I was just reading on here that someone had EOT and ECT of 205 thinking it was too high.. I can get that with no load on the freeway, but towing I have seen 219 and 220.. What is too high?

The PCM will derate the engine at these conditions
ECT of 221*f
EOT of 253*f
In the Summer when its really hot and I pull this one hill its really steep and Low Speed Limit I get into that 218*-220*f Range But then my Fan Kicks in High and Drops Temps Fast
Some Folks that Dont have the EGR Valve plugged in may Not get the Fan to kick on High
So its Very Important to have the EGR Valve Plugged in EVEN With a EGR Deleate so the Fan Works like it should
Some Trucks Kick the Fan in High at 212*f so it does Vary some But the Main ones are the first ones I posted that Derate the engine or makes it go into Limp Mode
The 205* in the other thread is Nothing to be concerned with Unless there ECT vs EOT Spread was More than 15*f
Lots of time folks will be pullen a Load middle summer and they will Blow Right Past that ECT 221*f and they Make NO Mention of Power Loss. So to really see the PCM Derate you will have to watch EGT cause that will really change

OK, thanks for the piece of mind lol.. I thought at if it was too hot at 205 this thing would have burnt to the ground by now.
Its all stock so everything is plugged in and just did a new t-stat and flush, no loss of coolant or bubbling so I assumed it was ok. Maybe I should turn the stereo down and listen to the fan next time. Been camping every weekend since feb and its the same reading every time. I notice when I get out and leave it running to cool the turbo down the fan is on though..

I don't think I've ever seen over 190* TFT. When the fan kicks in, you hear that sucker.

The gage moves to red at 280. This is supported on page 36 of the OBDII Theory and Operations manual. The tow/haul light will flash at 275.
Over 220 is really too hot for continuous service IMO - most likely something is not right when you see temps continuously this high. Never exceed 250 for more than 30 minutes for reasons below.
Mark Kovalsky (former Ford tranny engineer) says the fluid can get to 300 for a SHORT time w/o any seal damage (however a measured temp of 250 could actually mean that some areas and parts may already be as high as 300 - normal tranny fluid is good to 300 or so, but your tranny isn't!).

190 for oil and coolant? Mine will warm up to that but it stays around 190 to 198 in town.. towing is a different story. TFT has only gone to 161 as far as I have seen.
I need to get a guage for EGT's though.

No, TFT only I don't think I've seen over 190*. ECT/EOT are well into the 200s* easily. I should pull the records from my Edge, I know I've seen 215* ECT and at least 235* EOT, pulling in the summer down here gets things HOT in a hurry.

Don't get caught up staring at all the numbers, you'll drive yourself crazy and forget to just drive the stupid pile or iron. The odds of you slagging the truck driving around empty because of not watching your gauges is pretty small, the truck will do SOMETHING funny for almost everything except nuking the coolers, EGT and fuel pressure. If it doesn't so something weird odds are the gauges wouldn't have caught it before it happened anyways. When you're empty, most of the PIDS you can get away with checking weekly and forgetting about.

Yeah I know what you mean there. Its worse than texing and driving.. I am mostly talking about towing which I have been doing for the last two months every weekend. I never see or worry about them in town unless I am just waiting for the truck to warm up.

You'll get used to processing what's important and when. I go by the rough rule that long grades=EGT, fan noise means check ECT/and the EOT split, and the dash board trans idiot needle budging means check TFT. Boost is the oddball, I watch boost more than I watch my speedo. Mainly for economy, I swear I see the fuel needle move at 15+psi of boost.

That's a good way to put it. Thanks. I watch my boost a lot too, I still havn't found someone reputable in my area that believes in cleaning the trubo.. I have a slight over boost and have been told on here to clean the unison ring but I don't want to take it to the dealership.

Courtney, I run 198 to 204 ect almost constantly once up to temp. It's not a problem. Better combustion the higher the temp. within operating parameters. Your eot then can be compared to those numbers. Spread doesn't count if climbing, cresting or descending a hill. Don't get obsessed with the #'s as texastech said. I've never seen over 185 tft towing 31' 5er up the Sierras out of Bishop, Ca. Your #'s seem good. Enjoy the truck.

There's a guy here, his s/n is ChrisAU. He's cleaning his turbo on his kitchen table, if you PM him and ask I'm sure he'd give you a no-BS run down of how hard it is. I'm pretty sure it's shade-tree-do-able, if you take some time and read/watch videos in advance. Pulling the turbo isn't difficult, it can just be intimidating if you've never done it. Plus the absolute worst case if you completely and utterly destroy the turbo is you buy a Powermax for around $1200, so if that's still cheaper than getting someone else to do it for you, I'd say dig in yourself.

I see ECT of 206-208 on hot days with a fairly hilly and curvy road over my daily 30 mile commute to work. Plus the fact that they just raised our speed limit to 75 helps raise it too. EOT stays 7-9 above but I have seen a difference of 11 but that was hammering her pretty hard(non towing) but it came right back down to the sustained 7-9. Not as worried as I once was as alot of people were saying 190 was it. Mine hovers 190-193 at its lowest during the day, under cooler night temps it has dropped 187-189.
