Radiator relief valve setting.
The radiator relief valve on my 400 is allowing coolant to dribble out, and at times to run out, when the engine is run up to operating temperature (observed whilst the car is stationary). The radiator has recently had a new core fitted and I have cleaned the ball-bearing (it is brass), cleaned its seat in the top tank and checked the spring. The workshop manual does not offer much advice regarding the spring rating and my spring seems to offer very little pressure on the ball bearing. Any suggestions?
