Hey there i got a 05 f550 6.0 auto 4x4 25,000 on new motor it has head studs egr delete coolant filter banks intercooler and 6 gun bundle with 2.0
Problem is coolant is hotter than oil ex. 216 coolant 212 oil only at first hill in am , levels out on highway 202 ect 208 eot, at 110k . in town seems to stay even 200/200. After a hard pull when its idiling before a shut down , oil and coolant will cool to 200, and sometimes climb to 208, tranny temps climb to ,forgot to mention eot and ect never go more than 10 apart any help would be greeaaat
I have never seen the ect pass eot past 192, besides the last week, the thing that makes me nervous is why it only cools to 200 at idle than starts climbing temps to 208 , untill now after a temp of 212 it would cool to 185 in less than a few mins at a idle
In my case my coolant temps will be higher while in town driving or stuck in traffic (198-200), and after I'm on the freeway or backroads it cools down (188 - 192) after the thermostat opens up past 190 degrees. I think it would be worth while to swap out your thermostat, it's about a 30 dollar part from ford and should take < 30 minutes to do. I change mine out every time I do a full system flush with restore and restore plus, just because the coolant is so darn expensive, I dont want to have to dump it to fix a thermostat.
Yup took rad to, rad place had it flushed, you could be right maybe i dont have a problem , i just noticed a big change in my temps, and like i said before the biggest thing is the truck doesnt cool passed 200 at a idle thats what im most concerned about, im gonna hook a high idle switch up tonight see if that helps
Are you running your A/C? When the engine is up to normal temps look at the fan under the hood and see if its "floating" (as i call it) or is it pulling a good amount of air
No ac , thats another problem haha, i was thinking that as well about that fan, it does seem to be floating, but i do have a spare fan i could try changing it just to see for what it take
Right , ya i have autoengenuity and banks iq 2.0 in truck no codes
