02 F350 coolant overflowing after injector cups replaced
Hello everyone, I'm a new member first post.
So one day I got home from a trip and noticed coolant spilling on the floor after checking the reservoir I saw some diesel in the coolant, I did some research and found that's due a leaking injector cup or two. So I went to the local parts store and got a new set of injector cups and replaced them all. When I pulled the first injector cup the coolant was still pressurized and some leaked into the cylinder. I pulled the glow pack cranked the motor a few times to clear it out and the rest of the job went smoothly. So now I have a new problem.
When I start the truck the coolant is instantly over pressurizing and blowing out the reservoir and will overheat if it stays on, if I pull off the purge hose (I think that's what is called) from the res. bottle the coolant goes down and so does the temperature but so does a steady stream of exhaust out the hose. I don't know what happened? Could it be a cup didn't seat right? Or the oil cooler happen to fail at the same time? I don't think the head gasket could have magically just blown. I never had any over heating problems before, also there isn't any oil in the coolant nor coolant I the oil. I'm totally confused???? Could anyone help?!?
