Chevrolet: heater core, hook ups, vapour lock

Question
i replaced a heater core and have a 195 thermostat installed. the heater does not blow very hot air and i was wondering if i could have a vapour lock in there? If that's the case how do i get it out. The rad is full and everything else is okay. It's got me stumped--it should blow hotter than what it does.Hope you can help me out!!!Thanks--Jim Lane

Answer
HEA JIM;
       FIRST OFF WHAT TYPE OF CAR AND THE YEAR.  I WONDER IF  THE VENT IS NOT OPEN ALL THE WAY. I WOULD LOOK TO SEE IF ANY VENTS ARE CLOSED AND THAT ALL SWITCHES ETC. ARE WORKING PROPERLY , AND COULD IT BE HOOKED UP WRONG ?
AND AS FAR AS THE 195 THERM. THAT IS PLENTY HOT , SO THERE HAS TO BE SOMETHING WRONG AS FAR AS  A VAPOR LOCK I DO NOT THINK SO THAT IS IN FUEL LINES MOST OF THE TIME YOU COULD HAVE SOME   AIR BOUND BUT CHECK THE COOLENT AND BE SHURE ITS FULL AND THAT THE RAD. CAP IS OK. RE-CHECK ALL HOOK-UPS AS IT SHOULD BE WORKING ARE BOTH OF THE HOSES TO THE HEATER HOT GOING IN AND OUT ? IF YES THAN THERE IS SOMETHING CLOSED UNDER THE DASH LIKE A VENT OR SWITCH. OK GET BACK IF YOU NEED MORE HELP.
