Looking for opinions on acceptable Coolant and oil temps to watch for on the guages (PMT), so far the worse I've seen is both at 210 at 105K (65 mph) on the highway. Should they always be fairly close to each other? How much allowable difference?

Thanks !

My understanding is that they need to be within 25* of eachother. More than that is an indication that the oil cooler is heading south.

Actually, that has been revised down to a max of 15 degrees difference......

Mine must be good then - < 15 degrees - usually within 5

Thanks Guys - Ain't these trucks fun !?
