There is no upgrade on an nhc250 truck. You can supplement an added air charged oil cooler like I did but you aren't doing what I was doing with it. I did it to get some heat off the motor along with an air charged transmission cooler and ditched the heat exchanger.
Drain the antifreeze. Drain the oil. Refill with fresh oil and filter and run it and see if it runs bad and Or blows white smoke. Do not put antifreeze back in it
A bad oil cooler can put antifreeze into the engine oil especially if its been sitting. Being rusted thru.
