overheating at idle

91 318is

The car has 240k and I just replaced the cracked radiator and new thermostat. The fan clutch is fine and the high heat hose is fine. It doesn't leak any coolant and none of my hoses are cracked or worn. It keeps a decent temperature while the rpms are kicked up but at lower rpms or at idle, it immediately begins to overheat. I'm thinking water pump but has anyone heard of those impellars getting worn to the point where they slip like that. Is there some kind of in-line pressure release valve orsomething i should be looking for? Don't wanna replace the waterpump if I don't have to.

Thanks.
Mike

Make sure you bleed it. Also make sure you installed the thermostat the right way with the spring inside the motor.

when you say to "bleed it," do you mean to let the car run for a while with the resevoir cap off to get any air out of the system?

No, open the bleed screw. It should be next to the radiator cap if you have the black plastic tank.
