I would replace ... and then keep checking the new one ... it warped ... maybe for age or bad material reasons ... but it also could have warped due to high heat ... if it warps a new hose then it means that you need to consider checking your manifold to make sure there is no restriction in water flow which would help offset the heat ....
Just my $0.02 ...... not overly serious but maybe a "clue" to something else going on ....
Keep a tight line, and a smile on your face. Peace out.
