BigBlockBandit Posted December 28, 2023 Share Posted December 28, 2023 I just wanted to know if it was okay if I ran a 350 sbc radiator without a fan shroud? Its my first older car Quote Link to comment Share on other sites More sharing options...
Dtret Posted December 28, 2023 Share Posted December 28, 2023 It won’t hurt the car to run it without it but you better have an accurate temperature gauge ( not the light) to monitor the coolant temperature. If you overheat the engine you may end up with bigger problems. GM felt that the fan shroud was necessary. Be careful. Do you not have the fan shroud? 4 Quote Link to comment Share on other sites More sharing options...
Michael Boyte Posted December 28, 2023 Share Posted December 28, 2023 Sure ,if you want to add an electric fan. Otherwise not advisable !! Without the shroud, the fan is too far from the radiator to pull much air If you don't move the air through the radiator with force, you're going to have heating issues. 7 Quote Link to comment Share on other sites More sharing options...
FrankOC Posted December 28, 2023 Share Posted December 28, 2023 and dangerous to anyone working under the hood with the engine running. 4 Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted December 28, 2023 Share Posted December 28, 2023 Fan is too far away to run without a shroud as others have said. 4 Quote Link to comment Share on other sites More sharing options...
Marks71 Posted December 28, 2023 Share Posted December 28, 2023 I would stay with the stock sbc fan shroud. About 50% of the fans thickness should be inside the shroud for max efficiency. If this can’t be accomplished then, as Michael said go with electric fans incorporated with their own shroud. 4 Quote Link to comment Share on other sites More sharing options...
