Thank you for the responses so far. I asked this person for more details of this overheating claim. It goes like this:
The diesel engine is in the rear, the radiator is in the rear. His theory is that when or if there was ever an OIL LEAK, the oil leak while driving gets on the radiator, clogs the radiator not allowing it to cool. Even after the oil leak is repaired, the radiator remains clogged until it is removed and cleaned. Hmmmm............
Your coworkers theory has some merit but the overheating due to radiator oil fouling isn't a west Texas or even the time of the year problem. You could overheat anywhere and time with a fouled radiator stack. Outside air temp contributes some but is normally not the trigger for an event. The problem with the theory is specific multiple events must first occur to achieve the end result of an overheat all of which can be avoided with a proactive and effective preventative maintenance program.
And the problem isn't unique to rear engine diesels. The oil fill on a Ford F53 chassis is directly above the left corner of the radiator. Get sloppy during an oil change enough times and you'll easier foul the radiator. Transmission dipstick, and the only way to refill after a drain, is over the right corner.
