The oil cooler is very hard to flush and expect any change in the temps. Sadly, looks like you need a new one. At least you flushed all the crap that could be in there into your old cooler.

 

Isn't it a 20* spread 188* ect , 208* eot.

 

My edit didn't go through before you caught me!!!! Yes, I miss read that, and watching football at the same time doesn't help!!!!

 

I here ya lol. Darn was hoping it would have been a easy fix. Looks like I'm going deep and broke. Thanks.

 

You could try and return it worth a shot tell them 180* aint right

When my TFT sender went it was obvious it would be ALL over from cold to redlinehot all withine 5 miles of my house I knew it couldnt be that hot in that short of drive

Does your ect sender act crazy

Maybe they all dont fail the same

Hard to say even with your stand alone cuz the sender in diff spots

 

Ok here's the codes I've been using:

Ect
TXD=07E0221139
RXF=046205110639
RXD=3008
MTH=000200010006

Eot
TXD=07E0221310
RXF=046205130610
RXD=3010
MTH=000901F4FFD8

The ECT is adding 6 which makes the displayed temps cycle from 188 to 192, mostly 190 like I said before and matches the ratings for the MC thermostat that I recently put in. The EOT I found is an older one and may not be the best out there.

Tried the newer EOT in this thread on the way to work, averaged EOT 191, ECT 190.

Because the +6 ECT is matching the thermo ratings I'm thinking I've got it right, somebody wanna check me? BTW I have a 2005 Excursion with a late 2005 6.0, and what Ford tells me is the latest flash on it, maybe that has something to do with it?

Thanks!

 

IMO you should enter whatever codes you have to to make the readings the Dead SAME after 12hour cold soak

It probably dont need 12 hours this time of year when its cold out to Achieve a cold soak with all Fluids at the exact same temp

But a cold soak sets the Base for all Gauges/sensors EOT,ECT,TFT

Once you KNOW the Fluid is all the same temp you can verify the Gauge accuricy

 

As far as getting the temps after a cold soak, don't the glow plugs interfere? My SG doesn't like getting turned on before the key, some readings freeze.

 

My SGII dont like to be turned on before the engine is started either

So set the gauges you want tosee the night B4 the GP should have Little affect and catch those reading ASAP when its started

 

Did you try this with out the 6? You can run, I think, both f*WT and this ECT at the same time. Compare them, and let us know.

TXD: 07E0221139
RXF: 046205110639
RXD: 3008
MTH: 000200010000
NAM: ECT

I have not done this gauge, guess I should.

 

I'll double check the temps in the morning but IIRC they were 3-4 degrees apart after about 8-10 hours. I ran the regular fWT and ECT together for a day or so (not the +6) and they were about the same readings, about 184-186 average, but it was funny because they wouldn't increase or decrease at the same time, possibly a lag in the SG reading the PID?

The 184-186 range was what gave me the +6 idea. I did once check the odometer test temp value (hold odometer button and turn key on) and it showed a little below what the SG was showing, IIRC.

I still can't figure why a new MC thermostat would operate a few degrees low, as I've seen other posts where people are getting the 184-186 range, not the 190 as expected. I wonder about the bad thermo batch, or if different build dates / flash might be involved?

I've seen some SG users posts that report the right 190 or so temps too. I figure if the 15 delta is that important we better be darn sure we're getting the best results we can! Still love the SG but I still think the ECT / fWT may need some tweaking, at least I hope so!

 

Considering the location of those sensors and the mass of the iron involved between them and the glowplugs there will be little, if any at all, affect on the temperatures.

 

Agreed, the gp's heat the combustion mixture, not the coolant or oil. Would take all day for them to make a diff. in block temp.

 

Here is f*WT, ECT, EOT altogether this morning. I'm not sure where the f*WT reads from. (almost 4 day cold soak)

It's a 10 second video, but just look at the still shot below if you don't need to watch 10 seconds of that! lol

So, I will be running it this way and see what happens. But, as it shows, I think the ECT will stay and the f*WT goes.

 

Those temps look good to me. 1 degree ain't no sweating issue.
