my 6.0 overheated this weekend and blew about 3 gal out the overflow bottle before I was able to stop and refill. EGR is dry, all tests passed at dealership. They think the edge evolution is bad. I run it in stock mode and was using only for gauges. The previous owner said he used for tow mode. They think it is causing the fan to not kick on properly.

What do you all suggest? I'm happy with ripping the thing out and just using scangauge. What will it take? Any suggestions on what might really be wrong?

I'm going to disconnect from the computer tonight and see what happens.

 

Something caused your degas to puke. I call BS on the bad tuner. Unless they are willing too say headgaskets too.

 

I've heard of the same issue without a tuner. I'd be interested to find out what "all" of the possibilities are.

 

use the SGII to watch the FAN RPMs

at 216 fWT[or ECT] mine fan rpm really picks up to like 800 rpm and up

even ambeint temp plays into the fan speed

hows your ECT vs EOT spread

Id watch all I could with the SGII

 

What year model?

Do you have an EGR delete?

 

X2 here on the tunner being bad causing your issues

could be as simple as a bad thermistate to

post up your numbers with SGII and the other info

 

06 no egr delete. I have been watching ect and eot with my evo and delta typically less than 10. Ect jumped all over though. Climbed to 255 then back down to 220. I believe fan is kicking up at the 215 range. Not real sure what to think. If I try unplugging evo from obd ports should computers go back to normal or do I need to pull whole thing out and does the computer need reset?

 

any coolant puke

start with the easy like a new thermistate

watch the fan rpm with the SGII make shure its coming on

 

He was 3 gallons low I don't think this of asimple fix

 

my bad I didnt read the first post very well thanks Jim

 

hope it aint head gaskets

does it have headstuds?? since it tows tunned

 

No headstuds.

 

do you know if they did a cylinder compression test

 

I don't know. I guess that would test the gasket?

 

Yes gaskets heads piston rings ect...
