1994 Chevrolet Camaro Z28 Coupe 2-Door 5.7L

I bought this car used in July of 2014. Tags have not been renewed since. We fixed the head gasket last year June 2016 after it blew and have the receipt. The car does run but, unfortunately, one of the hoses either the radiator hose or heater hose is blowing steam which causes overheating after a few miles. The battery is brand new, wheels are new. new spark plugs, thermostat, radiator cap are all new and although, not new we have replaced radiator and cooling fan. I also tinted the windows at 5% back window, 15% passenger side window, 20% driver side window. I put a lot of money on this car and would love to fix it up more but, no longer have much time to spare.
