1958buick Posted April 21, 2005 Share Posted April 21, 2005 Anyone know what the "correct" type of radiator hose was for the 58 Buicks? Formed or flex? Thanks in advance. Link to comment Share on other sites More sharing options...
Pete Phillips Posted April 21, 2005 Share Posted April 21, 2005 A formed hose is ALWAYS correct. To my knowledge, Buick never used a flex hose on anything.Pete Phillips, BCA #7338 Link to comment Share on other sites More sharing options...
NTX5467 Posted April 22, 2005 Share Posted April 22, 2005 I don't think GM or any other OEM North American manufacturer ever spec'd flex hose over moulded hose. Many times, the flex hose is the "replacement" hose when the correct factory-type moulded hoses might have not been available locally, or were discontinued.Think of the flow issues of the coolant flowing over the interior of those flex hoses rather than the factory moulded hoses. Not to mention possible aeration.In some applications, GM did use some straight hose sections with bent tubing in between then. Seems like some middle 1960s light duty truck engines were that way from the factory.Enjoy!NTX5467 Link to comment Share on other sites More sharing options...
