I have 2000 cx 460 vision mack truck and problem with oil overheating and coolant temperature is normal,....we put new oil cooler and new oil temperature sensor , truck doing same thing.2 months ago truck was pulling very heavy load through big hills and was overheating because radiator was plug up with same dearth and was throwing antifreeze out , I think from that time something start be wrong with oil...when truck idling oil pressure is under 8 what is very loo and truck shout down.....Did I did something wrong to engine and why is oil overheating...thanks I had 4 mack truck and never have same problem...thanks
