Coolant level drop

Hi, I recently had my radiator flushed and now I just noticed that my coolant in my recovery tank is a little low, before I had it flushed I never had the coolant level drop at all, I read somwhere that there could have been some air in the system when they did the work. Anyone have any ideas, thanks

Often when the system is flushed they don't run the engine long enough afterwards for the fluid to get warm enough to open the thermostat, and that leaves air in the block. Then when you drive the car, the coolant gets warm, the thermostat opens and the coolant displaces the air, which comes up to the recovery tank and the fluid level goes down. Just go ahead and add 50/50 water and coolant to the full mark with the engine warm and running. It should then be ok.

Be advised that when the cool fluid hits the thermostat it may close so let it run awhile and have enough time to open again so all the coolant circulates good and double check your fluid level again.
