Sounds like the heater and much of the engine is full of air. |

Replace the heater core. Friend had the same exact problem on his 94 grand
Am. He ignored it. Heater core finally started leaking. We replaced the heater core & the overheating went away. |

with engine warmed up if both hoses are hot in and out of heater core
on firewall then heatercore is flowing ok.if one is cold then heatercore is blocked/dirty.you can reverse flush with gardenhose and retry.make sure your radiator fan is coming on when engine gets hot. |

"with engine warmed up if both hoses are hot in and out of heater core

We replaced the > heater core & the overheating went away. Mine is a 95 Pontiac Grand Am and leaks coolant, fogs up windshield, and cannot use heater. Is this my heater core also? |
