I have a 2008 FR Georgetown. 35' and 22k chairs. We're towing 4k of road.Yesterday, while traveling west towards Boise the engine temp spiked to over 242f. Outside temp was 95-100f. We were traveling 65mph. I have only seen this happen once before with similar ~100f temps. The test of the trip we did lots of mountains but never saw these extreme engine temps.When we slowed to 55 mph the temp was reasonable. If the outside temp is below 95f then we see no crazy engine temperature spikes.Typical operating temperature is about 207f.What have any of your seen with engine temps during hot weather? What about those of your with even bigger f53? Overall, I'm very happy with the Ford v10.

2008...It's 2018 now so it's 10 years old. Ever flush the cooling system, change the antifreeze and replace the hoses? I'd say it's past time if you haven't.

I have seen 150 engine temp here in New Mexico and West Texas with temps over 100 so seems normal to me. I do notice that certain places that outside temp will be 10 degrees higher than the few miles before and after. This has been a very hot year where we live.

Interesting. Mine runs 206CHT and just a bit shy FWT, always has. Scangauge. Just how are you measuring the engine water temp?

Add 3 degrees of additional temperature rise for every LB of pressure on the radiator cap and that will be the peak operating temperature.
