Coolant was not changed at the time of this test, but looks like it should be. Not sure of the history of this vehicle, not sure what fluid is in there now or how long it's been in service.
I assume OAI copied the manufacturer/model from the diff fluid I sent. This is for a 7.4L 454 V8 in a 97 Chevy C3500 truck.
