What's your engine temp on Ford V10?

[miatawnt2b]

I installed a bluetooth OBDII to monitor engine and trans temps. Unfortunately my F53 is OBDi so it doesn't seem to do trans temp. However it does engine temp and some other stuff.

So I was running 65MPH in Arizona today and my engine temp on the V10 was hitting 208-212 degrees F. It was a balmy 103* ambient today. Does this seem OK? Engine idle temp is about 193*.

Also I was pulling an extended very slight grade in 4th gear at 50MPH. Coach fully loaded. The engine didn't seem to be struggling at all to pull the grade, though it did downshift a couple times for a few seconds. The temp climbed to 213* and the dash A/C turned off. Is this normal at over 100* ambient?

Thanks!

What year is you F53?? Mine would fluctuate a lot in the mountains. Last fall I replaced the fan clutch, water pump, and put in a high flow thermostat. It now hangs solid at 205. The fan clutch kicks in a little more often.

Your V10 should have OBDII and you should be able to read tranny temp. Mine hangs around 170. I watch it like a hawk as my 1999 F53 doesn't have an integral engine radiator / transmission cooler.

I have the Scan Gauge II and to get trans temps on my 2000 V10, I needed to add a code from Scan Gauge into a X gauge.

I moved the guage to my 2017 V10 and needed to change that code.

If you have a V10, You have a OBD II. You may have to research how to read the trans temps.

My 2017 coolant temps run up in the 200° range, climbing a hill, as high as 212°.

My Class A is a 2000 and I believe the F53 chassis is a 1999.

The temps are about what I see on my 2006.

I’m pretty sure all the V10s are OBDII. Besides different communications parameters even the data port connector is different so your blue tooth reader would never even plug into an OBDII port. Check with the reader manufacturer if you can program the reader to display the temp. I also have a Scan Gauge that I had to program for trans temp.

The V10 will self protect if it gets to hot. First event is it will shut off fuel to multiple cylinders and use them to move air thru the cylinders to help cool. If the temp keeps going up the engine will shut down before the heads start to warp, in theory. Sorry I can’t recall the event temps.

Clutch fan starts to engage at approx 209 to 212 full lock up at 215, and it will roar!

2014 Ford F250 train Triton V10 it is pushing / pulling I'll write 35 foot Class A motorhome.
We are on our Maiden Voyage and notice that RPMs really jump from 2200 RPMs to 4000 to 5000 RPM going up steep hills. And the roar is next to deafening.
When I see RPMs approaching 3200 RPMs,
I back off trying to push the engine. Unfortunately, I do not have any of these fancy gauges, and probably couldn't understand it, even if I did.

Is all this normal ?

On my 99 F53, build date 5/99 emissions certification label says it is OBD-I. However, it is OBD-II compliant and codes and engine data can be read with a OBD-II reader.
As for the OP's question about his ScanGauge II reading the trans fluid temperature as twinboat posted it can be done by entering the correct code in the X-Gauge. Need to read manual on how to enter the X-Gauge if you don't have the manual download here,

The V10 is a 5500 RPM engine, you can run it at 4500 RPMs all day.

If its roaring all of the time, see if the cooling fan is locked up and and spinning full power all of the time.

Let try this again seems there is a problem with the link I posted probably because of the "2" at the end.

Like has been said, the fan doesn't either bother going to full lockup until you hit 215F so it would seem to me you're right on. Engine temperature doesn't interest me until it hits 220F.

The changeover to OBDII in the automotive world happened at the end of the 1995 model year. Some "leftovers" didn't get OBDII for another year and some trucks yet another year. The first V10 6.8's came out in 1991. Well inside the OBDI time frame.

However, the F53 chassis did not get the V10 until the redesigned chassis was released in 1999. The previous years up to 1997 had the 460 V8 and they were all OBD-I. There was no 1998 F53 chassis built. The first year for the V10 F53 chassis was 1999 and OBD-II port installed. I have seen members post that their chassis is a 1997 with the V10. Those must have been built very early after redesign of the F53 chassis. If your F53 has a 460 V8 it is a 1997 or earlier and OBD-I. If your F53 has a V10 it is the redesigned chassis and has the OBD-II port.

(Double post) Well that makes sense. I know about the V10 and trucks but am lacking on F53 details. Well I was.
