| Re: Cooling System - Excess Pressure
Pat, we had several issues with the CAV cooling system, and the advise you have from all of the above is valuable. We also ditched the existing expansion tank and made a new ali tank more as original, at a much higher level to assist air bleeds. We also found it essential to alter or add air bleeds into the radiators that were above the full bore of the coolant pipes, the original CAV position of bleed pipe back to the expansion tank is set too low to ensure that all trapped air is removed from the top of the rad, and thus preventing full flow through the main service pipes. |
