I think I have a problem...

I received my edge insight cts and hooked it up today and went for a test drive.
At 65 mph my ect was 188-190 and my eot was 200-202, sometimes hit 204. It would cool down a little when I slowed down or came to a stop. Is this an issue, does this mean my oil cooler is bad and will be blowing soon?

I was wondering what the average tranny temp should be, mine was 164-168 once warmed up. It was 85 degrees today.

Trans temp looks fine, oil cooler may be on its way out, we're you on hills or anything like that?

Thermostat is sticking. It should read 190-192*. You have to drive steady 55-65mph for 30 minutes without it being under a load (ie up and down hills or towing) in order to get an accurate reading but your tstat has to be in good order too. 14* separation between ECT & EOT or less is within exceptable parameters.

Trans temp looks fine, no, your oil cooler is not about to blow. But plan on doing a chemical flush, and oil cooler soon. Egr cooler is what its usually in trouble with deltas starting in that range, you may as well change the thermostat also, egr delete if you can. Smart move to monitor, but not all doom and gloom.:thumbup:

It is kind of typical for those with a new monitor to worry unnecessarily if there ECT and EOT aren't hugging each other. I do think you should go ahead and replace your thermostat. Your ECT temps are borderline acceptable but it is an easy thing to change and cheap to do. Make sure your truck is fully warmed up and watch the delta at 65 to 70 mph on a sustained run of 10 minutes or so. If your delta is typically within 10 to 12 degrees nothing to worry about. Around town it should be more in the 6 to 8 degree range or lower. If you see a sustained temp delta of 15* or more it is time to plan your oil cooler swap out, sooner than later. It is still no reason to panic. It is just your warning that maintenance is required so plan on taking care of it.

In your case I say change the Tstat and just keep an eye on things while you learn what's normal for your truck. Every truck is different.

If you were seeing sustained delta of 20 degrees or more I would say you should really look into changing the oil cooler ASAP.

The egr delete was already done, and chemically flushed twice. I was only at 65 for 2 min, flat ground.

I wasn't trying to say that it's about to blow, just that it may be starting to clog a little, sorry if that came out the wrong way

Nothing wrong with your post. It may or may not be. Too soon and not enough info to tell.
