Recently did some major work to my 95's E300Ds cooling system. Changed the Water-Pump, Thermostat, Water-Pump Housing, etc..) I consequently drained and refilled the system. Coolant temperature is fine, heats up quickly and maintains a steady 85C. Coolant level is also fine. The work was done about two weeks ago, and have driven about 500 Miles since. My question relates to trapped air in the cooling system

In the morning, when the engine is cold, and I squeeze the top radiator hose, I can feel, and hear that it is full of air bubbles. Is this normal? Do I need to bleed the system, or will this entrapped air eventually escape?

Thanks,

Phil
