ISX High Oil Temp

[Nilao]

I don't think it throws a stop engine light for low fuel pressure, just a check engine light until the pressure returns to normal. The oil temp though will throw a stop engine light. I would start with the oil thermostat as it is the easiest to replace. To do the oil cooler requires pulling the turbo, water pump inlet manifold and egr cooler along with all the lines on that side.
