ECT and EOT after EGR Delete

[superhick8160]

Just did my EGR delete from Sinister last weekend and was wondering if the difference between my ECT and EOT really matter now. I dont have the EGR cooler anymore and I would think that as long as my temps dont get too high I should be fine. Just a thought but and help would be great.

Yes it matters! You don't want the oil getting to hot or you will junk your engine.

Yep! EGR cooler and oil cooler are two completely different things, one you can't live with, and the other you can't live without. Your coolant can still plug up the oil cooler and temps definitely should be monitored.

Your sig says "Next: ??????" Next = coolant filter, if you want to take the above issue out of the equation.

I see you have an Edge Insight, what are your ECT/EOT differences?

I know that the temps matter but I was asking if the difference in temps matter as much without the EGR cooler. My coolant temp usually runs about 185-195 and my oil temp runs anywhere from 195-205. My difference has never been above 20. They are normally between a 10-15 degree difference. Another question is how hot is too hot on the EOT?

Normal EOT=200-220
Severe=220-235
Alarm=235+

Have read engine defuels at 254. Not sure, don't want to find out though.

If they are normally 10 to 15 you sound like you are right on the borderline. I'm not a psychic but I do see an oil cooler in your future. How far in the future depends on how far you want to push it, also if you go to towing I'm starting to see visions of head gaskets.

I would think of doing it sooner than later. Even though you have the EGR delete you can still spew coolant with high oil temps.

I went through the same procedure but not by choice. I had a shop do the EGR delete. Me no knowing, didnt think of the oil cooler or know it should be done at the same time. Needles to say the shop did not recomend it. After some minor issues I ended paying twice the ammount of labor to have it done a month later.

I was seeing oil temps of 30 to 40 and it was spitting coolant when it got hot. Did the oil cooler and all the issues were cured. HG still strong and runs mint now.

Exactly right. Removing the EGR Cooler has taken it out of the equation which is a good thing. It doesn't do anything to prevent the oil cooler from clogging up though. So yes, ECT and EOT are essential things to monitor even having done the EGR Delete.

IIRC the fan doesn't turn on due to oil temp until the oil temp reaches 254*F
