P0284 and lost coolant after heavy tow

[vinniehobart]

just hauled two 30ft combine headers hooked to each other with my 04 6.0 and when I got to our destination in Colorado and it was loping pretty good (P0284) and noticed it was half a gallon low on coolant(temps were about 230f). When I started it up the next day I filled coolant back up and there was no lope anymore until I started driving and stopped and shut it off and it started loping again. When I pulled these trailers it was 101 out with a 30mph crosswind and going up at steep grade for about 300 miles. My boost pressure stayed above 20psi for most of the journey and I only have a Egr delete and straight pipe. . I also noticed my filter got pretty clogged since we were on chalky roads and harvesting. Didn't know if you had any suggestions.

I would think the lope is high pressure oil related. It didn't puke at all? If the egr is gone and you're losing coolant you may have blown the gaskets.

 

[vinniehobart]

yes it did puke in fact it got all over my intake tube and degas bottle. I filled it back up and drove 400 miles today in 100 degree weather and didn't go down. I wasn't towing anything either. What would I need to do for HPOP? I didn't loose any mileage today either I got 17.5mpg and have no leaks under truck

Well you just overheated it then, that being said I would still keep an eye on coolant level and puking. do you have anyway of monitoring icp?

 

[vinniehobart]

Ya that's just what I hoping for..towing just wasn't in my favor that day but had to be done...no I don't have a way to monitor ICP

 

[vinniehobart]

I have a scangauge 2 but I think I can read ICP but idk how to set it up

By any chance, do you keep the level above the minimum line? If so, that's more than likely your problem. Did you hear the fan kick on at all?

 

[vinniehobart]

No I kept it at min line at all times...yes my fan was coming on all the time

First thing I would do is wash the radiator core, A/C condenser and inter-cooler cores with a garden hose, get all the bugs and debris out so it has plenty of air flow through them. This tool makes the job much easier

If you have never cleaned them before believe me the fins are full of junk to stop the air flow.
