Coolant issue

[Peter56789]

I’ve been having problems with my coolant disappearing. I’ve had head gasket checked, my water pump and timing belt replaced egr cooler replaced. But my car still won’t hold coolant it’s not leaking onto ground anywhere as I’ve been watching it. I drove the car over a week ago and checked how much coolant i had in it before i set off and got home and it was roughly half full i went to check the car today and it had no coolant in the reservoir so i took the cap off and only a quarter of it came back into the reservoir. Thank you in advance for any help

Get a local garage to to a full bleed and refill and go from there.
