Slightly swollen upper radiator hose?
Hey guys, at the risk of sounding like an idiot I have a question. I noticed the other day that when the car is running, the upper radiator house slightly swells up. If you look at the clamp you will see it start to flare out slightly. It flares out evenly all the way to the radiator end tank on the other side and not one specific area more flared than the other. No other adverse issues with the car (holds temp fine, no leaks, no indications of a failed HG overly pressurizing the system, no milky oil, etc). I should note the car has an FM Crossflow on it so the upper hose is not OEM and before it gets mentioned, the reroute is next. I'm guessing this is normal as the system is under pressure when running? Never noticed this before. Pic attached

as already said, replace.
Rad hoses have a braided sleeve set into the rubber, specifically to prevent them from bulging out (as well as some other stuff)
If it's bulged like that so soon after fitting it i'd suggest that it may have had a manufacturing defect.
Also, with the replacement, try and stick with rubber, rather than silicone.
A good rubber hose should be good for 10+ years (well, here they last that long, not sure on climates where you see snow and stuff)

I should note, when the car is off and cool, it looks perfectly normal. It's when the system is pressurized that it puffs up a bit, so i sort of chalked it up to it being somewhat normal since the coolant system is under pressure. I bought another hose I'm going to try later today
