Reply to "Ron Davis Oil Cooler"

any chance the timing is off slightly?  Is it slow to crank once hot?

I've learned on this forum that if it isn't boiling over then it isn't really overheating. I do watch my gauge constantly but have learned that it may not be 100% accurate especially when the temp is increasing quickly.  I have the diode mod on my temp gauge as well and pretty sure the rate of temp change isn't accurate.

I had to experiment with my header tank coolant levels to figure out the right coolant levels.  Too much coolant and it will puke out with the air bleeding off.  Seems like about 6" from the top of the radiator cap is where mine is happiest.

For reference my Raptor will run about 230F on the freeway if I'm pushing it up to 80-85MPH.  If I back off, then it drops back down into the 220F range.  I know this isn't an apples-to-apples comparison but a good idea on temp.
