wolfe10ExplorerMay 20, 2013No question. At 8 years old, even if it were an OAT-based extended life coolant (which was NOT fit by any chassis maker) it would be time to change.For regular coolant, 3 years is normal life. Perhaps push that a little, but not to 8 years.BTW, Caterpillar also recommends changing the thermostat(s) at 3 years, so add that to the list.
