overheating

Hoses can 'bulge out' or 'squeeze shut' when they are worn out but I have never heard the term 'spongy' to describe one of those issues. A worn out hose can block or impede flow causing an overheat condition. So, can a blockage in the system, busted thermostat and shorted fan motors. Need to find true cause......take to a different shop for a second opinion. Give them all the info. you can.....
