I am lost on temps.....

[police251]

OK I keep hearing different stuff on this topic... I have a 2005 6.0 PSD and i am trying to find out what are normal temps for a 2005 F250. I posted this before and looked on the site but can't get an answer.

I dont have a tunner just 4inch turbo back exhaust. I pull a trailer about 9,000lbs and my temps are wierd... I have a scanguage and when i am towing in the summer its warm in NM about 100 plus sometimes.

My EOT can go as high as 230 and ECT is around 223 they do drop when not on a hill but to me its high. I dont push the truck to pull and do the speed limit. The fan turns on and cools it a little bit, after a hill it will drop to low 200 ot so.. but they dont always stay withen 20 degress of each other. Is this bad and what will help out.

Sorry for the long post.

If the 20* spread is when towing, that's not a huge deal necessarily.

You should take the truck out and get a baseline of running empty at 65-70 mph and see where your temps sit. Personnaly, I wouldn't be comfortable with EOT's over 230 and I haven't seen temps anywhere near that high to date.

They are a little high but so is the heat, how many miles on it has it been flushed still running the Gold junk coolant need a coolant filter to remove the casting sand this will help.

When I am running unloaded, Freeway speed 65 to 70 mph i see ECT of 185 to 198. this is on flat or mild uphill. EOT is 191 to 204.
When I am towing my 7,000 lb travel trailer I see ECT of 195 to 210 and EOT of 205 to 220.
Highest ECT I have seen going up the pass is 220 or so and the oil temp was 6 to 10 above that. Biggest delta was 15 on the back side of the pass and when I saw that I just bumped the rpm up a little and it cooled right down. (did not have tow/haul on)
Hope this helps.

When i am not towing both temps run very close together around 205 EOT and 207-210 ECT the fan does turn on alot but its hot as hell here sometimes. I do still have the ford gold junk in the truck... However i wanted to change it and have looked on this site and get many different answers. I know to change to a ELC but what brand is the best Zerex,Cat, Rottela there are alot.... and I was told not to get 50/50 mix but dont know what is the right way to go please just help I will change it ASAP.....

Look for any post by PGreenSVT and look at the links in his signature and you will find a lot of good information on the 6.0 and the gold coolant.
In fact i would not be surprised if he chimed in here soon.

I will look I need to change this gold junk out...

Always use the concentrated stuff, no matter which you use. As long as it is EC-1 rated, your choice.

Seem just a little high but the temps are directly related to ambient air temp! The hotter the air is going across the intercooler, radiator, etc, the hotter the coolant temp is gonna be. That cooling system is taxed big time during that senario. Remember the coolant is doing all kinds of work(oil,engine,egr gas).

Sure those aren't reversed?

As for the best ELC, Rotella Ultra ELC is best followed by Delo, and then any of the others are pretty much all the same. Any ELC with a Cat EC-1 rating on the jug is good enough.

Do yourself another favor and run a good synthetic motor oil. It'll handle the heat much better than dino oil.
