We are having a issue with our 1996 fl80 frieghtliner. We recently had overheating issues and found the fan hub and coolant temp sensor was not worn out so we replaced both of them but now for some reason when the coolant warms up to 200 degrees the overheating alarm will go off for a couple seconds and then go off. The red line for coolant on the gauge isnt till 220 or higher so it doesnt make sense why it will come on momentarily.
