I mentioned in my other thread that I have coolant temps that hover around 209* in 50* weather. Now I've been doing this for over 2 1/2 years and notice that my truck runs better than any other 7.3 I've ever driven. Of course I'm tuned, but I mainly use a daily driver tune. But I'm talking more so about a smooth running engine through all the gears. Everything else I drive seems to be rough and just not a very happy engine.
Who else runs hot?

After my motor was rebuilt my oil temps got above 230° with a diesel site 203° stat while on the free way.. switched it out to a 180° stat and it stays around 190° and only gets above that when I flog on the ole girl.

Was wondering about this myself... Usually around 200* for both, summer time at 80* pulling mountains would get to 217* before I'd back off..not sure what's too hot

Not a clue for me....I have no way of monitoring ECT other than the crap factory gauge in the dash. My oil temps run about 195-215 depending on the day/driving conditions though.

Not to derail. But what is "too hot"?

copied this from my thread over on psn. it was a reply to my question of what temp limits are for these trucks:
Everyone seems to think 1200* egt but more is ok for short durations. I have run mine to 1400* passing a semi on a 2 lane towing up the mtn just long enough to make the pass. EOT? depends on the type of oil. But the pcm will defuel @ about 290* I run syn and always see 245/255* while towing over 12K on 9+ miles of 6/7% in 100* ambient temps. Trans, I would be concerned over 230 or so. I added a trucool and never see over 180/185 no matter what I tow or where I tow.Everyone has their own opinions about this.
also i havent towed recently but in the middle of summer in 80-90 ambient temps i hit 215 eot cruising on the highway at 65. thats the highest ive noticed yet but i can get into the insight and check it if its a serious question. how are you guys monitoring the actual ect on a 7.3?

What * TS do you have in it? I have a 203* and it runs a tad hot, but runs better, especially unloaded. I'll have to hook AE up to see what the actual temp is, but I remember it wasn't anything I was worried about. I don't tow heavy often, but when I do she loves it.

How are you measuring those temps and how sure are you that reading is accurate?

I run a 203*, I have no issues hauling with it in the prairies here with light (under 12k) loads, even in the summer. I did however change it out for my trip through the mountains pulling 8k with a 185 or 190* T-stat. I'm glad I did because the EOT did climb to 225 a few times. It would have made me a bit uneasy if the 203* was in there.
I have to install a "weather front"/rad block off behind the grille in the winter even with my 203* or else if the outside air is below 50* the truck won't get above 190* EOT/ECT. With a 185/190* T-stat, it struggles to get above 155* in the winter. In the summer the ECT/EOT is usually always 200-210*. With the cooler temps starting here sometimes the oil does hover about 10-15* cooler than the coolant, but once on the highway or under load it slowly catches up. Mine runs cool, but runs better the warmer it gets no question.

I used to see coolant temps of 230* towing heavy with the 192* stat... I still have a 203* stat on the shelf in the shop...
180* stat is perfect in my book.
Keeps my oil temps below 220* in all but the most extreme conditions.

This is the first winter I have had it in... but thus far with 30-35* temps I have seen the same 190* water temp with 200* oil temps.
We will see when it get's really cold if I have any issues.

What tstat do you have?

This is how I keep the temps "normal" in the winter. Love it and the additional fuel mileage has already paid for the cost of the cover.

I dont specifically watch coolant temps, but the EOT is usually at 194-195 (per the scan gauge) with the car trailer loaded at 8K-- I cant imagine the coolant temp is much different. Ambient at 50-60F with 1500' elevation change; not worked real hard. I dont know which stat this truck has in it.
