So my upper coolant pipe is leaking where it goes into the manifold. It is held on by one 10mm bolt that goes through a flange.I can easily get to it to remove but im wondering how easily it will pull out of the manifold? Is there an O-Ring in there that keeps it sealed? If anyone has removed one before any info would be great. Thanks

Is might also be called a crossover pipe that the heater hose pipe is connected to.
