Engine water temperature gauge
(Fahrenheit/Centigrade) Fig. 10
The coolant temperature during normal
operation should be between 65°C - 85°C
(149°F - 185°F). If the temperature should
rise above 93°C (200°F) for a prolonged
period of time, stop the engine and
investigate the cause. The engine should, on
the other hand, not be run at too low a
temperature for long periods either.
Engine oil temperature gauge
(Engine mounted)
(Fahrenheit/Centigrade) Fig. 11
The lubricating oil temperature should be
between 80°C - 90°C (176°F - 194°F) when
the engine is hot. If the temperature should
rise above 115°C (240°F), stop the engine
immediately and investigate the cause.
Engine oil pressure gauge Fig. 12
(pounds per square inch/kiloPascal x 100)
The lubricating oil pressure should be
between 300 - 350 kPa (45 - 50 lb/in²) when
the engine is hot. If the pressure should drop
below 200 kPa (30 lb/in²) at higher engine
speeds than idling, stop the engine
immediately and investigate the cause.
Ammeter (Ampere) Fig. 13
The ammeter indicates at what charging
current the battery is being charged by the
alternator, or to what extent current is taken
from the battery without the battery being
recharged.
