Hi,
Recently notices my coolant reservoir fills and does not flow back into radiator after engine cools.
Been using a turkey baster to treansfer fluid from reservoir back to radiator. Fills radiator back up so appears not losing coolant.
Car not overheating (yet) but concerned about summers in Arizona desert.
Appreciate our help and recommendations.
Best,

replace the hose connecting them
Thanks will do.
Try installing a new radiator cap. When the engine cools the coolant contracts and creates a vacuum that pulls the contents of the overflow tank back into the radiator. If your radiator cap is not sealing air is pulled in rather than coolant. (This assumes the tank is just an overflow tank and not a pressurized part of the cooling system.)
Thanks. did replace cap. No change. It is an overflow.
There's not much to that setup, must be a blockage somewhere.
