Temp Gauge Discrepancy

[mister_mcgoo]

Hey there,

I noticed on my SR5 that there seems to be a bit of a discrepancy between the main engine temp gauge on the left side of the dash versus the middle engine temp display that you can choose to display..

The “bar” display on the left side reads the normal four bars, while the center seems to read much less.

I typically atleast let my temp get up to one or two bars on the left from a cold start before driving off (might be a bit overkill, but it’s always been a habit to let the engine atleast warm up a min or two).

The center display does eventually rise to normal operating temps after some driving, but it’s just something I noticed this morning.

It’s honestly not a big deal to me, but I was just curious if anyone else has noticed this?

Thanks!

Following. I don’t have the canter display showing temp. I too like to warm up in colder temp.
Curious, if that is oil or coolant temp. Maybe they are different???

The one on the left is water temp. The other is oil and trans temp

Thanks for the clarification! (I feel stupid now )

Yep, I see the symbols now. Was originally looking on a small phone without glasses

I have it figured out thanks to a look at the manual - Around page 96.

The large left gauge is Coolant Temp.

The smaller configurable gauged in your pic are:
Top - Engine Oil Temp (NOT COOLANT). Its typical for this to lag behind coolant temp.
Bottom is Transmission Fluid Temp.

Looks like you can display the Oil Pressure gauge and battery too.

I know on my Ford F350, I have a scan gauge permanently installed and I monitor the Coolant Temp versus Oil Temp. There is a very specific delta in the two that you need to watch, something like up to a 7 degree difference at highway speed. if it's not, you have issues.

Hope that helps.....

the oil and trans temp will be useful during off roading and towing

Modern engines do not need to be warmed up, at least in most temperatures we are likely to experience. If it is really cold it still probably needs no more than 30 seconds. That said, I accelerate more gently for a short time. I notice that mine (not cold temps here yet at all, still no lower than 60s (F) warms up *very* fast. I start it, go to the bottom of my driveway--about 150' downhill--get out, open the gate, roll through, get out and shut the gate--and at that point or very soon after the engine shuts down as it is warm (hybrid version). If I watch the guage I would say it is at full temp within about a minute. A far cry from old engines! So warming up an engine is mostly one of those old habits .

I have also noticed that the electric motor (again, i-Force hybrid version) gives more boost while it is in that brief warm-up period--presumably to lessen the load on the engine.

the only issue i usually see in extreme temps is that the trans fluid is super thick for a longer duration, and it takes forever for the trans to shift properly. i can go for up to .5 to 1 mile before it will shift into OD in my limited currently doing 30 mph from my work building and toward the exit gate of base.

the only other concern i have with the hybrid is that extreme cold could render the vehicle unable to start.

When the hybrid battery (traction battery) is extremely cold (below approximately -31°F [-35°C]) under the influence of the outside temperature, it may not be possible to start the hybrid system. In this case, try to start the hybrid system again after the temperature of the hybrid battery increases due to the outside temperature increase, etc.

When the outside temperature is extremely cold, the hybrid system may be started by starter motor.
■Starting the hybrid system by starter motor
●When starting the hybrid system for the first time after more than approximately 10 months since
the last time the hybrid system was started by the starter motor
●When the outside temperature is extremely cold (the hybrid system may be started by starter motor)

and yes we do get to the -30's ambient at times during february in ND

I did say most of us ;-). agreed, temps that low might benefit from a bit of warm-up, but still probably not long. And driving it gently is probably better anyway, as that will get everything warmed up faster.

lol yeah i understand us people in ND are the exception during winters. it use to be way worse in the 90s before synth and lower value oils where more widely used.

i use to have a block heater in the 90s but now i dont need it since with 0-20w oil vs 10-30/40 was more common back then.

and gear oil is better now than before, i remember i had to turn off my vehicle cause the gear oil was so thick from the cold it would throw christmas lights on the dash.
