My 1984 grand marquis does not get heat
\015 I changed the thermostat,the upper and lower radiator hose is warm. Both heater core hoses are hot. I added coolant and simultaniously squeezed top hose to purge air. I had heat for 5 minutes this morning then none all day. I very rarely ever have heat Once in a great while between. Is thermostat backwards,should I flush Heater core?\015
