Instruments Drive Axle Oil Temperature Gauges Detroit Diesel engines : 200 to 230°F (93 to 110°C) NOTICE Under heavy loads, such as when climbing steep grades, temperatures that exceed the normal oil tem- perature range for a short period are not unusual. If the temperature returns to normal when the load de- creases, there is no problem. A sudden increase in oil temperature that is not caused by a load increase may indicate mechani- cal failure. Bring the vehicle to a safe stop and investigate the cause to prevent further damage. Do not operate the vehicle until the cause has been determined and corrected. During normal operation, drive axle oil temperature gauges ( Fig.
3.12 ) should read between 160 and 220°F (71 and 104°C). 05/11/2001 f610533 REAR REAR Fig. 3.13, Engine Oil Temperature Gauge F Turbocharger Boost Pressure Gauge The turbocharger boost pressure gauge ( Fig. 3.14 ) measures the pressure in the intake manifold, in ex- cess of atmospheric pressure, being created by the turbocharger. 04/16/2013 f610547 Fig. 3.12, Rear Drive Axle Oil Temperature Gauge Under heavy loads, such as when climbing steep grades, temperatures that exceed the normal oil tem- perature range for a short period are not unusual. If the temperature returns to normal when the load de- creases, there is no problem.
