Maintenance Intervals And Specications
Cooling System Rell Capacities
Cooling system rell capacities vary considerably due to
differences in engine models, variations in chassis, and body
options, in addition to the amount of coolant remaining in the
system after draining. Total capacity may range from 6 to 22
gallons (23 to 83 liters).
If system has been drained, ll with fresh 50/50 diluted
concentrate coolant or 50/50 premixed coolant. If the system
has been ushed with water, a signicant amount of the
freshwater ush will remain in the system. In this case relling
with a mixture with a higher percentage (60 to 66 percent) of
coolant concentrate is advised in order to achieve a nal mixture
close to 50/50.
Fill the system and run the vehicle until the thermostat opens.
Check the coolant concentration and add additional water or
concentrated undiluted coolant to adjust the concentration. Run
the vehicle and retest.
