Customer Question

2012 freightliner cascadia Cummins...
2012 freightliner cascadia Cummins engine. Fault code 111 fit looks coolant comes on just when I turn on the engine after turning it off for a while. Then it turns off stays off as long as I don't turn off engine. I recently changed coolant tank. I wonder if it's a bubble? I also did add water tofull still did the same thing

Hi I'm Wayne

I will help you with this

Thank you for requesting me

not sure what you are telling me,

you have this code, shut down and code goes away ??

Let me know

Customer: replied 11 months ago.
No. The code comes on only when I shut down the engine for little while and then I start the engine. Code goes off when I drive the truck for a while and the fault code never comes on even if keep driving or keep idling for 2-3 days. But once I shut the engine let it cool and turn on the engine. fault code comes on and stays on for about 30 minutes

After the coolant tank was changed topped it with about a gallon of regular water. And it seems to boil off. Do I need to put in coolant only. Does regular water do of while coolant remains?
Customer: replied 11 months ago.
Does regular water burn off quick?
Expert:  Wayne replied 11 months ago.

Morning

Yes regulator water boils off 50% quicker, then a mix

you should always use 50/50 mix

I hope this helped you

I've filled it with 50/50 prediluted. Still something seems wrong because I'm losing a gallon per 200 miles. I've already put in 4 gallons

That sounds like a big job and allot of money that I'd like t to avoid if unnecessary. So is there any visible signs I can look for to know that the head gasket is surely the case?
Expert:  Wayne replied 11 months ago.

Hi

you do not see it leaking any where , Correct

is the exhaust smoke white ish color

let me know

Customer: replied 11 months ago.
After refilling the coolant I run idle for a while looked under and around engine. Didn't see any leak. When I stop I'll check smoke color
Expert:  Wayne replied 11 months ago.

Thank you for that

if you are not leaking it you are burning it

Yes head gasket is pricey, but cheaper then a new engine

head gasket cost is around $4-5 K

I hope this helped you

Customer: replied 11 months ago.
No white smoke at all while idling
Expert:  Wayne replied 11 months ago.

Thank you for that

a gallon in 200 miles is a lot

sitting still set the RPM to 950, and see if it is coming out of the

over flow tank
