Engine water temperature gauge
(Fahrenheit/Centigrade) Fig. 6
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 investi-
gate the cause. The engine should, on the
other hand, not be run at too low a tempera-
ture for long periods either.
Engine oil temperature gauge (Fahrenheit/
Centigrade) Fig. 7
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. 8
(pounds per square inch/kiloPascal x 100)
The lubricating oil pressure should be
between 300 - 350 kPa (45 - 50 lb/in
2
) when
the engine is hot. If the pressure should
drop below 200 kPa (30 lb/in
2
) at higher
engine speeds than idling, stop the engine
immediately and investigate the cause.
Ammeter (Ampere) Fig. 9
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.
