5 kg-m, 25.5 lb-ft)
9) Connect oil pressure switch coupler (2).
10) Install degassing tank to its bracket.
11) Start engine and check oil pressure switch for oil leakage.
If oil leakage is found, repair it.
