    does it overheat?
    it could be a stuck shut tstat or could just be the hose needs to be replaced. replace the tstat first, cheap as crap. or you can test it if you want in boiling water. obviously when the u rev the water pump is moving faster and flowing a higher volume

      If the hose is aged at all and you can actually see it expanding, I would suggest replacing it ASAP. Flowing water should not cause it to be visibly expanding. Even pressure from heat shouldn't be causing that.

        This is the prelude of what I experienced....that ended up in throwing a Rod and needing a new engine.
