Found the answer to my high temp readings. Finally !!!

[jason]

ok, after being on the phone with an "SCT" tech for about an hour, i finally found the answer to my temps being high on my SCT Livewire 9600. tghe screen finally blurred and went crazy. The tech at SCT had to do an online remote support with me, and completely reprogram my tuner. This also gave the oil temp upgrade that i was wanting. Now i have all accurate temp readings. and i finally found the answer to my fan clutch engauging all the time when i'm towing a heavy load. My oil temp is maxing at 238 just at normal driving speeds, and my coolant jug is still puking "even after the egr cooler delete." i did 2 coolant pressure test to check and see if my head gaskets were bad, but 2 different gauges show a max of 16-18psi, while driving the crap out of my truck. the oil temp is too high , which leaves me to think that i have a clogged up oil cooler, causing the coolant to boil when i comes in contact with the oil cooler. "makes sense to me." and i have just flushed the coolant system and radiator, put in new coolant. Do ya'll think it hte oil cooler too???
Let me know your opinions please. If it's the cooler, which one do you recommed goin back with???
Thanks, jason

We'll need the EOT EOC temps, oil and coolant to verify the Delta. If it is 15+ then yes you need a oil cooler.

Give us that info. and we'll tell you your options.

What are your ECT readings compared to the EOT readings?

[jason]

ect =188
eot= 220
tft= =166
this is after about a 20 min. ride into town with the engine already warmed up earlier today. normal driving hwy speed at about 60mph. i drove yesterday about 25 miles, and the oil temp spiked to 237.
let me know what ya'll think.
thanks, jason

If you just flushed and changed your coolant you can try a reverse flush and see if it clears some of the crap out... But with a delta that high I would say it is probably completely clogged

thats what im thinking myself. that seems like the only logical explanation that my coolant jug is puking still !!! my coolant pressure tests 16-18psi and thats dogging the crap out of it, coolant temp hit like 139 when i did that, and coolant was puking like crazy out of the degas jug.

Keep driving it that way and you will rupture the oil cooler, gel up your coolant, add $$'s to the repair, and maybe ruin some other things.

You could already have a head gasket leak with those pressures in the degas bottle.

count on doing headgaskets, with that much pressure in the system

time for a oil cooler and a egr cooler with those numbers. i would do a flush along with the back flush before i did the coolers. i would add a coolant filter after the flush and run it about +/- 500 miles before i did the new oil/egr cooler.

why do you suggest headgaskets as a default response? Is it not possible that boiling coolant can cause high pressure? unless i'm mistaken steam expands in volume 1700 times!!!!
