I remember seeing a post from GDE about how there's a fueling restriction after 90 seconds of continuous full throttle, most likely for EGT reasons. These aren't heavy haul engines that are designed to run at max output continuously.

I like having unbuffered gauges. My father's 2005 F150 has idiot gauges. Temp, oil pressure and voltage all settle right in the middle and never budge. The oil pressure gauge gets me the worst; it shoots right to the middle immediately after cranking before oil pressure would have a chance to build.

Re: Please Advise Maximum Coolant, Oil and Trans Temps

My experience is exactly like Phillytx - 15,000 miles of towing a travel trailer about 4500 lbs fully loaded, over serious passes in the Colorado Rockies, Canadian Rockies, and the Alaska Highway. The needle moves next to, but not into, the red zone on long grades. I have just gotten used to that. Other than the temp guage, it doesn't feel like it's even working hard.

Lots of people worry here in Oz too, but in my experience it simply isn't an issue.
I tow a 3 tonne caravan and have had zero issues with coolant, oil and transmission temps. I always monitor when towing with an OBDII sender hooked up to my iPhone, when towing any significant distance.
Yes the gauge moves a lot, but it doesn't lie like many other brands, and no, I've never looked like getting into the red, though it moves up there close to the red.
The highest temps I've seen are around 100C in the transmission (212 F) and from memory, 120C on oil and maybe 115C for the coolant.

I'm at the point now where I watch it, but just don't worry at all. I've towed up big climbs in very hot conditions, and there is just no issue.

I'd much rather have a gauge which tells the truth. My wife's Hyundai can be going down a range in mid winter, or climbing one on the hottest summer day, and the gauge doesn't move, total rubbish.

Don't lose sleep over your temps. They'll almost certainly be fine.

Re: Please Advise Maximum Coolant, Oil and Trans Temps

I just bought a scan gauge X gauge to monitor actual coolant temp and EGT temps at 3 locations. Haven't had a chance to monitor anything yet.

Just want to see actual info for piece of mind when towing. Wish FCA would have added those 2 to the dash info display like trans temp & oil temp was.

No one has discovered the torque PID trick to show Trans temp. If you put the guage you think is Trans temp next to coolant temp, you will find it matches. At least we can watch the Trans. temp on the EVIC instead.

Re: Please Advise Maximum Coolant, Oil and Trans Temps

I just completed a drive from Florida to Tennessee. The ambient temp was about 75-80max and I had the cruise on 85. I saw 220-222 F on the transmission oil. It was past center on the gauge but not near orange or anything. I was not towing but I had a yakima roof box and 2 bikes on a bike rack. I wasn't concerned until I read this thread with ya'll talking about 212F being high while towing.

Not sure where you read that, I went back and re-read the thread and saw most here saying they see 250F when towing, and that 250 was not too high or in the red. 212 was the max that Futuresystem saw, but doesn't mean it was bad.

I see people stating 250 oil temp, not transmission temp. I never saw my oil temp above 205 but transmission temp was 220-222. I'm not really worried about it, just adding another data point.

Re: Please Advise Maximum Coolant, Oil and Trans Temps

Who is it saying that 212F is too high making you concerned?

Re: Please Advise Maximum Coolant, Oil and Trans Temps

I am not sure how bad/normal are my readings, but let me throw my data in the mix.

I usually see 201-205F for Transmission , and 210-220 for Oil. This is in heavy stop and go traffic.

PhilbyTx suggested that max transmission temp is 240/250. I was seeing 220-222 for a sustained period while driving on flat ground at 80mph with mild ambient temperature and not towing. I'm not concerned enough to run to the dealer but, if 240 is near max temp(as PhilbyTx suggests), I would like to see a bit more head room if I were to consider towing in the heat up mountain grades. Does that make sense?
