Dynaflash8 Posted April 4, 2018 Share Posted April 4, 2018 Does anyone know if an OEM five-blade fan on a 1941 Buick makes it run any cooler than the standard 4-blade fan? Link to comment Share on other sites More sharing options...
Mark Shaw Posted April 6, 2018 Share Posted April 6, 2018 It might when it is parked.... The original fan worked when new, so if it isn't cool enough running down the road, the problem isn't the fan. I suggest you check the timing, thermostat, radiator, & flush the engine cooling jacket in that order.... 1 Link to comment Share on other sites More sharing options...
rodneybeauchamp Posted April 6, 2018 Share Posted April 6, 2018 Hi, on page 246 there is a post reference to a “1937 overheating” and some detailed discussion. Not sure but may be relevant to your ‘41. The factory spring in the housing is new to me. Hope this helps Rodney ?????? Link to comment Share on other sites More sharing options...
