1978 pontiac firebird trans am 403 6.6 - CAR IS RUNNING HOT , IDLING HOT?

[Ruben V]

Car Has New Thermostat

But When I Open The Radiator Cap And Turn On The Car And Go Check The Radiator With The Cap Off ,i Can See The Car Is Pumping Water Out Of The Lips Inside The Radiator , While Is Filling Up , So I Guess The Water Pump Is Fine ,

But The Gets Car Is Too Hot , The Fan Blows Hot Air , , U Get Glose To The Engine Of The Car With The Hoop Up And U Start Sweating In Like 30 Seconds , The Fenders Get Hot , The Inner Fender ,
The Temperature Gauge Show Betweeen 100 To 220 , And I Can Drive It For Like 1 Hr With Out Any Problem , But It Gets Too Hot , U Cant Touch The Hood Or The Fender , , Because It Will Burn Ur Hands

I Have Another 78 Trans Am With The 400 6.6l Not The 403 And That One Stays Cool , U Can Change A Part Or Have Ur Face In The Carburator Moving It And U Can Feel Cold Air From The Fan ,

Unlike The Other One U Get Close To The Other One And Its Nothing But Hot Air That It Will Make U Sweat In Seconds

Wat Seems To Be The Problem With This 78 T/a 403 ,

If U Have Any Ideas Of How To Fix It , Please Let Me Know

The old school way is to check all your hoses even the heater core ones to see if water is circulation throught the whole system.Even new thermostats can be bad, have bought many of them and returned them.
