Recently, I experienced an unusual situation with a ’98 Dodge Cummins farm and ranch pickup. My son and I were hauling materials to a fence project when a loud howling noise came from the engine compartment.

Let me suggest an experiment you can do at home: On July 4, dive deep in the closet to pull out your heavy winter coat and wear it on a leisurely stroll across your pasture. If you don’t feel the urge to spend the rest of the day cooling off in the nearest water trough or creek, you probably are in the early stages of heat stroke and should call 911.
