M1111002700462

1. Start the engine and allow it to warm up until the 

temperature of the engine coolant reaches 80 

− 95°C (176 − 

203

°F).

2. Connect an engine tachometer.
3. Disconnect the ventilation hose from the positive crankcase 

ventilation (PCV) valve , and connect a vacuum gauge to the 
ventilation hose. 

4. Plug the PCV valve.
5. Start the engine and check that idle speed is within 

specification. Then check the vacuum gauge reading.

Idle speed: 650 

± 100 r/min

Minimum limit: 60 kPa (18 in Hg)

CYLINDER BLOCK HEATER UNIT CHECK

M1111004800023

1. Remove the front number 1 exhaust pipe. (Refer to GROUP
