GEN2 (2019) Engine Running Hot, Phaser Sound Again After 10K From Repair

[Space Ghost]

Mine runs around 219-222ish had the dealer check it out because I thought it was running hot after the coolant flush. They said it was running at normal operating temperatures. I'm also in 90+ degree weather, it hit 233 in 115 degree weather on a road trip going up a grade at 82 mph. Which is why I had the dealer check it out.

the first # range isnt unreasonable for hwy speed with some headwind in hot weather

the new thermostat from ford dropped mine a bit, now its 212-216 going like 80 with some boost cause of headwind. 199-206 regular driving.

Ford Corporate confirmed with me that the warranty service is covered for one year. If I had paid for it out of pocket it would have been covered under that 2 year policy.

Well, this time around it looks like you'll have 2 years of coverage.

hmmm, maybe I'll change the Tstat at some point and see if I get lower temps.

UPDATE: Ford Corporate again confirmed the initial warranty service is only a year warranty coverage on parts and workmanship. Financial assistance was approved at 50%. I negotiated with the Service Director and they finally agreed to do the service at their expense given the circumstances.

The phaser replacement was done, they also did the valve cover replacement after finding oil all over the place.

I drove the truck home and it still ran hot just climbing the small mountain range with nothing in the truck (I'm not a big guy -stop it I know what you're thinking). Hit 232 temps.

Disappointing. Back to drawing board about running hot. Perhaps yet another thermostat replacement. Mystery remains at large.

did they replace the thermostat once already?

They did not. It's not part of that service.

Would you suggest doing so? The cooling fans kick on when just climbing a 1/4mi steep hill heading home. Truck isn't overheating, it's just gets hot quickly. I would argue the thermostat is acutally doing it's job as I'm hearing the cooling system engage at ~200* temps.

This is why I'm concerned the engine has other issues causing excessive heat, despite the services....

100 percent, they tend to stick after they are exposed to atmophere for whatever reason. Many of us have had this issue.

Change the thermostat, take it out of possible cause for the running hot it is about the cheapest repair you can do.

My experience with engine temp ( stock 2018 raptor) is that when it transitions to cold outside, the engine goes from running hot in the warm weather to running hotter in the cold. At temps in the neighborhood of freezing and below, what is happening is the ambient air temp at intake becomes the overriding input which controls when to open the radiator shutters. I have a video of them doing their calibration at engine start, wide open sweep, then closing... And staying mostly closed, even when I load the engine and engine temp gets up to as high as 235F. At that temp, the fans are howling and shutters are open about 1-5%. Is this dumb? Yes! Lesson for me, the last thing I'd do is replace the thermostat. No way that helps this situation. It needs an ECM intervention. Coincidentally, I had just flushed the cooling system and I thought for sure I had an air bubble in the cooling loop which was causing high temps. But it coincided with a change in weather. Took me awhile to get it together to put a camera up in the front upper grill to watch the radiator shutters. Don't replace the thermostat. At 200 degree and up engine temps, there is no difference between a 160 vs 195 degree thermostat. That is not to say a thermostat change isn't useful for tunes. But stock? don't bother.

This is 100 percent not his issue based on what he describes. Change the thermostat, they stick. A flush and coolant change wouldn't be a bad idea either at the same time.
