On this last trip I found my self hitting 240 on a couple of grades before I backed it down to "creep and crawl" to keep it from getting hotter.

So....I am thinking to go through the usual subjects in this order....thermostat, fan, radiator hoses, water pump, then the radiator itself.

OVERKILL !

Yes, 240 is hot, but with the newer high pressure (21 psi) cooling systems, you still had some cushion. I would always kick down a gear when towing up a grade with with my E150.

My process for "flush and fill".
• Drain coolant. Refill with plain water. Add flushing chemical (Prestone Flush). Double if you have a rear heater. Drive for at least 30 minutes.
• Repeat
• Drain. Refill with 100% coolant (there is still water in the engine). Drive for 30 minutes and then check and adjust the coolant strength


I'm sure he's 2 gears or more kicked down flat footin that setup up the grades.
FWIW, the condition of the coolant in a vehicle that new is far less likely to be the cause than several other things that are far less involved to check first.
