ECT/EOT oil temperature alarm

Is there a dash alarm for temperature spread between the ECT/EOT? Posted this in the Excursion forum, may be better here.

If I remember correctly, it depends on the level of OE programming you have if it will throw a service light.

I'm not up on all the programming changes Mark, any idea if the Excusions ever could have that program while not mentioned? It looks like limited to 2005+.

I don't think they did. Who knows if they ever had an engine replacement though.

Mine is an 03 and I'm the original owner. Most maintenance at the dealer except for the last two oil changes.

i bought my 03 new and have seen deltas of 22* difference without an alarm [223* -245*]. I replaced the fan clutch and the oil cooler and still see pretty much the thing with a 13,000 lb rv in tow on a 5 or 6 mile 6 percent grade hill. When unloaded my deltas show a 3 to 10 degrees difference with much cooler temps.

I realize that and it will definitely go up with a load behind it, but i wish the EOT wouldn't go this high, but what do I know. I have to wonder where it will go when i put the motorcycle trailer behind the 5th wheel, which I can do in Tennessee.

As I have posted several times - I can be driving 80 into a headwind, or I can be pulling a trailer (I don't pull heavy ones though), and I am still at 10 degrees or less differential. I have an OEM oil cooler.

Just a data point.
