Why do you say something is wrong with the intake if the hose is the problem? It sounds like a bad hose that is expanding.

Based on original post, the radiator hoses will be pressurized when the engine is running and warms up. That is normal. The radiator cap is set to releaase pressure at 15 lbs of pressure. If the hose is expanding, it sounds bad and you also may want to check the radiator cap to make sure it is releasing when it should. If the hose isn't expanding, please explaine why you feel it is getting too much pressure. I don't want to mislead you.

If the housing is leaking, remove it, clean it, and replace the gasket. Make sure to torque it to the manufacturer's specs. Also, make sure the thermostat is properly seated where the housing is recessed and doesn't move when you replace the housing. Also, make sure that both surfaces are clean, dry, and nothing is warped. I've had housing warp and leak.

Let me know.

Got ya. Is there any way you could upload a picture so I could see how bad it is? A slight bulging could be from the barb on the housing itself. If there are no leaks, you replaced the hose and radiator cap, chances are it is normal. Unless the bulging is excessive. You could try getting a radiator cap with a lower release rating like 12 lbs.
