antifreeze blowing out the degas bottle

[mdkallam130]

Ok so monday i replaced the injectors in my truck.. all 8 of them... when i cranked the truck up antifreeze started blowing out of the resevoir with the cap on it... it was getting rid of it at a high flow rate.

when i shut the truck off and added fluid its like it was just sucking the fluid down and pulsing a little too....the water would go down then come back up and then go back down again.

also have diesel fuel in the water...

my question is what could this be and where is the fluid going when it goes back down after adding water...

Im thinking maybe a cracked injector cup or a injector not seated properly...or possibly a head gasket...

im not a mechanic just trying to save some money by doing the work by myself and i have never know anyone to have this many problems out of a 7.3 either


any help would be greatly appreciated

the only way to get fuel in your coolant is injector cups IIRC

ok i went out there and checked the truck...with nothing running just added water to

the bottle...i added enough to try and get the water level to remain the


same ....thought possibly air in the system....well after adding about 6 gallons of water i

heard water dripping down on the ground... crawled underneath and looked and it looks

like the water is coming down the side of the pipe that is conncted to what looks to be

like a manifold.... where could this water be coming from /

Sounds like you cracked an injector cup or 2 or 3. When you cranked the truck, the compression from the pistons was pressurizing your cooling system and thus blowing coolant out of the degas. Then when you kept dumping water into it, water went the other way through the injector cups and filled the cyls. with water, the water traveled out the open exhaust valves and is now on your shop floor.

Sounds like you need to pull the injetors again and replace the cups. I hope that is all the damage that has been done.

Good luck.

Your injector cups arent seated properly. Pull em and fix em.

Unless you want severe engine damage
