arp studs and puking?

[backwaterz]

I had studs put in about 2 years ago along with egr delete, new oil cooler, heads decked,and all the new gaskets at tbe dealer. they did let me take take the heads and have them machined and tested and all was good. Now 2 years later starting to puke coolant whats going on. I monitored ect-eot delta anywhere from 5-10° different on the highway 75mph for 1 hour. What could it be other than head gaskets agian?? By the way I dont race the truck its a daily driver. I only run ID 65HP tow.

You may just be needing a new Degas Cap...

Well then...


Check the pressure in the coolant resivour... Tee into the line and if it gets over over 16psi


Did you do the work yourself the first time or did a shop do them?

[backwaterz]

I teed into coolant last night it hit 16 psi but I had to run the living s##t out of the truck on a hill

[backwaterz]

I left the tee in this morning and returned the truck to stock and couldnt get it over 12psi

I don't know I give up...




NEXT... What else could it be... umm, have you checked EGR cooler? Oil cooler? Deltas?

oh, duh...

Make sure the coolant is about 3/8-1/2" lower then the "LOW" line in the resivour.

If you overfill it will puke the excess coolant out!
