I have à 69 v8 307. When bought it , it have a strang shroud fan whit à fan on thé water pump. I remove all that and installed a 18’’ électric fan . Work fine everywhere except on highway at 60-70 mph after 15-20 min , temp go To 195-200 when outside temps is about 28-30 deg. When its about 20 , it run cooler. Thermostat is new 180 . If after highway , i need To go slowly and hide a something ( need more power ) , temp can go To 205-210 whit the electric fan on .
Il chek 2-3 différent timing and change nothing.
I re installed thé water pump fan , and little bit better , but run at 195 on highway after 20-30 min at 70 mph .
So its possible that only thé fan shroud would Yelp ? It Will force the air To Pass trough the rad ?
Where i can get thé right shroud fan ?
