Check the following items in the engine warming-up operation.
Engine oil pressure

ambient temperature, a type of oil or engine specification, the gauge
registers the values of the following in the warming-up.
Oil pressure : 147 kPa (21 psi) /1000min

294 kPa (43 psi) /1800min
-1
343 to 686 kPa (50 to 100 psi) /2200min

In the oil pressure warning lamp type, make sure that the lamp is off.
Charge condition
The charge condition is normal when once the ammeter registers plus
side greatly in the engine starting, then gradually the meter registering
will be minimized.
In the warning lamp type, make sure that the lamp is completely off
during the warming-up.
