Using Coolant

[spinto]

I need some insight here. The shop that did the work is reputable and is baffling them and me. So, here are the symptoms:

-90,000 miles on the truck
-ARP studs -then went back and them re-torque
-Ford headgaskets
-heads were tested and were ok to reinstall


The issue....its using coolant...not puking it out....no white smoke....no leakage.

How much coolant are you using and how long has it been using it.
How long ago was the engine work?
Does the truck still have the egr cooler?


I am assuming it was using coolant and you had a shop replace the head gaskets and stud it, and it is still continues using coolant ??
Have they put a pressure gauge on the cooling system when driving?
Pressure tested the cooling system?

Wonder what was the original torque on the head studs, are they a shop that works on PowerStroke engines namely the 6.0??
Re torquing the cylinder heads after they think there is a coolant leak is a red flag for me.
Questioning the shops experience ^^^

Forgot that little piece of info!! No EGR. Was deleted some time ago.

Engine work was done less than 4000 miles ago.

From when the work was done and we worked through any air trapped in the system, since that time....and as of the past couple of days i've added 3 1/2 gallons.

The studs were done because of the typical issue of blowing out of the degauss bottle and therefore overheating.

Haven't tried pressure test while driving, but i did do a UView test prior to the re-torque and found exhaust gases were leaking into the cooling system. It hasnt been tested like that since. I've order my own kit and will do the UView test.

Regarding the re-torque...it's my understanding is that is the "old" way of doing things and it shouldnt need it if it was done right the first time.

I suspect a cracked head or bad gasket.

Another question...how many times can you retorque the ARPs??
I agree with you on whether they have enough 6.0 experience. They came recommended and do performance work on cummins, duramax and powerstrokes for pulling and regular maintenance.

Hum, exhaust gas in the fluid with an EGR delete... What brand of head-gasket went in before? Were the heads checked for warp and cracks? These 2 items might give you the answer.

ARPs/heads don't need to be re-torqued, but if it were checking to make sure it was done right the first time, at least they were trying to rule out one possibility - gee boss, Billy only did the first or second pass, whoops! However, once it starts leaking, a re-torque usually won't do squat! You can reuse the studs a number of times, as long as they have not been over-torqued.

The truck had never been touched until recently. They use stock Ford gaskets. I was told the heads were properly checked, so i can only assume there were.

Thanks for the info about the torquing of the studs.

My gut tells me that they will have to do the job again!!

3.5 gal in a few days? You would have water flowing out of the tailpipe, or hydrolocked it by now. I i'm interested, and fwiw, I think your shop is less than desirable for 6.0 work. Jmo.

Sent from my phone that somebody didn't help me get.

I have to agree...disappointing and could be a problem getting them to redo their work...and properly...i hope it isn't an issue. Btw....just drove 130 miles...added another gallon when i got home!! The motor has to come apart again...no choice!!

The latest in this saga:
-the shop checked the torque on the studs and they havent backed off.
-the shop kept the truck for the weekend and told me that at a constant speed...75mph for an hr the EOT went to 230 and the ECT ran around 190.
-I have an IPR oil cooler with prob 20,000 miles on it. They did the head gaskets 5,000 miles ago and did a major flushing on 2 sep occasions.
-the shop says it a plugged oil cooler...which it prob is...partially. When i dropped it off to him, the delta didnt exceed 15 degrees.
-but, i'm having them check the water pump first.
-I have little heat at the front and none in the rear. If the system isnt flowing coolant...it cant cool.

I'll know later today.

Updates? Having a similar issue myself.

I didn't hear from the shop today. I expect they replaced the water pump and took it home to test it.
