Best way to keep ECTs and EOTs in paramaters?

[Power2336]

I installed the CTS and noticed that my EOTs and ECTS hit hight 190 and I have seen 201 once. Some have told me that 180s and 190s are normal but above that to be carefull. What I am curious to know is a way to keep those in safe opereating paramaters. Is there a way to keep them in check as I am waiting for my SCT to arrive and then use Erics tunes. I will not be using anything to hot as I have my stock head bolts and EGR and stock tranny. Just a dect Xstreme street, street and tow tune set for 8k.

Coolant Filtration, hopefully your oil cooler isnt half way clogged. Coolant Flush and Oil cooler rebuild so you know everything is fresh on the coolant side, thats me though.

So flush coolant and repalce and maybe put in new oil cooler? Just wanting to make sure I understand is why I sound like I am asking again lol. Not a big mech when I comes to diesel and wanting to learn all I can.

[RescueF250]

Yes exactly, I mean your probably fine with your factory cooler. How many miles on the truck ? The oil cooler rebuild kit is like 300 bucks, you can actually do it yourself if you take the time and weekend at it. As for right now do the coolant filtration from Diesel Site, after the first month replace the filter and cut the old one apart and see how much sand and crap is inside then go from there. My rule of thumb is replace it 1 every month for 3 months that should get the most of the junk out in the system which is the casting sand thats in the block.

On a hot day my oil will get to 205 maybe higher.. I think that's normal? What I've been told

[tyhackman15]

My Oil will run around 210 if its 85 or hotter out. That's on the highway doing about 75-80MPH

I am starting to see that it is normal to run a lil hot as long as it does not stay there to long.
RESCUE250: I looked at the site and saw the coolant filter. Have you installed one of these? It looks somewhat easy to do but curious if I need to take turbo off like in a photo they have on their site?

First consider the relationship between your coolant and oil with the way they react in the oil cooler (HINT: OIL COOLER). The coolant is passing through the cooler to remove the heat from the oil. Since the outside air temps dictate the amount of cooling efficiency that the coolant will be able to provide inside the motor. High outside temps will make the coolant run hotter than normal and hence the oil temps will stay higher as well.

There is NOTHING wrong with your EOT and ECT temps being over 190*F while towing, driving through hills or especially when outside air temps are higher (say 90*F+).

You should monitor the CTS and follow what the EOT and ECT do realizing the outside temps. Once you get a feeling how your temps roam day to day/ day to night if you find they will not drop down then you have an issue to address. Getting an oil cooler kit so you have it ready is a wise choice.

I have seen my temps run from 190-200 for EOT and ECT with just daily driving due to the outside heat. I consider what I see normal with no real concern. If you are wanting to play it safe do a coolant flush, replace the cooler, change the oil, install a coolant filter and watch the temps.

Thanks HeavyAssault. I see and agree with what you had to say. I do see daily driving in the 190s and the outside temp is about 75. Once I got my CTS I noticed these temps and was curious. I understand that towing or driving up hills and the outside temp would make it raise. I think I am going to go with the coolant filter for now, put some AMS synthetic oil in and see how my temps are with the warmer summer temps finally hitting here in San Diego. Thanks for all the help.

Just got an Edge CS from FCDP and hooked it up yesterday.
My ECT & EOT were in the upper 190's today with air temp
around 85-87 degrees. The truck is an 06 with less than
11000 miles with an SCT running tunes from Innovative Diesel
and a turbo back MBRP Coolduals exhaust with no cat.
