My upper radiator hose was leaky, so I replaced it today. All the coolant in the reservoir drained when I disconnected the hose, so I filled it up again. However, I couldn't find the radiator cap

run the car with the reservoir cap off and topped it off until the coolant level remained stable. Then I put the cap back on, waited some more, then carefully opened it and the level was the same.
After some 10 mins I checked the upper radiator hose and it was hot enough... The temp gauge reads just one bar below the middle...
Question is, will I be fine like this or should I locate the rad cap and top it off through there?
Thanks
