So I got this car salvage recently and I have fully built it up. I filled up the coolant last and then took it for a drive. The car seemed to not be getting cooled. I drained the coolant and attempted to troubleshoot a bit. I tried checking if the system was clogged, it wasn't. There wasn't any leaks at all or anything. I am really puzzled! Can anyone help me?

 

Fully built it up? Details about the motor. Did you burp the system after adding coolant?
